Unleash your build with a CJR Performance CRF110F Race Head for your stock bore or big bore 110! One of the biggest restrictions we find with the 19+ CRF110F is the intake and exhaust port along with the OEM valve springs. With the new race heads you can bring up to +20% to +30% more power (varies for different build specs) through the entire rpm range and an increased RPM limit with top end power that keeps pulling strong.
