1st gear cog -BENELLI- Vespa PX125, PX150, PX200, T5 125cc, Cosa - 55 (-2) teeth

Stefano Benelli's gear parts enjoy a very good reputation in the racing scene.
If you are looking for reliable racing technology for your gearbox, you will find it here.
Hardened to an average of 60 HRC, the Benelli parts offer exactly the perfect balance of sufficient hardness and necessary elasticity to withstand the enormous loads in a racing engine permanently.

In addition to all Vespa PX125-200 transmissions, Benelli offers a longer 1 gear with 55 teeth. This allows the 1 gear to be extended significantly longer and the jump to second gear is significantly shorter. Ideal in combination with a modified transmission ratio of the auxiliary shaft. This way a tightly stepped racing gearbox can be created that is ideal for tight courses or acceleration races. It fits on all 12-tooth first gear shafts, e.g. all 125-200ccm original Piaggio or Benelli shafts.
