Stage6 9 piece clutch spring will work with the original scooter clutch or the Stage6 Sport Pro clutch. By using harder clutch springs the clutch will engage at higher speeds when the optimum RPMs are achieved resulting in a much better "pull" from a standing start. ***Will not work with Stage6 Torque Control Clutch**
Applications:
Yamaha Zuma 50cc
Only works with original clutch and Stage6 Sport Pro clutch
