4-STROKE RACER'S CHOICE PISTONS
- When blow-by starts to increase on other pistons and power starts to fade, Wiseco Race Series parts continue sealing and performing
- Now you can own the same race parts as all the top race teams
- These high-tech piston designs offer maximum compression ratios, ultra-stiff strutted forgings, and titanium nitride-coated rings, which all add up to more power that is sustained longer
2-STROKE GP SERIES PISTONS
- Have additional features over standard Pro-Lite parts
- Each piston is E-Coated on the crown, ring grooves, and pin bore, for maximum wear resistance and protection from micro-welding, galling, and detonation
- Additionally, boost ports are removed for a more predictable powerband and increased pull on the top end
- GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression
