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

POLINI racing clutch Z22 with straight teeth for Vespa PX 150

The POLINI HT clutch combines reverse functionality with specifically designed components for the Vespa PX 150. Unlike a conventional design, the part connected to the crankshaft is the inner hub and not the outer bell. The Z22 pinion with straight teeth enables a suitable selection of the primary gear ratio within the POLINI-HT clutch system.

Function and design features

• Pressure plate on axial bearing for defined clutch actuation
• Aluminum bell as part of the clutch construction
• Block cover with oil collecting groove
• Aluminum discs reinforced with 8 teeth for power transmission
• Adjustable clutch spring force

The spring force can be adjusted to the desired coordination. In addition, the teeth of the primary gear can be selected to fine-tune the translation. This version has a primary gear with Z=22 and straight teeth. Replacing the primary gear allows for later adjustment of the POLINI HT clutch using designated spare parts.
