Benelli Gearbox (gears + gear cluster) Product Code: BE21616KT
Type GPX. The GPX version offered here is a special, very closely stepped racing gearbox designed for maximum propulsion on the race track. For normal road use it should be combined primarily with the longest possible reduction (BGM 25/62) to achieve a sufficiently high top speed.

In direct comparison with a PX200 series gearbox, the BENELLI GPX, in its shortest version (12-12-15-15), has all four gears in the range of what the series gearbox already covers with three gears. This means that with the Benelli the fourth gear is as short as the third gear of the standard gearbox (assuming the primary reduction ratio is of the same length).

The GPX auxiliary shafts are used with a special ball bearing (15x32x13mm), which is also included.
