BMW K1300GT


The BMW K1300GT

Introducing the new K 1300 GT, BMW Motorrad is opening up new dimensions in the BMW Touring Encounter World in terms of both riding dynamics and grand touring qualities, enhancing the Company’s worldwide leadership in the Dynamic Tourer segment.

Offering even greater supremacy all along the drivetrain, an even higher standard of quality, an aerodynamic fairing enhanced to a new level of perfection, and a wide range of special equipment, the new K 1300 GT stands for Gran Turismo of the highest caliber.

It combines maximum agility and sporting riding dynamics with the ideal package for long tours. And with its engine output 118 kW (160 hp), together with maximum torque of 135 Newton-meters (99 lb-ft), the new K 1300 GT also benefits from the increase in engine size and stands out as one of the most powerful motorcycles in its segment.

In typical BMW style, therefore, the new K 1300 GT meets the greatest demands in terms of riding dynamics, comfort, safety, and equipment.

The new K 1300 GT is a High Performance Tourer featuring the innovative and proven highlights of the new K 1300 S in terms of performance, riding safety and technology. The drivetrain and suspension come largely from the K 1300 S, but have been adapted in their specific features and details to all the requirements of a dynamic tourer.

The highlights in developing the new K 1300 GT were enhanced riding dynamics and even greater supremacy combined with outstanding comfort and optimum qualities for all kinds of motorcycle tours.

Identical in its basic features with the power unit of the K 1300 S, the engine has been modified in terms of air flow and guidance. This increases maximum output over the K 1200 GT by 6 kW (8 hp) to a new record level of 118 kW (160 hp), with even greater emphasis given to superior torque for even better traction and pulling force at low and medium engine speeds.

The K 1300 GT also sets the standard in terms of comfort, riding safety and equipment, not only through its excellent suspension and running gear, but also through optionally available, electronically adjustable ESA II (Electronic Suspension Adjustment II) as well as features such as electronic cruise control, an electrically adjustable windshield, or seat heating controlled individually for the rider and passenger.

BMW K1300GT Technical Highlights – an Overview:

  • Even more traction and pulling force, particularly at low and medium engine speeds, through the increase in engine capacity.

  • Engine output 118 kW (160 hp) at 9,000 rpm, peak torque of 135 Newton-meters (99 lb-ft) at 8,000 rpm.

  • Significant increase in torque from 3,500 rpm.

  • Fulfillment of the strictest environmental standards through newly set-up Digital Motor Electronics.

  • Optimization of the emission system through rear mufflers modified inside and a fully-controlled three-way catalytic converter.

  • Desmodromic operation of the gas lever function for even better and more precise gas metering.

  • Optimized, maintenance-free shaft drive with a new, two-stage drive shaft.

  • Even greater driving precision and optimized response combined with maximum riding stability ensured by the optimized Duolever front-wheel suspension complete with a newly designed lower longitudinal arm.

  • Second-generation ESA II Electronically Adjustable Suspension and ASC Anti-Spin-Control as an option.

  • New, innovative generation of switches and controls with optimized ergonomics.

  • Integral ABS (semi-integral) featured as standard for a high level of active safety.

  • Wide range of equipment and accessories tailored to the new machine at BMW’s usual high level of perfection.

  • Seat and handlebar are adjustable.

  • Optimized full fairing.

  • Electrically adjustable windshield.


BMW K1300GT Engine
Like the K 1300 S, the new K 1300 GT also benefits from the significantly upgraded straight-four power unit increased in capacity from 1,157 to 1,293 cc.

Maximum output is now 118 kW (160 hp) at 9,000 rpm, with peak torque of 135 Newton-meters (99 lb-ft) at 8,000 rpm. This equals an increase in power by 6 kW (8 hp) and an increase in torque by 5 Newton-meters or 3.7 lb-ft.

While the former K 1200 GT did not develop its maximum output until 9,500 rpm, the power unit of the new K1300 GT offers its maximum power at 9,000 rpm, with more than 80 per cent of the engine’s maximum torque available from just 3,500 rpm.

Again versus the K 1200 GT, the torque curve is significantly better over a wide range from 3,500 – 10,000 rpm, following the objective to offer significantly more traction and pulling force particularly at low and medium engine speeds.

