The bgm PRO Superstrong Smallframe clutch is the ultimate Plug & play solution - Made in Germany. You will get a ready to fit clutch that works perfectly up to a range of 22 hp at the rear wheel and 20 Nm torque.
The hub, top and pressure plate are made from 42CrMo4. Die power transmission is done by the bgm Racing red clutch plates
Smooth contact pressure by 16 bgm PRO XL springs
The springs are used are the well known and established bgm Pro XL springs
Thanks to the quantity and the positioning of the springs on the highest possible radius, the clutch lever action is very good and it is easy to pull. Tilting or being putted cross wise of the two clutch pressure plates is avoided this way. Thanks to the perfect setting of spring stifness and quantity together with the solid made top plate, the clutch can even be easily operated with the PK XL1 clutch cover.
Contact pressure of the bgm Pro XL springs and the friction coefficient of the reacing red plates are perfectly suited for powerful applications. One of the first samples was tested at our X-Mas duell engine
Solid and well engineered clutch hub
The clutch hub is made for a primary drive with cushion drive. For re-assembling it has an inner thread of M28x1, so that mearly every Vespa electzronic ignition flywheel puller will do the job. Thanks to the inner thread the material around the cone is much thicker. The super strong design is completed by the lack of the woodruf key slot. One thing that never made sense on the hub and was a weak point on powerful engines forever. For fitting we recommend our clutch nut
