This kit from 50 Caliber Racing is to upgrade the cylinder head on stock YX/GPX 150 or 160 engines to our new Race Head V2. The addition of this new head will dramatically increase the performance of your stock engine! The addition of roller rocker arms and a new camshaft are the biggest changes followed by bigger valves and ports. The exhaust valve is now stainless as well (21-4N material). This all adds up to a cylinder head that puts out a professional level of performance yet is still affordable for the privateer rider.
