Benelli Drag Cluster auxiliary shaft with 34 teeth for Vespa PX and T5

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 the necessary elasticity to withstand the enormous loads in a racing engine.

The Drag Cluster version offered here is a special, very close-ratio racing gearbox designed for maximum propulsion on the racetrack. For normal road use, it should primarily be combined with the longest possible reduction ratio (BGM 25/62) in order to achieve a sufficiently high top speed.

In direct comparison with a PX200 standard gearbox, the BENELLI Drag Cluster, in its shortest version (12-13-15-15), has all four gears in the range of what the standard gearbox already covers with three gears. This means that the fourth gear with the Benelli is as short as the third gear of the standard gearbox (assuming a primary reduction ratio of the same length).

Benelli uses a special gearwheel with 34 teeth for 4th gear for its Drag Cluster gearboxes, which is supplied with the auxiliary shaft. The Drag Cluster transmission is only compatible with this gearwheel. Gears 1-3 can be combined with the standard gearwheels of the PX/Cosa 125-200 models. The Drag Cluster auxiliary shafts are used with a special ball bearing (15x32x13mm), which is also included.

A longer 1 gear with 55 teeth is also available. This is compatible with all 12-tooth first-gear PX sprockets. This sprocket can be used in a PX old gearbox with cranked sprocket as well as in the modern Lusso gearbox with flat sprocket.

Benelli offers three differently stepped auxiliary shafts (the values differing from the original gearbox are printed in bold):
