Description
Description
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 (see www.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.

Came timely works well good product
Excellent product, easy assembly. Huge difference in power.
Excellent customer service
Super easy to install. Absolutely dunks on 125cc Chinese pitbikes.
Excellent quality. Prompt shipping. Good communication with vendor. Goid price.
Probably one of the best big bore kits I have installed. Feels like it makes double the power. I added the cam and it allows it to just keep screaming. Well done BBR!
