Vespa PX 150 [1978-1997] - racing clutch with Z22 sprocket with helical teeth

POLINI racing clutch Z22 with helical sprocket for Vespa PX 150

The POLINI HT clutch For Race combines reverse functionality with a gear selection tailored to the Vespa PX 150. With this design principle, the area connected to the crankshaft is not designed as an outer bell, but as an inner hub. The helical toothed pinion with Z22 supports the adjustment of the primary gear ratio.

Function and construction

• Pressure plate on thrust bearing for precise and smooth operation
• Aluminum bell
• Block cover with oil collecting groove
• Aluminum discs reinforced with 8 teeth
• Adjustable clutch spring force

The coupling makes it possible to adapt the spring force to the desired area of application. In addition, the teeth of the primary gear can be selected to coordinate the translation. By replacing the primary gear, the POLINI HT clutch can be modified with other available spare parts from the range.
