VRF1200F- The new engine incorporates the single overhead camshaft distribution system called "Unicam" which was tested on Honda's offroad machines. This compact system reduces engine size, allowing it to be placed further forward in the frame while lowering the bike's center of gravity. This allows for better front wheel traction when cornering. A 28° positioning of crank pins and a specific [clarification needed] firing order of the cylinders resulted in an engine with perfect primary balance. Because of this, there is no balance shaft, further lightening the engine.[14] Instead of conventional direct mechanical connection from the rider's twistgrip to the throttle, electronic throttle control ("throttle by wire") commands the engine control unit to modulate engine power output. The configuration of the cylinders is also unusual. The V4 has the rear bank of cylinders paired closely together, with the big ends of their connecting rods on the inner sides of the crank journals. The forward bank of cylinders is conversely set outboard of the rear bank, with the big end journals mounted on the outer sides of the crank journals. This design allows for a much narrower engine at the rear, which makes the bike slimmer where it contacts the rider, and allows an easier reach to the ground from the seat.
