Honda CRF110 Race Head - CJR Performance

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. 

CJR Performance Stock Valve Race Head -
Recommended for stock bore up to 147cc big bore kits. Depending on the camshaft, expect to retain good low RPM performance with a strong increase in mid-high rpm power and more available overrev.
- Improved Polished Combustion Chamber Design
- Eliminate Valve shroud for increased flow
- Ported/Polished intake and exhaust port with removed guides for increased flow
- 22mm Intake Port to allow use of 24mm and 26mm Throttle Body Kits
- 22mm Exhaust Port to pair with smaller and larger exhaust systems 
- Upgraded HD Valve Springs safe to 12,000rpm (11,000rpm recommended for most exhaust, 12k+ only with a larger 30-34mm throttle body, high lift cam, and large exhaust (yoshimura/rocket big bore)
- Machined Spring Seat to allow the largest camshaft profiles available
- Stock valve size to improve low end response and increase long term reliability, OEM replacement valves available at any Honda dealer
