Description:
The Trail Bikes (TB Parts) V2 Race head has numerous advantages over the stock head. Starting with the addition of forged aluminum roller rocker arms and our V2-2 camshaft. Not only do the aluminum roller rockers free up big horsepower, but you can also run much more aggressive cam profiles with roller rockers for even more power. Next is the bigger valves 30mm intake and 24.5mm Exhaust. The intake and exhaust ports are equally as improved at 27/23mm. Both valves are stainless steel too (21-4N material). The valves also come installed, complete with high lift heavy duty valve springs. This all adds up to a cylinder head that puts out a professional level of performance and power yet is still affordable for the privateer rider.
