Vespa PX E 125 [1981-1997] - racing clutch with Z22 sprocket straight teeth

POLINI racing clutch Z22 with straight teeth for Vespa PX E 125

The POLINI HT clutch for race is intended for the Vespa PX E 125 in the 1981-1997 model year range. This version has a ring gear with Z22 and a straight-toothed pinion. This allows the primary gear ratio to be specifically adjusted using the selected gearing.

Structure and function

With the reverse operation of the POLINI HT clutch, the unit connected to the crankshaft is designed as an inner hub. The outer bell therefore does not take on this function. The design includes a pressure plate on thrust bearings, an aluminum bell and a cover from the block with an oil collection groove.
