Small primary gear -BENELLI 2.56->2.76- Vespa V50, PV125, ET3, PK50, PK80, PK125 - 25 tooth (straight)

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.

Benelli offers a reinforced primary kit for the Smallframe engines. Here, reinforced shock absorber springs are used to cope with the high torque of a revised engine. Unlike original springs, these no longer go on block. This means that the springs are not completely compressed but still have sufficient travel. This means that load peaks are no longer introduced into the transmission and the components are protected despite higher engine performance. The primary kit is delivered ready to install and has reinforced cover plates for the primary springs.

The additionally available primary pinions are an optimal supplement to adapt the engine to another race track or modified components. This allows the reduction ratio of the existing primary kit to be lengthened or shortened in a wide range.
