Polini HT racing clutch with Z24 sprocket for Vespa PX E Arcobaleno

The Polini HT Racing Clutch For Race combines reverse functionality with the ability to specifically adjust the gear ratio.

The Z24 pinion with straight teeth is designed for a suitable primary gear ratio.

• Pressure plate on thrust bearing for smooth operation
• Aluminum bell as part of the clutch construction