The torque curve remaining at a high ceiling over a wide range of engine speed is indeed virtually ideal for the K 1300 GT as a genuine Gran Turismo, offering even more practical performance and supreme power than its predecessor, which already set the standard in this segment.

While all features optimized on the engine and drivetrain of the new K-Series also benefit the new K 1300 GT, the airbox has been specifically adjusted to the different air requirements and flow conditions within the engine, featuring an optimized air filter and newly set-up intake funnels versus the former model.

Exhaust System
The rear muffler, which is newly designed and configured, also contributes to the even “beefier” torque curve and enhanced riding qualities of the K 1300 GT, standing out clearly through its supreme and powerful rumble.

Contrary to the very sports-minded K 1300 S and K 1300 R, the exhaust system on the K 1300 GT with its substantial damper volume and consistent use of stainless steel throughout does not require an electronically controlled exhaust butterfly.

Gearshift
The BMW K1300GT does not have the new BMW Gearshift Assistant feature. It uses an optimized anti-friction bearing on the gearshift lever with a corresponding reduction in tolerance in the transmission of power ensures an even more precise and faster gearshift than ever before.

Suspension
While the new K 1300 GT is based on the particularly stable suspension geometry of its predecessor, the unsprung masses of the BMW Duolever have been reduced even further through the introduction of a newly designed lower longitudinal arm. Now made of forged aluminum, the new Duolever gives the motorcycle an even smoother and finer response.

BMW’s new ESA II (Electronic Suspension Adjustment II) suspension is also available on the K 1300 GT as an option at extra cost. This allows the rider, apart from the damping on the two spring struts, to also adjust the spring base (spring pre-tension) on the rear spring strut as well as its spring rate and spring hardness smoothly and conveniently at the touch of a button.

Hence, the owner is able to set the suspension most conveniently and more precisely than ever before to their personal wishes, taking particularly the load the motorcycle is carrying into account (which is of particular significance with the K 1300 GT) and offering a new dimension of riding stability combined with optimum response under all riding and load conditions.

ESA II is the world’s first electronic suspension control on the motorcycle offering such a wide range of adjustment options.



Brakes
The new K 1300 GT is equipped with BMW’s proven EVO brake system also featured on the other models in the K- and R-Series.

Brake discs measuring 320 millimeters (12.6") in diameter up front and 294 millimeters (11.6") in the rear guarantee optimum deceleration also from high speeds and under maximum load.

Featured as standard, BMW Motorrad Integral ABS (semi-integral) not only fulfils the highest demands in terms of safety, but also caters for the wishes and preferences of the sports-minded rider through its special set-up and configuration: BMW Motorrad Integral ABS controls the front- and rear-wheels brakes through the handbrake lever, while the footbrake lever acts only on the rear-wheel brake.

Controls
The new K 1300 GT boasts a brand-new generation of switches and manual controls. Using MID (Moulded Interconnect Devices) technology, the new switch and control units are far smaller and more compact, while at the same time offering a higher standard of functionality, clear design and optimum accessibility.

The switches for the electrical adjustable windshield, the handle and seat heating as well as cruise control are all integrated in the control units on the K 1300 GT.

Like the K 1300 S, the new K 1300 GT comes with a newly designed speedometer and rev counter with an even more dynamic layout on its scale. These two units are supplemented in the digital instrument cluster by the Info-Flatscreen, an information display consistently providing all the information the rider requires on data such as coolant temperature, tank capacity, the time of day, or the gear currently in mesh.

When fitted with ESA II (Electronic Suspension Adjustment II) as an option, the flatscreen provides additional information on the current suspension setting. Other data available on request are the current mileage of the motorcycle, trip mileage and – once the fuel level has dropped to reserve – the remaining range. Any deficiencies or defects, finally, are shown in the display by appropriate signs and symbols.


Options and Accessories
The new K 1300 GT stands out as a genuine Gran Turismo through its ideal combination of sporting performance and touring comfort provided right from the start even in standard trim.

And to raise this standard to an even higher level, BMW Motorrad offers a wide range of optional extras and special equipment, optimizing this Dynamic Tourer in every respect.

These features will thrill both the demanding Grand Touring rider looking for maximum comfort on long distances and the technology enthusiast in search of innovative technical features.

