Vespa PX E Arcobaleno Electric Starter 150 [1981-1997] - racing clutch with Z23 sprocket straight teeth

POLINI racing clutch with Z23 sprocket for Vespa PX E Arcobaleno 150

The POLINI HT clutch is designed for racing use and uses a reverse mode of operation: in this design, the unit connected to the crankshaft is the inner hub rather than the outer bell. This creates an independent technical solution for the Vespa clutch structure.

Function and technical features

• Pressure plate on thrust bearing for clutch actuation
• Aluminum bell
• Cover of the block with oil collecting channel
• Pinion with 23 teeth and straight teeth
• Adjustable clutch spring force

The clutch enables the selection of the appropriate toothing of the primary wheel in order to adapt the gear ratios to the respective application. The primary gear can be replaced if necessary. This means that the clutch can be modified with other available gears from the POLINI spare parts range. The design is designed for efficient power transmission and precise, smooth gear changes.

Vehicle assignment

Suitable for the Vespa PX E Arcobaleno Electric Starter 150, built between 1981 and 1997.

Factual note

The straight gearing with 23 teeth must be taken into account when selecting the appropriate primary drive. Different gearings and numbers of teeth are available for coordination.
