Renthal Rear Sprocket Twinring KX+F 80- RMZ250 04-06 47t G

A long lasting durable off-road sprocket developed over 5 years. The unique flat face design keeps weight to a minimum and means the Twinring rear chainwheel is as narrow as a standard chainwheel. Outer is expanded at 200°C and then fitted to inner, creating a permanent bond for the life of the sprocket.