The wide range of functional options extends from an on-board computer through a xenon headlight all the way to the ESA II (Electronic Suspension Adjustment II) suspension allowing the rider though simple and optimum adjustment of the spring and dampers to set the running gear to the rider’s current requirements.

Optional extras come straight from the factory and are fitted during production. Special equipment is fitted by the BMW Motorcycle Dealer also subsequently after the motorcycle has been delivered.

Colors
The new K 1300 GT offers perfect harmony of touring qualities and sporting riding dynamics – features also reflected by the design of the K 1300 GT with its flowing lines and clear, striking shapes and surfaces.

The lines tapering out towards the front symbolize even more power and dynamics than before, combined with sporting and slender all-round proportions.

The three main colors available for the body are Red Apple Metallic, Royal Blue Metallic, and Magnesium Beige Metallic, contrasting perfectly with the drivetrain finished in Black and the suspension components in Asphalt Metallic.

While Red Apple Metallic in conjunction with dark contrasting components on the spoiler and at the rear appeals particularly to the sporting and ambitious rider, the experienced touring rider will definitely enjoy Royal Blue Metallic with White Aluminum contrasting components as a puristic alternative.

A third variant offers an even higher level of elegance and modern style: Magnesium Beige Metallic contrasting with Dark Slate Metallic, matt.

Styling
The unusually slender full-fairing with its dynamic contours and excellent aerodynamic qualities has been carried over from the former model and upgraded in its looks for the new K 1300 GT.

The new fairing differs from the former unit at the side through an opening in the side panel and the logo support, giving the K 1300 GT a far more dynamic appearance. The inner surfaces of the fairing now fully painted and no longer in the conventional grain touch convey an even higher standard of quality and style.

And at the same time the inner surfaces are further upgraded by the instrument panel now finished in a matt, dark metallic color. Protectors integrated in the side sections reduce the risk of damage in a fall or accident. Hence, the machine is now well protected should it fall over in an accident or when not properly parked.



Rider Comfort
The new K 1300 GT comes with the electrically adjustable windshield already featured and proven on the former model, combining optimum protection from wind and weather with minimum dimensions.

Through its aerodynamic design and configuration, the windshield guides the wind rushing by round the rider, relieving his head and upper body of wind pressure also at high speeds.

A further important point is that the windshield may be adjusted electrically over a range of 100 millimeters or almost 4 inches from the left handlebar controls, thus consistently meeting the rider’s requirements. A higher windshield (+ 60 mm, almost 2.4") is available as an optional extra, offering virtually every rider perfect protection, regardless of his size and riding position, simply by choosing the right windshield and adjusting it accordingly.

To ensure maximum comfort and freedom of movement, the seat, as on the former K 1200 GT, is designed around the so-called step arch length of the rider as the decisive criterion for seating quality. This particular measurement is the distance between the rider’s two feet on the ground – measured across the inside of the legs – also taking the shape and the width of the seat into account.

The seat is tapered significantly around the rider, enabling him to comfortably place both feet on the ground and bend their knees just as comfortably. A further point is that seat height may be adjusted as required to 820 or 840 millimeters (equal to 32.3 or 33.1").

And for the somewhat shorter rider BMW Motorrad offers a lower seat as an optional extra measuring 800 millimeters or 31.5" in height (adjustable to 820 mm or 32.3”).

Both with a sporting style of riding and when touring, the “ergonomic triangle” made up of the footrests, the seat and the handlebar guarantees maximum freedom of movement as well as a relaxed style of riding without the slightest fatigue.

And last but certainly not least, the passenger will also enjoy the high standard of seat comfort so typical of a BMW. Handlebar adjustable for height. As on the K 1200 GT, the handlebar is adjustable for height in four levels, covering a total range of adjustment towards the rider’s body of 40 millimeters or almost 1.6", thus adapting to all kinds of riders of different size and allowing the rider to choose their ideal seating position at all times. The height of the handlebar is adjusted very conveniently and easily through a mechanical thread-and-bolt setting.

BMW HP2 Sport


Technology such as the self-supporting and aerodynamically optimized fairings made completely of CFK, the gear shift assistant, a dashboard similar to that used in the MotoGP, the forged aluminum wheels and brakes with radially mounted calipers make the HP2 unmistakably athletic on both country roads and race tracks.

