Vespa PX T 5 [1985-1993] - racing clutch with Z23 sprocket with helical teeth

POLINI racing clutch with Z23 pinion for Vespa PX T5

The POLINI racing clutch is intended for the Vespa PX T5 built between 1985 and 1993. Their reverse operation moves the unit connected to the crankshaft from the outer bell to the inner hub. This creates a specially designed clutch solution for racing use.

Structure and function

• The pressure plate works on a thrust bearing.
• The clutch has an aluminum bell.
• The cover of the engine block has an oil collecting channel.
• The aluminum discs are enlarged by 8 teeth and support efficient power transmission.
• The spring force of the clutch can be adjusted.

Translation and gear changing

The helical Z23 pinion allows the selection of suitable primary drive gearing to adjust the gear ratios. The clutch can be modified by replacing the primary gear with other available spare parts from the POLINI catalog. This means the translation remains flexible for later adjustments.

The design is designed for precise and smooth gear changes. This supports controlled operation of the gearshift and makes it easier to change gears while driving.
