It includes:

  • Meteor piston kit in the size of your choice (A or B). Piston kit includes rings, pin, circlips and a high quality cast piston. These pistons are made by Meteor in Italy and are THE BEST available. The new Meteor piston features a special coating on the crown to reduce temps of the incoming charge and reduce detonation. This is a cutting edge piston developed especially for KTM.
  • Top end gasket kit.  Includes two gaskets to achieve the stock 0.60mm thickness base gasket, power valve cover gaskets, copper washers and O rings. All O rings are the correct size and made from the correct material, unlike the cheaper aftermarket kits.
  • TSP little end bearing
  • EZ clips free of charge for ease of piston installation

TSP rebuild kits are put together by TSP using parts sourced direct from OEM manufacturers in Japan and Europe. The parts we select are THE BEST available for each make/model and many are the exact same parts as the genuine items.

We typically recommend only using an “A” piston size for brand new cylinders or cylinders that have been replated. The “B” piston size is typically used for any cylinder that has more than 50 hours on it.
