Unleash your build with the new CRF110F Race Head! 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 head 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.
