Cylinder retains skid plate mounts
BBR aluminum cylinder
52mm piston specially designed to work with your stock cylinder head's combustion chamber
MX-grind camshaft
Gasket kit
Easy bolt-on instructions included
Installation Note: This kit will not work with the Honda XR/CRF70 or other big port cylinder heads. It is designed for the tiny combustion chamber of the OEM Honda XR/CRF50 cylinder head. The flat top piston dome will result in an extremely low compression ratio when combined with the XR/CRF70 type cylinder head. The result is a motor that makes less horsepower than stock. This is the correct BBR bore kit for the XR/CRF70 .
