CJR Performance Race Head - CRF110

CJR Race Head comes updated for a big improvement in low-mid range performance with added combustion chamber work, revised port shape, and more!

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. 

This cylinder head comes updated with new features and is fully assembled (Excludes rocker arms/tappets)
