Principle of Motorcycle Automatic Clutch?

[LydiaRose]

Motorcycle automatic clutches are mainly centrifugal clutches, with very few other types capable of automatic shifting, which are almost unseen in common models nowadays. Automatic centrifugal clutches are currently primarily used in scooters and underbone motorcycles. Their basic principle involves several flyweights or pressure plates. When the engine speed is low, the flyweights retract due to the spring tension and cannot engage with the outer housing, keeping the clutch in a freewheeling state. As the engine speed increases, the centrifugal force grows stronger, causing the flyweights to overcome the spring tension and tightly engage with the outer housing. This drives the housing to rotate, thereby propelling the wheel and enabling the motorcycle to move.
