The crankshaft allows the engine to be started by means of a lever operated by the rider's foot. Pushing the lever down rotates the shaft, transmitting motion through a series of gears to the crankshaft, generating pressure in the cylinders and facilitating the air-fuel mixture necessary to start the engine. Avoid using the shaft abruptly or forcefully. Push the lever firmly, without excessive force, to prevent damage to the gears. Keep the mechanism well lubricated to prevent wear and corrosion. The crankshaft ignites your motorcycle's engine and your passion for exploring unknown paths and discovering new ones on the road.
