Vespa PX 150 [1978-1997] - racing clutch with Z24 sprocket straight teeth

POLINI racing clutch Z24 for the Vespa PX 150

The POLINI HT racing clutch with Z24 pinion and straight tooth design is intended for the Vespa PX 150 in the 1978-1997 model year range. Their reverse operation connects the crankshaft to the inner hub instead of the outer bell. This makes it a technically independent clutch solution for use in the appropriate Vespa engine.

Function and structure

• Aluminum bell for clutch construction
• Pressure plate on thrust bearing
• Reinforced aluminum discs with 8 teeth
• Lid with oil collection groove on the block
• Z24 primary gear with straight teeth

The reinforced discs support effective power transmission. The spring force of the clutch can be adjusted so that the clutch characteristics can be adapted to the respective application. The primary gear is replaceable within the POLINI-HT system. This allows the gearing to be selected for an adapted translation.

The construction is designed for precise and smooth switching operations. This product is assigned to the Vespa PX 150 from 1978 to 1997. The version with Z24 and straight teeth is suitable for the appropriate selection within the POLINI coupling system.

Factual note

Various spare parts and primary gears are available in the POLINI catalog for adapting the clutch. The gearing should be selected to match the desired gear ratio of the vehicle.
