2013 BMW R 1200 GS Preview
BMW Europe has unveiled its highly anticipated 2013 R1200GS, though the information is only specific to European markets and may differ from US specs (BMW reports US-specific info will be available soon).
The R1200GS, which enters its ninth year of production in 2013 and is the top-selling enduro with over 170,000 units sold, receives loads of upgrades, including the newly designed air/water-cooled boxer engine with vertical through-flow, integrated gearbox and left-hand cardan shaft drive.
The new opposed-boxer twin engine produces 125 horsepower @ 7700 rpm compared to 110 horsepower of the last year’s model, and 92 ft. lbs. of torque @ 6600 rpm.
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 The boxer engine in the new R 1200 GS continues to use air/liquid cooling, however, the coolant oil has been replaced by a glycol-water mixture.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.
Besides the enhanced power, the European-specific R1200GS also had some weight shaved, and arrives in 2013 with a dry weight of 525 lbs.
Following are the highlights of the 2013 BMW R 1200 GS, which are further explained beneath the bullet points:

Following are details of the new features of the BMW R1200GS:
E-gas and cruise control
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).
ASC and riding modes as an optional extra: five freely selectable modes – “Rain”, “Road”, “Dynamic”, “Enduro” and “Enduro Pro”
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
Semiactive suspension: BMW Motorrad Dynamic ESA for optimum riding dynamics in every situation as an ex works option
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.
New chassis with tubular steel bridge frame and specially adapted wheel/tire dimensions of 120/70 R19 at front and 170/60 R17 at rear as a world first
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 tires in the sizes 120/70 R19 at the front and 170/60 R17 at the rear, specially adapted to improve performance.
Revised brake system with radially mounted Brembo Monobloc brake calipers and BMW Motorrad Integral ABS as standard
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.
The first motorcycle in the world with LED main headlight including integrated daytime running light for even greater safety when riding during the day and at night as an ex works option
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.
Electrical system with new vehicle power supply and Multi-Controller for the BMW Motorrad Navigator IV
The new R 1200 GS has the innovative new vehicle power system with altered function partitioning as already used in the 6-cylinder models K 1600 GT and GTL. As before, CAN bus (Controller Area Network) and LIN bus technology (Local Interconnect Network) enables significantly reduced wiring as compared to a conventional system. The previous central vehicle electronics has been partitioned into two separate control units.
The Multi-Controller, newly available for the GS, allows fast and convenient operation of the BMW Motorrad Navigator IV. It is located on the inside of the handlebar grip. This means that selecting functions is much less distracting than pressing buttons and does not require hands to be removed from the handlebars.
Aerodynamically optimised windshield with one-hand operation and optimum ergonomics
The newly developed windshield of the R 1200 GS offers further improved wind and weather protection while also reducing wind noise. Adjustment is simple: an easily accessible and ergonomically optimised selection wheel is operated using one hand.
The new R 1200 GS has extended adjustment options for optimum seating comfort. The rider’s seat can now be adjusted in height and tilt angle and the passenger seat can be shifted longitudinally to obtain the ideal distance between rider and passenger. The new handlebars can easily be turned upwards and, together with the optimised knee grip in the fuel tank area, they ensure an even better standing position for off-road riding. The improved knee grip can be clearly felt when seated, too. A high and a low seat, as well as an adjustable footrest system and adjustable foot controls, round off the program of special accessories offering individual adjustment facilities.Google+
