CRF250R\'07 - OEM Head w/ Kibblewhite Valves & Springs

Each CRF's Only head is professionally assembled with Kibblewhite stainless steel valves.  Valves seats are cut and a proprietary port to valve seat profiling performed for increased performance using a state-of-the-art NEWEN CNC machine.  This same NEWEN technology is used by top race teams in all of motorsports such as F-1, NASCAR, NHRA etc.  Don't settle for less when the best is so affordable.

  • New OEM 2007 CRF250R head
  • Kibblewhite Stainless Steel Intake valves
  • Kibblewhite Stainless Steel Exhaust valves
  • Kibblewhite seals and spring kit
  • New OEM valve cotters
  • Valves professionally installed
  • Ready to bolt on and ride

OPTIONAL: Header Studs and Head Gasket.  Performance porting service for even more performance from this head.

NOTE: This head fits all years of the CRF250R and CRF250X.  It's a very popular head for both CRF250R and  CRF250X models. It does not have the emissions port so keep this in mind.  With Kibblewhite valves and valve springs this is a performance head with excellent durability. CRF250X owners expect to see up to 4 HP improvement with increased throttle response.