The most striking difference between the BMW HP2 Sport from the endurance racing Boxer is the brand new cylinder heads: each of the double overhead camshafts (DOHC) uses a drag lever to actuate the valves that are larger than those on the BMW R 1200 S.

Further modifications, such as the flow-optimized intake and outlet, new forged pistons and adapted connecting rod, help the engine to achieve the necessary higher output compared to the basic engine. A new stainless steel exhaust system is placed below the engine for the first time, keeping the lower area of the motorcycle extremely slim for greater freedom of movement for a "hanging off" riding position.

Although designed for racing prowess, the BMW HP2 Sport does not forego the safety benefits of ABS. A sophisticated antilock brake system, specially adapted to the HP2 Sport, is available as an option and is configured so that it can be deactivated for the racetrack.

Following the BMW Motorrad Motorsport design, the carbon-fiber bodywork of the HP2 Sport is partially painted in Alpine White, while the engine spoiler carries the two-tone "HP2" lettering and the lattice frame and wheels are painted in the BMW Motorrad color of Motorsport Blue.

1. Concept, Requirements and Features
The dream of many Boxer fans has come true: With the new BMW HP2 Sport, BMW Motorrad is putting the sportiest, most powerful and lightest Boxer series of all times on the road.

The third model of the HP model range was designed for the ambitious sports rider and enthrals with numerous exclusive details that were previously restricted to racing, some making their first appearance in series vehicle production.

Examples of these include the self-supporting and aerodynamically optimized fairings made completely of CFK, the gear shift assistant, a dashboard like that used in the MotoGP, the forged aluminum wheels and the racing brakes with radially bolted calipers. Wherever the eye of the spectator wanders, it sees pure racing technology that delights every enthusiast. It is unmistakably athletic, a vehicle that inspires on country roads as well as on the racing circuit.

Regardless of the limits for the engine output as a result of the principle and the aerodynamic disadvantages from the cylinder configuration of a Boxer, BMW Motorrad deliberately decided to further develop this historic engine concept for a road racer with racing circuit talent.



Sports info centre: GP dashboard from 2D systems

A real highlight for all racing enthusiasts is the production-line dashboard in the cockpit of the BMW HP2 Sport. It was developed in collaboration with the acclaimed company 2D Systems that also deploys its systems in GP racing for data recording and analysis.

The system has a large, easily readable digital display and works in different modes. It is operated by two switches on the left handlebar control.

In road mode the rider can view typical information such as revs, speed, time, kilometers, remaining distance and driving time on the display and is shown supporting information during the warm-up phase of the engine.

In race mode the screen provides data about circuit times, maximum revs, top speed or number of gearshifts, for example. The stored data can also be read out with a laptop. In addition there are eight freely programmable LEDs
in the upper area of the dashboard that can be used as a rev display or external gearshift light.

Like the other functions, the displays are also freely programmable. Finally, the GP dashboard offers a large number of expansion options. A lap timer with transmission/receiving unit, GPS tracking or datalogger can
be connected to a free input.



Adjustable footrest system
The range of high-grade racing components includes the adjustable footrest system made of milled, high-strength aluminum. An eccentric cam is used to adjust the height of the footrests and to move them forwards or backwards.

Stepped setting positions of the footrests make sure that identical adjustment is possible on both sides. At the same time, the likewise fully adjustable brake and gear lever allow optimal positioning of the operating elements.

Adjustable stock handlebar and Magura manual fittings
Also the stock handlebar of milled forged aluminum is ideally positioned and can be adjusted by changing the offset. The Magura radial manual controls allow manual lever width setting of the brakes and clutch.

All Carbon fiber composite fairing
All the fairings of the BMW HP2 Sport are made from carbon where the single-part rear as well as the front fairing are realized as self-supporting elements. The latter has a noticeably slimmer construction than the BMW R 1200 S and houses lightweight, high-luminosity halogen twin headlamps with free-formed surface reflectors. Special details include the number plate carrier of the BMW HP2 Sport: It can be removed along with the tail lamp and indicators
in a few easy steps before taking part in a race.

Refinements in the wind tunnel
Like every BMW Motorrad the new BMW HP2 Sport was also given its finishing touches in the wind tunnel. Not only were components such as the windshield and new rear-view mirror optimized from an aerodynamic aspect; the engineers also paid particular attention to the airflow for cooling the engine.

