About this product

Engineered and developed by BBR. This cylinder retains skid plate mounts and includes: BBR aluminum cylinder, piston kit, and gaskets. Custom piston designed specifically for the OEM Honda XR/CRF70 cylinder head . The most reliable kit available. Runs great with stock carb or bolt on BBR's 18mm carb kit.


  • Cylinder retains skid plate mounts
  • BBR aluminum cylinder
  • 52mm piston specially designed to work with your stock cylinder head's combustion chamber
  • Gasket kit

Note: Do not use this bore kit with the OEM Honda XR/CRF50 cylinder head. This piston dome is too tall and will hit causing damage to your engine. Use our bore kit intended for that cylinder head: Bore Kit - 88cc W/Cam / XR/CRF50, 00-Present
