This TSP top end rebuild kit fits KTM SX 85 and Husky TC 85 models from 2018+, as well as the Gas Gas MC 85 2021 model. Image shows the actual piston you will receive, however gaskets are slightly different to the image. You will receive the correct parts for your make/model.

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. Made in Italy and packed especially for TSP. Includes a selection of base gaskets, 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.
  • Pro X little end bearing

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 OEM 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 25 hours on it.
