Are you looking to go beyond the absolute pinacle in performance to give you a supreme advantage out on the track?  Do you want to win races, rather than spending time mid-field?  Then the NEW PRO-COMPETITION BULLY is the clutch that will take you there!

The 1" Bore Bully range of clutches are designed for ultra-high horsepower 270+cc engines with outputs in excess of 20hp.

35 Pitch 4-Disc-Type Pro-Competition Clutch suit High Performance 4-stroke engines.

Suits Standard 19mm Drive Shaft (1") as used on most 9-13hp engines.

Includes ROLLER BEARING 14T Sprocket.

Fully adjustable engagement from ~2700rpm through to 5600rpm.  No springs required - easy to adjust.  This clutch will not only outlast other clutches when coupled with a high-rpm 4-stroke engine revving upwards of 8500rpm but it will also provide easy and convenient adjustment of engagement speed so that you can match the torque curve of your engine - allowing faster exits from turns.

Complete unit with Drum and Clutch.  Assembled ready-to-go.

All Individual components available from CPR so if you break something, you can just buy the bit that breaks rather than replacing the entire clutch!

Need dimensions?

Outer diameter of the housing is 100mm
In stationary state the depth including levers is 71mm (measured from the outer extent of the inner shaft on the drive sprocket side of the clutch to the farthest point on the levers)
The levers will protrude approximately an additional 7mm at high rpm.  It is recommended to leave at least 10mm free space between the levers and your seat, 15mm+ is better and shroud your seat with alloy plate as a safety precaution.