So the front spoiler guides the air stream specifically towards the outlet side of the cylinder heads while the BMW ‘kidneys’ in the front fairing guarantee an effective flow of the double-oil cooler. Lastly, elaborate ventilation openings in the carbon tail ensure that the heat of the underseat exhaust system is efficiently deflected.

BMW HP2 Sport - Dashboard

Sports info centre: GP dashboard from 2D systems
A real highlight for all racing enthusiasts is the production-line dashboard in the cockpit of the BMW HP2 Sport. It was developed in collaboration with the acclaimed company 2D Systems that also deploys its systems in GP racing for data recording and analysis.

The system has a large, easily readable digital display and works in different modes. It is operated by two switches on the left handlebar control.

In road mode the rider can view typical information such as revs, speed, time, kilometers, remaining distance and driving time on the display and is shown supporting information during the warm-up phase of the engine.

In race mode the screen provides data about circuit times, maximum revs, top speed or number of gearshifts, for example. The stored data can also be read out with a laptop. In addition there are eight freely programmable LEDs

Like the other functions, the displays are also freely programmable. Finally, the GP dashboard offers a large number of expansion options. A lap timer with transmission/receiving unit, GPS tracking or datalogger can
be connected to a free input.




DOHC cylinder heads, valve actuated by drag lever
A complete redesign of the cylinder heads allowed the Boxer to reach higher revs. Extensive tests in endurance events followed in addition to the usual tests. Double overhead chain driven camshafts (DOHC) and valves actuated by very light drag lever now enable top revs of 9500 min–1.

The four radially arranged valves ensure extremely compact combustion chambers so that there is no need for the second spark plugs as used in the R models until now.

The compression ratio is 12.5:1. Super Plus with 98 RON is recommended as the fuel for optimum performance although the motorcycle can also run on Super 98 RON.

The horizontal arrangement of the camshafts introduces two special features: Each of the shafts controls an intake and outlet valve and the cams are conically ground. For a higher gas throughput, the valve plate diameter was increased from 36 to 39 millimeters (intake) and from 31 to 33 millimeters (outlet) respectively.

The intake channels were machined for optimization. The operating technology with drag lever works with shims sitting on the valves as in the K 1200 engines. The cylinder head covers are made from carbon and fitted with easy-to-replace slip pads made from PA6 hard plastic.

High-strength and lightweight forged piston
The bore and stroke ratio is unchanged in the HP2 Boxer. The high-strength, weight-reduced forged piston and the correspondingly adapted conrod are new.

Interacting with the new intake pipe system with its a short intake air funnel, the power plant develops a top performance of 96 kW/128 bhp at 8750 min–1 and a maximum torque of over 115 Nm at 6000 min–1.

Flow through two parallel and consecutively switched oil coolers
So that the Sport Boxer operates well under all conditions from the thermal aspect, two oil coolers positioned one after the other and with a parallel flow-through are deployed.

Wind tunnel optimization of the BMW ‘kidneys’ in the front fairing ensures an effective flow through the double oil cooler.

Stainless steel exhaust system with active exhaust gas flap
For the first time the 2-in-1 exhaust system made completely from stainless steel is placed under the oil sump. This configuration guarantees optimum angles of tilt when riding. An exhaust flap in front of the double exhaust pipe silencer at the rear and actuated by an electronically controlled servomotor via cable produces a fuller torque curve.

A fully-controlled catalytic converter cuts exhaust gas emissions. Oxygen sensors in the two header tubes monitor the oxygen level and guarantee an optimum air-fuel ratio over the entire torque band.

An example of the great attention to detail that characterizes both the development and production of the BMW HP2 Sport is the exhaust pipe fixtures on the single-piece, self-supporting carbon rear. These are thermally decoupled while, at the same time, compensating for the change in length of the exhaust system during warming and cooling.

The hump also boasts sophisticated ventilation openings, used to effectively deflect the heat away from the underseat exhaust. Additional features of the exhaust system are the highly attractive design and the impressive Boxer sound that escapes from the high-volume silencer.



The key engine data are very respectable: the engine achieves more than 96 kW/128 hp at 8750 min–1 compared with the significantly modified engine of the BMW R 1200 S. The maximum torque lies at 115 Nm at 6000 min–1, the highest revs of the engine reaches a peak value at 9500 min–1.

