POLINI PRIMARY GEAR, STRAIGHT TEETH FOR VESPA

POLINI PRIMARY GEAR, STRAIGHT TEETH FOR VESPA SMALL FRAME AND 125ET3


The engagement and the experience with the races have driven Polini to develop the new primary gears with straight teeth with flexible coupling system and reinforced clutch basket.

The clutch basket is machined from a block and with case-hardening thermal treatment lets the conductor discs to work on all the 6 sides reducing their wear.
The counter flange of the coupling systems made of case-hardened steel too, grants the highest resistance allowing to remove the clutch basket too.
The springs made of high-resistance steel are calibrated to avoid the break of the gear itself.
The new gears, specific both for Vespa 50 and 125cc, are interchangeable with the original parts. It is recommended to install them on elaborated engines or over 25hp.
To adapt the gears to the different situation 3 different sprockets are available with specific teeth to match the teeth of the Polini clutch bell:
Item 202.1418 – Primary sprocket Vespa 50 Z=25 72 -long gear
Item 202.1419 – Primary sprocket Vespa 50 Z=28 72 -long gear
