BMW 650 GS and 650 GS Dakar

 

 

 

The F 650 is powered by a BMW-designed, single-cylinder engine embodying technologies not seen on other "thumpers." For 2005, the engine's technological resume stretches to include 2 Spark ignition for the four-valve cylinder head and a new and advanced BMS-C II computerized engine-control unit that dynamically manages spark and fuel delivery to suit any riding condition.

With these improvements, the liquid-cooled, 652cc engine produces fewer harmful exhaust emissions, is more fuel efficient, and has a torque peak at 4800 rpm instead of the previous model's 5000 rpm. In addition, the 2 Spark ignition system offers increased drivability, stronger mid-throttle response and greater engine flexibility. As before, the GS uses a three-way catalyst in the updated, stainless-steel exhaust system to meet the stringent Euro2 exhaust emissions requirements.
