Polini reinforced clutch spring set for Minarelli AM6 50cc 2-stroke engines with 70cc+ cylinder kits.

This kit can be used to upgrade standard clutches, perfect for increased torque, to prevent clutch slip. The reinforced springs increase the load on the clutch plates, increasing the amount of power that can be transmitted through it.

For 70cc engines the shim is not used.
For 100cc engines the shim is used to increase the spring pre-load.
