Vespa PX 200 [1981-1997] - racing clutch with Z22 sprocket with helical teeth

POLINI HT racing clutch Z22 with helical teeth for Vespa PX 200

The POLINI HT clutch for race is intended for the Vespa PX 200 in the 1981-1997 model year range. This version has a Z22 pinion with helical teeth and thus enables the selection of a suitable primary toothing to adapt the translation.

Function and structure

The clutch works in the opposite way: the part connected to the crankshaft is the inner hub and not the outer bell. The structure is therefore based on a specially designed clutch concept for the Vespa PX.

• Pressure plate on thrust bearing
• Aluminum bell
• Lid with oil collection groove
• Aluminum discs reinforced with 8 teeth
• Z22 pinion with helical teeth

Tuning and driving behavior

The spring force of the clutch can be adjusted. In addition, the teeth of the primary gear can be selected to adjust the translation. The primary gear is replaceable in this clutch system, allowing the clutch to be modified with available replacement parts.

The reinforced aluminum discs support power transmission. The structure is also designed for precise and smooth shifting, so that gear changes are possible with little effort.

Vehicle assignment
