Wiseco GP Piston

Racers Choice pistons are packed with performance enhancements. These cutting edge designs produce the maximum power possible out of each application, designed to keep you at the front of the pack. Most Racers Choice pistons are single ring 2-stroke or two ring 4-stroke pistons. With one less ring, weight and friction are reduced, power is increased, and throttle response is instantaneous! Racers Choice pistons offer extra performance to those racers and engine builders who want the most in every race. Two Stroke GP Series pistons have additional features over standard Pro-Lite parts. Each piston is electrocoated on the crown, ring grooves, and pin bore, for maximum wear resistance and protection from micro-welding, galling, and detonation. GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression. Additionally, boost ports are removed for a more predictable power band and increased pull on the top end.