Technically, the BMW HP2 Sport is based on the BMW R 1200 S. Customized to meet the requirements of the ambitious sports rider down to the last detail, the BMW HP2 Sport is however a completely independent and absolutely exceptional motorcycle. Many detailed solutions are based on the experiences gained in long-distance races.


The most striking difference of the BMW HP2 Sport from the endurance racing Boxer is the brand new cylinder heads: Each of the double overhead camshafts (DOHC) uses a drag lever to actuate the valves that are larger than in the BMW R 1200 S. Further modifications such as the flow-optimized intake and outlet, new forged pistons and adapted connecting rod help the engine to achieve the necessary higher output compared to the basic engine.

The new stainless steel exhaust system is placed below the engine for the first time. This keeps the construction of the lower area of the motorcycle extremely slim, enabling great freedom of movement for the familiar ‘hanging off’ riding position, and the fitting of a CFK engine spoiler is advantageous to the aero-dynamics. An inimitable boxer sound with new acoustic quality is generated by the exhaust system and the striking design of the rear silencer is impressive.

Another exclusive racing feature is the gearshift assistant together with the narrow ratios of the 6-speed gearbox to enable fast gear changes without having to ease off the gas and operate the clutch. This technology is offered for the first time in a series vehicle.

In order to adapt the gearshift pattern for the racing circuit, a suitable replacement pressure sensor is available as special equipment if necessary. The fully adjustable Öhlins sports chassis also has a Brembo monoblock brake system with radially mounted, four-piston fixed calipers at the front.

Optimum ergonomics are ensured by the adjustable forged aluminum footrests, the adjustable stock handlebar and the Magura brake levers with radial mounted brake actuators. The series dashboard that comes directly from MotoGP sport provides the rider with important information and can also deliver lap times plus other racing relevant data as well as the usual displays (see Chap. 3).



Exclusive forged wheels and racing tires
The BMW HP2 Sport runs on specially developed, weight and stability optimized, surface-milled forged wheels of size 3.5 x 17” or 6.0 x 17”.

These are considerably lighter than conventional die-cast wheels, but have comparable high stability. The handling characteristics benefit enormously from the smaller rotating masses. The sports Boxer is really easy to steer on bends and allows incredibly rapid change of direction.

The forged wheels are fitted as standard with sports tires in 120/70 ZR17 format at the front and 190/55 ZR17 at the rear. These tires from renowned manufacturers – generally used only on the racing circuit such as the Supersport championship, for example – are homologated for use on asphalt road surfaces. The engineers decided on a 55 series tire cross-section as this achieved the best results for the overall characteristics in tests.

Brembo monoblock racing brakes
The braking system of the new BMW HP2 Sport also presents itself as uncompromisingly sporty. Single-piece, radially mounted four-piston brake calipers from Brembo that hold the two 320-millimetre discs powerfully
in its grip are used on the front.

The radial screw connection is effected by a new die-cast foot on the lower part of the Telelever. A double sliding piston decelerates the rear wheel. It goes without saying that the hydraulic application of the brake calipers is activated by high-quality, steel armored brake lines.

Modified, switchable BMW Motorrad ABS is optional
BMW Motorrad offers an ABS adapted to sporting events as an option. The function of the system has been optimized to prevent the rear wheel from lifting.

An additional pressure sensor in the front brake circuit provides sensitive regulation of the system and the control unit prevents the front wheel brakes from opening too early when the load on the rear wheel is greatly reduced. Nevertheless the ABS can be deactivated for racing events.

Racing ergonomics
Even at the outset of the development, the engineers focused on the seat position. Compared to the BMW R 1200 S, the rider moved closer to the handlebar resulting in a notably more upright seat position oriented towards the front wheel and behind the ‘waistline’ of the fairing.

More importantly, the remarkably slim design of the tank area favors the rider’s weight displacement (hanging off) on the racing circuit. The BMW HP2 Sport also benefits here from the experiences gained in long-distance races where it is not only a question of speed, but also of staying power. Because the rider finds a suitable, but comparatively relaxed, riding position for racing, the new BMW Sport Boxer offers genuine endurance qualities.


The engine spoiler carries the two-tone “HP2” lettering. The lattice frame and wheels are lacquered in the BMW Motorrad color of Motorsport Blue.
