  • Racer Elite 2-Stroke pistons are forged out of a 2000 series alloy that offers more tensile strength than the more popular 4000 series. Pistons are coated with ArmorPlating, a Wiseco surface treatment covering the crown, ring groove, pin bore, and under-crown.
  • ArmorPlating protects against wear caused by heat and detonation. ArmorFit skirt coating adapts to the proper piston-to-wall clearance during initial operation, and remains at that clearance, reducing operating friction throughout the life of the piston.
  • A unique benefit of having ArmorFit on a 2-stroke piston is the ability to eliminate the need for A, B, C piston sizing.
  • R&D developed
  • Dyno proven power gains


Racer Elite 4-Stroke pistons feature an asymmetrical skirt design that keeps contact with the cylinder wall minimal, as well as keeps the weight down. They also feature ArmorGlide skirt coating, ensuring friction is staying as low as possible. Racer Elite 4-stroke pistons are fully machined billet, allowing for the best weight optimization and the ability to machine the boxed under-crown structure with precision.
