Description

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 Drag Cluster version offered here is a special, very closely stepped racing gearbox designed for maximum propulsion on the race track. For normal road operation it should be combined primarily with the longest possible gear reduction (BGM 25/62) to achieve a sufficiently high final speed.

In a 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 the primary reduction ratio is of the same length).

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

Additionally available is a longer 1 gear with 55 teeth. This is compatible with all 12 tooth first gear auxiliary shafts for the PX. This sprocket can be used in a PX old gearbox with cranked spider as well as in the modern Lusso gearbox with flat spider type.

Benelli offers three differently graded auxiliary shafts (in bold print the values deviating from the original gearbox):

	1st gear	2nd gear	3rd gear	4th gear
Original PX125-200	12/57	13/42	17/38	21/35
BENELLI GPX short	12/57 (opt. 55)	13/42	17/38	17/34
BENELLI GPX short (+2.gear short)	12/57 (opt. 55)	12/42	17/38	17/34
BENELLI GPX extra short	12/57 (opt. 55)	13/42	16/38	16/34
BENELLI GPX ultra short	12/57 (opt. 55)	13/42	15/38	15/34
