Kitaco 145cc DOHC Bore Kit - XR100R CRF100F NSF100 [MM-1380] $2,599.95USD 

Top of the line double overhead cam bore and stroke kit for the XR100R CRF100F and NSF100 bikes from Kitaco Engineering. Dual 21mm intake valves and dual 18mm exhaust valves provide more flow than any 2 valve head on the market. Kitaco 57mm DOHC piston combined with their 56.5mm crankshaft makes this 145cc kit an absolute beast for torque and horsepower. Pistons and valve buckets are WPC + MOS2 treated for superior strength and ultimate reduction in friction. All of Kitaco's best in one complete kit for the Honda XR100R CRF100F and NSF100 (yes they fit without fairing or frame mods)!

  • Cam specs at 1mm:
  • IN Open 15/ Close 40
  • EX Open 40/ Close 20
NOTE: The DOHC head is slightly longer than oem and SE-Pro heads, and may interfere with the frame on NSF100 models. Frame modification will be required.
