As with the MotoGP prototypes, the crankshaft rotates in the opposite direction to the wheels. This configuration opposes the gyroscopic effect, to the benefit of handling and agility when changing direction, as well as reducing the tendency to wheelie in acceleration.
The valves are closed mechanically, ensuring the same precision as the opening phase. This allows for the use of more extreme cam profiles and timing that optimizes the dynamic flow of intake and exhaust fluids, for an increase in performance. The camshafts are controlled by two “silent” timing chains. Front end, the chain drives the intake camshaft, which in turn transmits the movement to the exhaust camshaft via a pair of gearwheels, for a mixed gear and chain system. At the rear, the chain drives the exhaust camshaft, which transmits the movement to the intake shaft.
