Transmission parts from Stefano Benelli 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 necessary elasticity to withstand the enormous loads in a racing engine over the long term. The gears correspond in the gradation to those of the series transmission and can therefore be combined with all corresponding auxiliary shafts designed for series transmissions. (US)
