Description
Commitment and racing experience have led Polini designers to develop two new primary transmissions with straight teeth with flexible coupling and reinforced clutch bell.
The one-piece, heat-treated, case-hardened clutch bell allows the driving discs to work by dragging on all six sides, thus reducing their wear.
The flexible coupling counter-flange, also in case-hardened steel, guarantees maximum strength, allowing the clutch bell to be removed. The springs in special high-strength steel are calibrated to prevent the transmission from breaking.
Specific for both Vespa 50 and 125, the new transmissions are interchangeable with the original parts and it is recommended to fit them on modified engines or engines with more than 25hp.
