CRF's Only Sprocket Conversion Kit
This kit allows you to use any standard CRF250R/X and CRF450R/X rear sprocket. Kit includes six (6) bushings to reduce the OEM 10mm sprocket bolt holes on the stock CRF250L hub to 8mm to match the CRF250R/X and CRF450R/X hubs. As a result you can now have access to a wider range of sprockets choices, colors and sizes. Also includes sprocket bolts, nuts and washers.
