Made of Anticorodal, it is therefore more impact resistant than the original. It has an enlarged cavity for mounting Rekluse clutches and increases the volume of oil available on the clutch assembly. This results in smoother operation under extreme conditions, where the clutch is most stressed. For some motorcycle models, the special internal design significantly improves clutch behavior.
