2013 BMW R1200GS – First The look’s the same, but almost else is new.

BMW has revolutionized its boxer-Twin. It is not the first time, but from traditional air cooling cooling, lately) to liquid symbolizes the most radical from the reasons that, in led BMW technician Max Friz to turn 90 an already-existing longitudinal boxer-Twin to the R32 model. This was the first featuring a transversely mounted that cooled much than when placed to the original orientation.

Now, BMW calls “precision cooling,” from its experience with One engines, circulates a specific only around the sections of the that experience the highest the heads and upper section of the where hot combustion gases The rest of cooling remains to air circulating through appropriately fins.

The coolant is based on glycolethylene that used in aircraft engines and allows the use of two inconspicuous to keep the BMW R series’ “clean” Compared to the previous air/oil system, this latest one weight by six pounds.

The new retains the same 101.0 x bore-and-… measurements of the previous but that is where the commonality The thermodynamic section is totally new and more rationally designed and out than it was in the last “radial-valve” that, among other included camshafts with one and one exhaust cam lobe each. the dohc valvetrain is simplified and by a single loop of chain.

Valve diameters are 40mm and 34mm (exhaust), and the valves are at 8 degrees and 10 degrees, respectively, for an angle of only 18 degrees. narrow included angle and the cam followers are also inspired by F1 The combustion chamber is very and a 12.5:1 compression ratio has achieved with slightly pistons for a high thermodynamic

The engine breathes through 52mm throttle bodies to a claimed 125 horsepower at 7700 rpm and foot-pounds of peak torque at rpm. The crankshaft is now much compact, thanks to the reduced of the connecting rods and consequent parallel misalignment of the opposing This was possible thanks to the diameter of the crank journals, 48mm to 50, which increased the capacity of the related bearings, reducing their width.

The main journal diameters reduced from 60mm to 55. The new is more rigid and lighter. The misalignment of the cylinders causes rocking imbalance and related and favors the much-higher rotational needed to produce the new level of


Also new are the oil-bath multi-disc and six-speed gearbox, which is now integrated into the crankcase for compactness and smoothness of operation. The new is a slipper-type, and the shaft drive lighter components. The final and single-sided swingarm are now moved to the side.

The new R1200GS abounds electronic controls. Throttle is “by wire,” and the five riding and modes (Rain, Road, Enduro and EnduroPro) are rider-selectable. Of ABS and traction control are included.

the engine, the frame is only revised. The new GS spans the same inches and has its steering geometry set at a 25.5 degrees for 3.9 in. of trail. Telelever suspension now sports with diameters reduced 41mm to 37, while swingarm has been increased from in. to 23.1. BMW electronically managed ESA suspension is included.

Specifically developed for the GS, front and tires are Metzeler Tourances, front and 170/60-17 rear. new Metzelers are more touring-oriented, and the new GS Brembo Monobloc radial-mount calipers in combination with 305mm rotors to haul the big to a stop.

With a new LED headlight and a protective and easily adjustable the new—revolutionary, even—engineering in the R1200GS is not all but the boxer retains its signature look. Maybe more for GS fans and BMW, it retains the key of BMW-ness created nearly a ago by Max Fritz. Nobody mistook the R32 for else on the road, and nobody mistake the latest R1200GS for else, either.
