Save time and money rebuilding the top end of your motorcycle with a Wossner Piston kit & top end gasket set.

The top end gasket set included in this kit may vary and depend on supplier stock at time of purchase; if stock unavailable at time of purchase, a similar quality branded product will be included instead.

About Wossner Piston Kits

  • All Wossner pistons are forged in-house from aluminum
  • Forging gives the alloy a better grain flow, which in turns creates more tensile strength, or the ability to bend without breaking.
  • All pistons are machined on state-of-the-art CNC machine equipment, then hand finished and inspected for quality.
  • The forged pistons come complete with gudgeon pin, clips, and high-performance rings.
