BBR introduces the first complete big bore kit for the CRF80 (and XR80)! Our new bore kit includes the cylinder making for a quick and easy upgrade. It features a 52 mm high compression piston resulting in a displacement of 95.6 cc. This kit includes the head gasket, base gasket, and intake gasket. 10.0:1 compression ratio lets it run on pump premium gas. As for all BBR bore kits, we recommend using ethanol free gasoline (seewww.pure-gas.org).
Works with stock camshaft and valve springs or optional BBR performance camshaft (part number 411-HXR-1020 listed in Optional Parts below). OEM Kehin PC18/20 carb works great with minor re-jetting.
