BBR Motorsports 120cc Big Bore And Cam Kit Honda XR100R / CRF100F 1981-2015 Installation

BBR Motorsports 120cc Big Bore and Cam Kit Honda XR100 / XR100R / CRF100F

BBR Motorsports celebrates one of the best selling dirt bikes of all time with this high-compression 120cc big bore engine kit for the XR/CRF 100. Increased displacement, higher compression and large cooling fins enhance the performance and longevity of the motor. This is the only XR/CRF100 bore kit that matches the new rocker arms perfectly to the new high-performance BBR cam shaft. This kit is ready to go and bolts on with no case boring required. Dyno tests show more than 2HP gain with this kit.

Features: 

  • Increased displacement and higher compression design
  • BBR large fin aluminum cylinder with steel sleeve
  • New rocker arms and adjusters
  • BBR high-performance camshaft and HD valve springs
  • 58mm piston, ring set, pin and clips
  • Gasket kit including cylinder head and cylinder base gaskets
