Vespa PX T 5 [1985-1993] - racing clutch with Z22 sprocket with helical teeth

POLINI racing clutch with Z22 pinion for Vespa PX T 5

The POLINI HT racing clutch is designed for the Vespa PX T 5 built between 1985 and 1993. The Z22 pinion with helical teeth enables a suitable selection of the primary gear ratio and thus supports the tuning of the drive.

Function and structure

With this design, the inner hub takes over the connection to the crankshaft, while the outer bell no longer performs this function. The reverse functionality forms the basis for POLINI's HT clutch concept. A pressure plate on axial bearings supports the controlled actuation of the clutch.

• Aluminum bell for the HT racing clutch
• Reinforced aluminum discs with 8 teeth
• Adjustable clutch spring force
• Z22 pinion with helical teeth
• Primary gear can be replaced to adjust the gear ratio

Technical features

The reinforced aluminum discs are designed for efficient power transmission. The adjustable spring force allows the clutch to be adapted to the desired setting. The interchangeable gearing opens up additional options for matching the translation with suitable POLINI or original primary gears. The design supports precise and smooth gear changes.
