POLINI racing clutch Z22 with helical teeth for Vespa PX E Arcobaleno 200

The POLINI HT racing clutch For Race is intended for the Vespa PX E Arcobaleno 200 from the 1981-1997 model year range. This version has a primary gear with Z=22 and helical teeth. This means that the coupling can be used specifically with the appropriate gearing.

Structure and functionality

With the innovative reverse operation, the part connected to the crankshaft is the inner hub and not the outer bell. The design combines several features designed for power transmission and operation:

• Pressure plate on thrust bearing
• Aluminum bell
• Cover on the block with oil collecting groove
• Aluminum discs reinforced with 8 teeth

Setting options

The spring force of the clutch can be adjusted. It is also possible to select the teeth of the primary gear to adjust the translation. The Polini HT Clutch For Race can be modified by replacing the primary gear with other available spare parts. The gearshift is designed for precise and smooth gear changes.
