BMW K1600GT / K1600GTL preview

BMW reveals details about new six-cylinder tourers
By Motorcycle.Com Staff, Jul. 05, 2010
BMW Motorrad has revealed information about its upcoming six cylinder K-series motorcycles.

Back in November, BMW introduced its inline-six Concept 6 model at the 2009 EICMA show in Milan, Italy, with the news the engine will power future models in the companys K-series tourers. The future is now closer to becoming the present with the announcement of the upcoming BMW K1600GT and K1600GTL.

BMW's sketches give us an idea of what the K1600 models will look like. Note the 55 degree forward tilt of the engine cylinders which, BMW says, lowers center of gravity and improves air intake.

The BMW K1600GT is the sportier of the two with an upright seating position. The K1600GTL is designed for longer rides with the footrests placed lower and further forward while the handlebars reach further backward for a more relaxed sitting position. Both models will come with removable panniers while the K1600GTL adds a topcase. As for aesthetics, BMW has only released design sketches of the two models offering a glimpse of what the final product will look like. BMW has released a fairly detailed look at the headlight cluster which has an owl-like appearance with two halogen high beam lights with lighting rings surrounding a central xenon headlight (more on the headlight technology below).

The shape of the K1600's headlights looks almost owl-like, especially with the light rings inherited from BMW's automobile division.

Both models will run on a 1649cc six-cylinder inline engine developed from BMWs automobile technology. BMW Motorrad engineers adapted the inline-six engine to make it light enough and compact enough for use in a motorcycle. The result , according to BMW, is a powerplant that weighs 226 lb. and measures 560mm in width, about 100mm narrower than previous inline six engines used in motorcycles. BMW claims a peak output of 160 hp at 7500rpm and torque of 129 ft-lb at 5000rpm with 92.2 ft-lb. available at 1500rpm.

The engine is equipped with BMWs E-Gas ride-by-wire throttle control system. The E-Gas system has three modes, Rain, Road and Dynamic, all available at the press of a button on the right handlebar.

According to BMW, the engine delivers over 70% of its maximum torque at just 1500rpm.

While the engine is the focal point for the new models, the rest of the bike has not been ignored. The chassis is based on the current K-series frame with Duolever front and Paralever rear suspension. An ESA II (Electronic Suspension Adjustment) system offers quick switching between three suspension settings, Sport, Normal and Comfort. The K1600 models will come standard with BMWs EVO brake system with integral ABS. The new bikes will also use BMWs Dynamic Traction Control system introduced in the S1000RR.

BMW also developed a new headlight system that will compensate for the K1600 models pitch and banking angle. The main headlight uses a centrally positioned movable xenon projection module with reflector mirror. The system compensates for the motorcycles pitch using data from level sensors in the front and rear axles. The optional Adaptive Headlight feature, a first for motorcycles, uses a stepper motor to turn the reflector mirror in relation to the banking angle. The result, as illustrated in the following video, is improved illumination while cornering.

Another first for a motorcycle is a 5.7-inch multi-function color TFT LCD monitor offering the kind of display usually found in high-end automobiles. The monitor displays text and graphics and automatically illuminates in low light conditions. The K1600 models will also use the multi-controller first introduced in the R1200RT. Located on the inside of the left handlebar grip, the multi-controller offers control over menus on the TFT monitor, allowing operation of the on-board computer, ESA II system, navigation as well as grip and seat heating.

The TFT display shows information such as the Electronic Suspension Adjustment settings.

The multi-controller also operates the audio system, found standard on the K1600GTL and available as an option on the K1600GT. The system uses MP3 player, iPod and USB memory stick input, as well as satellite Sirius XM radio.

BMW will release further details about the K1600GT and K1600GTL at a later date. Check back here at for an upcoming feature on BMWs new six-cylinder models. For now, take a look at more images from BMW on our gallery.
