• Description

  The MotoSport.com Wiseco Pro-Lite Piston Kit - 2-Stroke includes one of each of the following components with the following attributes:

  The Wiseco Piston Kit is not just a basic piston replacement, it is a performance piston kit that is more durable than O.E.M. pistons and includes everything necessary to rebuild your top end.

  Wiseco Pro-Lite Piston:

  Important note:

  This piston is for a stock sized bore. Please measure your cylinder to check clearance before ordering.

  Wiseco leads the performance aftermarket by producing the highest quality forged pistons in the U.S.A. Wiseco is unique because they forge all of their own pistons in-house, and produce all of their own forge tooling in the U.S.A. This allows Wiseco to control all aspects of their manufacturing process from raw bar to skirt coating on the finished parts.

  Wiseco Pro-Lite motorcycle pistons are forged using the highest quality materials available resulting in a piston that provides excellent performance and durability. The Wiseco Pro-Lite piston features a race-ready dome finish with smooth edges for improved combustion flow. The rings, wrist pin, and circlips are manufactured by Wiseco under their strict quality standards to make sure every piston kit fits correctly, ensuring top performance is achieved.

  Pro-Lite Piston features:

  • Much stronger than stock.
  • Tight tolerances for quiet running.
  • More hours with peak performance between piston changes.
  • All Pro-Lite pistons include rings, wrist pin and circlips.

  Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.

  Wiseco Needle Bearing:

  The Wiseco Needle Bearing is a high quality replacement wrist pin bearing designed to withstand the harsh demands of racing. Wiseco built their needle bearing to meet or exceed O.E.M. specifications.

  Cometic Top End Gasket Kit:

  State-of-the-art gaskets is what Cometic has been doing since its inception in 1989. This comes from their dedication to constructing gaskets for the most demanding race circuits like AMA and NASCAR. Today's lightweight engines are producing more horsepower, higher cylinder pressure, clamp load and extreme temperatures. Cometic's commitment is to provide innovative, quality gaskets while maximizing your engine's power and performance.

  Cometic meets the needs of each specific gasket by using materials to match. Even the basic top end gasket kit features different materials for each gasket. The head gasket is constructed from non-asbestos, flexible graphite that is laminated to a stainless steel core. The manifold and base gaskets are constructed from non-asbestos nitride rubber-bound fiber. Cometic also includes copper gaskets where needed.

  Cometic designs and builds their gaskets in the U.S.A.
