Cruciform gear selector Polini for Vespa Small frame and PX.
The gear selector and gear selector cruciform represent, for all the Vespa models, are a key component for the proper functioning of the gearbox but they are particularly stressed.
It is precisely for these special needs that the Polini engineers have designed a series of gear selectors for the most popular Vespa Small Frame and PX models, produced with high quality steel which allows to
achieve very high hardness / resiliency features.
The engagement teeth must be superficially very hard to withstand the sliding wear but, at the same time, they must have a very high resiliency to resist the shocks which a transmission is constantly subject to.
The complex geometry of the Small Frame models requires a careful machining to have a low roughness on the gear engagement cam.
The mechanical features, well above the original ones, make the gear selectors essential for the tuned engines. In case of assembly on standard engines, they grant higher reliability and longer life.
