Clutch bell Polini Vespa Primavera / PK 125 2T 69 straight teeth

Complete clutch bell 27/69 straight tooth Vespa Primavera/PK Polini.

The commitment and experience in competitions have led the designers at Polini to develop two new primary transmissions with straight teeth featuring a flexible coupling and a reinforced clutch bell.

The one-piece, case-hardened clutch bell allows the drive plates to operate on all six sides, thus reducing their wear.

The counter-flange of the flexible coupling, also made of case-hardened steel, guarantees maximum strength and allows for the disassembly of the clutch bell. The special high-strength steel springs are calibrated to prevent transmission breakage.

Specifically designed for both 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.

To adapt the ratios to different uses, there are two different toothed wheels available with teeth calculated to mesh with those of the
Polini clutch bell:
code 202.1419 - Front sprocket Vespa 125 Z=28 longer ratio
code 202.1420 - Front sprocket Vespa 125 Z=26 shorter ratio
