Description

Heavy duty gearbox made in italy by Stefano Benelli

Gearbox parts from Stefano Benelli rightly enjoy a very good reputation among Vespa riders. If you are looking for reliable technology for your gearbox, you will find it here. Hardened to an average 60 HRC, Benelli parts offer just the perfect balance of sufficient hardness and necessary elasticity to withstand the enormous loads in a racing engine or strong touring engine with lots of torque.

FUTURE ORIENTED
From Benelli there is a very nice variant for fast and strong street engines with the Grantour variants. Modern engine concepts not infrequently achieve more than twice the torque of a PX200 from the factory. The Grantour gearboxes therefore use the same high-strength base material as well as tempering as Benelli's hypersport GPX gearbox parts.

100% DURABILITY
Together with a clever design of the gears, Stefano Benelli ensures extreme durability of his gearboxes. In doing so, he reduces the number of almost all meshing teeth and thus achieves two things:

The tooth base becomes wider and thus significantly more stable
By reducing the number of teeth on the auxiliary shaft AND main shaft, the reduction ratio is kept almost the same

DISTRIBUTIONS
The Grantour gearboxes are available in two versions

Touring (12/55, 13/40, 16/35, 19/33)
Sport (12/55, 13/40, 16/37, 19/35)

TOURING
The Touring version is almost identical in its gradation to that of a PX125, making it identical to that of a PX200 with a short fourth gear. A combination equally proven and popular by its range and gradation. Together with a longer primary gear ratio (e.g. 24/62) it is perfectly suitable to combine it with a high performance and high torque engine concept with so called box exhaust. In contrast to the usual short fourth gear with 36 teeth (original from the PX125/T5 models), Benelli's third and fourth gear has a whopping three teeth less and is thus designed to be ultra stable. Perfect for Quattrini 244 & Co.

SPORT
The Sport version has significantly shorter gears in third and fourth than the Touring version. It is therefore ideal for powerful engines with resonance exhaust. With the shorter gradation, the primary reduction ratio can be made long for a good top speed and the engine still has full gear connection at all times.

AVAILABLE
The Grantour gearboxes are available as

small set: 4 gears + auxiliary shaft
large set: 4 gears + auxiliary shaft + main shaft + shift cross

CONCLUSION: If you want your engine to have uncompromising durability with high torque and power, you should put the Benelli gearbox on your shopping list.
