Has BMW perfected the travel enduro bike with their all-new 2013 R 1200 GS?
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.
Engine: Newly Designed
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 The boxer engine in the new R 1200 GS continues to use air/liquid cooling, however, the coolant oil has been replaced by a glycol-water mixture.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.
Five freely selectable riding modes
For optimum adaptation to the rider’s individual needs and purpose, the new R 1200 GS now offers five freely selectable riding modes for the first time: these are an ex works option and feature three different E-gas settings and with varying engine characteristics. Linked to this is Automatic Stability Control ASC with a special enduro configuration. If this option is chosen, BMW Motorrad ABS, ASC and – if installed – the semiactive suspension are all adapted to the respectiveprofiles of these five modes
The new semiactive suspension BMW Motorrad Dynamic ESA (Electronic Suspension Adjustment) taps into a whole new range of possibilities as well as providing maximum riding safety and performance. Dynamic ESA monitors the vertical movement of front and rear wheel control as well as other parameters by means of a spring travel sensor in each position, and adapts the damping automatically to the situation depending on riding conditions and the manoeuvres being carried out. Damping adjustment at front and rear is effected by means of electrically controlled regulation valves.
