Clutch Central Hub Yamaha TMAX 500/530 Kymco AK 550

Clutch Central Spring Yamaha TMAX 500 / 530 Kymco AK 550. The central spring is responsible for improving the belt's grip on the pulley, exerting a contrasting force so that the pulley opens due to centrifugal force at a different RPM.

These springs made of silicon alloy with high carbon content will maintain good elasticity and reduce deformation, being a durable and quality replacement that will enhance the engine's performance and achieve a quicker and more aggressive response across the entire RPM range.
