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

Polini racing clutch with Z23 sprocket for Vespa PX E Lusso 150

The Polini HT clutch is designed for racing use and combines reverse functionality with specifically selectable primary gearing. In this design, the inner hub is connected to the crankshaft; the outer bell does not perform this function. This enables a structurally independent solution for the Vespa clutch drive.

Function and structure

• Pressure plate on thrust bearing for low-friction operation.
• Aluminum bell as part of the clutch construction.
• Cover of the block with oil collecting channel.
• Adjustable spring force to adjust the clutch.
• Straight toothed Z23 pinion for the selected primary gear ratio.

Technical features

The clutch offers the possibility of specifically selecting the teeth of the primary wheel and thus adapting the gear ratios. By replacing the primary gear, the HT clutch can be modified with other available spare parts from the range. The precise and smooth gear shifting supports effortless gear changes.
