Clutch bell Polini Vespa Primavera / PK 125 2T 72 straight teeth

The commitment and experience in competitions have led Polini's designers to develop two new primary straight-toothed transmissions with flexible coupling and reinforced clutch bell.

The one-piece clutch bell, subjected to case-hardening heat treatment, allows the driving plates to operate on all six sides, thus reducing their wear.

The counterflange of the flexible coupling, also made of case-hardened steel, guarantees maximum strength, allowing the removal of the clutch bell. The high-strength special steel springs are calibrated to prevent transmission breakage.

Specific both for the Vespa 50 and the 125, the new transmissions are interchangeable with the original parts. It is recommended to install them on modified engines or those with more than 25hp.
