Details: The new boxer engine externally looks the same, but the first thing you notice is that the shaft is on the left side and the single exhaust system, high, is on the right side, totally in contrast to the R 1200. The cylinders, with a slight fluttering, totally changed: the exhaust manifold out through the bottom and admission is on the upper surface of the cylinder, now in the opposite direction of travel ", with very straight lines. Obviously, the engine is an eight-valve, DOHC, twin spark and fuel injection, although its displacement would be about 1,270 cc, it would give a torque of 14.5 kgm and a power close to 128 hp. What about the radiator? Well camouflaged between the plastic covers and front fenders, which, though different, retain some similarity to the current model. The front of the bike is brand new, more aerodynamic, with a different high fenders and a new asymmetrical headlamps, similar to the F 800.
For now, these are all we could gather data on future R 1300 GS with liquid cooled boxer engine. Given the lateness of its development, the bike seems very well finished, "do not be surprised that the new GS came into production in September this year and give marketing beginning in early 2012. We will be watching.
These are the main new features:
MOTOR liquid cooling of inlet and outlet placed in the top and bottom of the cylinder respectively.
RADIATOR cooling above the rocker Telelever, tucked between the plastic and the front fenders.
CARDAN located on the left side of the bike, totally unlike the current R 1200 engine.
QUIET exhaust exit on the right side. Hold the shaft on the left side there is no room for the passage of the collector. Look at the bags in the other photo.
FRONT modified with new leadership, plastics, fenders, fender high and optical. It closely resembles an actual Adventure R 1200 GS, but different.
