Impressive Power. Engineered and developed by BBR. This cylinder retains skid plate mounts and includes: BBR aluminum cylinder, piston kit, exclusive BBR motocross-grind camshaft and gasket kit. Easy bolt-on instructions included. 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
• 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.
