CRF125F BIG VALVE RACE HEAD (CUSTOM ORDER)

Turnaround time is about 20-30 business days after receiving your core. 30-60 business days for new 

Unleash your build with the new CRF125F Race Head! One of the biggest restrictions with the 19+ CRF125 is the intake and exhaust port along with the OEM valves and 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 and top end power that keeps pulling strong when paired with a DCR or TB camshaft.

for purchasing cores, you may choose to send your head in before or after with a refund of $150 if you choose after once we receive your OEM head

CRF125F custom big valve race heads are now available for pre-order!!! You are required to send in your OEM cylinder head with your order number if selecting core!

We use TB parts, big valves and custom ported and polished intake and exhaust chambers on a new OEM head. During this time, a standalone Aracer ECU is required working on flashes with CJR in the near future!
