Motorcycle BMW reveals R1200GS
The “BMW GS” concept has embodied riding pleasure and the desire for adventure for over 30 years. This applies especially to the GS motorcycles with the opposed-twin “boxer” engine.
The “big GS” allows motorcyclists to explore the most remote corners of the world – an idea that has already inspired numerous globetrotters to set off on their travels.
But the GS was and still is much more than this. Whether sports-style cornering on winding country roads, excellent travel times due to high motorway speeds, relaxed tours with a passenger or daring rides over rough terrain – every GS has offered supreme mastery of these skills in its respective era and this won’t change with the new version.
It is the unique integrated concept of the big travel enduro bike with boxer engine, complete with authentic charm and a powerful, high-torque engine, which is loved by legions of motorcycle fans all over the world to this day. It is not for nothing that the “big BMW GS” with boxer engine has been the undisputed frontrunner in its market segment for many years and is the
best-seller within the BMW Motorrad model range. BMW is now beginning a whole new chapter in GS history: the most popular travel enduro in the world has been brought to perfection.
Geared towards the above goals, the entire R 1200 GS was completely redefined, particularly the drive concept.
The performance aspired to, as well as adherence to future anticipated requirements in terms of noise and exhaust emissions, is ensured among other things by a change in the cooling system. The boxer engine in the new R 1200 GS continues to use air/liquid cooling, however, the coolant oil has been replaced by a glycol-water mixture. This ensures a high level of heat absorption capacity of the cooling liquid for more efficient heat dissipation.
So-called precision cooling (a principle similar to that used in Formula 1) involves only those engine elements being cooled with coolant, which are particularly exposed to thermal stress. The engine still continues to use air cooling, thereby preserving the characteristic appearance of the opposed twin boxer engine. The two radiators are small and inconspicuously integrated.
The through-flow is now vertical instead of horizontal for improved filling, and the engine housing integrates the 6-speed gearbox as well as a wet clutch with anti-hopping function instead of the dry clutch as was used previously. What is more, the secondary drive now runs via the well-established cardan shaft on the left-hand side. With an output of 92 kW (125 bhp) at 7700 rpm and 125 Nm at 6500 rpm, the new engine offers superior power and performance in the travel enduro segment and beyond.
The empty weight (ready for the road) according to DIN of the R 1200 GS is 238 kg including standard BMW Motorrad Integral ABS.
An electromotive throttle actuator is now used for the first time in a GS motorcycle. Here, rider commands are passed on directly by the sensor in the accelerator twist grip to the engine control system; this then regulates the throttle valve electronically. The use of the E-gas system provides a significant improvement in terms of controllability and response. What is more, the rider can adapt engine characteristics to the situation on the road by means of five modes (optional extra). It was also possible to include an electronic cruise control function (optional extra).
The chassis of the R 1200 GS uses a completely newly developed tubular all-steel bridge frame with a bolt-on rear frame. Along with the newly designed Telelever at the front and the EVO Paralever at the rear, this has resulted in a further significant increase in torsional stiffness and hence ride stability and steering precision. Optimised handling qualities are the result of refined master geometric chassis data, and a longer swingarm provides further improved traction – especially when riding over rough terrain.
A globally unique feature of the new R 1200 GS are the tyres in the sizes 120/70 R19 at the front and 170/60 R17 at the rear, specially adapted to improve performance.
The brake system of the R 1200 GS has been extensively revised, too. There are now radially mounted Brembo Monobloc brake calipers at the front and a larger brake disc at the rear.
In line with the BMW Motorrad principle “Safety 360°” the new GS is also fitted as standard with the BMW Motorrad ABS, here in the part integral version.
Even in its standard trim the new R 1200 GS has a main headlight with optimised light efficiency. In order to be seen even better during the day, BMW Motorrad also offers a daytime running light as an ex works option. For excellent road illumination and therefore even greater safety both day and night, an LED main headlight with integrated daytime running light is fitted in a motorcycle for the first time ever. It comprises innovative LED technology with a sophisticated cooling and decondensation concept.
