On almost all road bikes, the crankshaft turns in the same direction as the wheels. But as with Motogp bikes, the new Panigale V4 gets a counter-rotating crankshaft. Its benefits are in gyroscopic effect and inertia, improving handling and directional agility.
A counter-rotating crankshaft produces inertia-linked torque in the opposite direction, lowering the front of the bike, limiting the bike’s desire to wheelie, and therefore boosting acceleration performance.
Similarly, during hard braking/deceleration the bike undergoes rear wheel liftup: however, the crankshaft itself also decelerates, producing an inertial torque that works against rear wheel lift-up, too.
