NOTE: This head fits all years of the CRF250R and CRF250X. It's a very popular head for both CRF250R and CRF250X models. It does not have the emissions port so keep this in mind. With Kibblewhite valves and valve springs this is a performance head with excellent durability. CRF250X owners expect to see up to 4 HP improvement with increased throttle response.
