Benelli layshaft set for Vespa Smallframe with short 4th gear

Stefano Benelli transmission parts rightly 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, Benelli parts offer exactly the perfect balance of sufficient hardness and the necessary elasticity to withstand the enormous loads in a racing engine.

The auxiliary shaft offered here for Vespa smallframe engines (e.g. PV125, ET3, PK) has a sportier gear ratio than the original. The fourth and even the third gear have a shorter reduction ratio, which means that the gear jumps are smaller and the engine remains in the full power range after shifting. Therefore ideal for powerful engines whose speed must be kept at a constantly high level in order to always develop full propulsion.

The Benelli auxiliary shafts can be used with the original gears of the Smallframe models (PV125, ET3, PK). Only the fourth gear is replaced by the enclosed Benelli gearwheel with 49 teeth.
Benelli offers three differently stepped auxiliary shafts (the values differing from the original gearbox are printed in bold)
