Description
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 GPR
The GPR version offered here is a special, closely stepped racing gearbox designed for maximum propulsion on the race track. The first three gears are longer than in series, the fourth gag is significantly shorter. The gear steps between them are shortened from second gear onwards. This results in a sporty, closely stepped gearbox which is only slightly shorter than a standard gearbox (at 9000 rpm in fourth gear approx. 5 km/h). The much more stable gearwheels including auxiliary shaft are therefore ideal for use in racing or for sporty oriented drivers whose engine benefits from a closely stepped gearbox.
(12/58, 13/42, 15/38, 17/37 teeth)
The Benelli GPR gearbox forms a unit and cannot be combined with gearwheels from other manufacturers. It has a special kick starter pinion which is included in the delivery.
BENELLI BULL
The complete gearbox Benelli Bull consists of the GPR set, but additionally contains a reinforced version of the main shaft including shift claw, shift spring, shift balls, shoulder and lock rings. The main shaft is supplied already completely assembled and adjusted.
