Designed as a premium upgrade for clutch rebuilds, this spring set increases clutch holding power to help reduce clutch slip under demanding riding conditions. The additional lever pressure is designed to remain nearly unnoticeable to the rider while providing a stronger, more consistent clutch engagement.
