NEW BBR CRF150F (06-Present only) - 195cc Big Bore Kit. High quality bore kit that shows substantial power gains throughout the RPM range. 9.8:1 compression ratio allows use of premium pump gas.
Complete kit includes: cylinder, piston, ring set, pin, clips and gaskets. The 2006 and newer CRF150F may be the greatest playbike on the planet, and now it's easy to big bore it. Our new bore kit starts easily without an exotic battery, or bump starting it, and it flat out rips! The key, though, is it runs great on 92 pump premium. - Duane Brown Always a good time getting out and ripping pit bikes in the woods.
