Description

This TSP top end rebuild kit fits KTM SX 85 and Husky TC 85 models from 2018 onwards, 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:

• Piston kit in size B.   (A piston kits available through special order) Piston kit includes rings, pin, clips and a high quality cast piston with anti-friction coating. These pistons are made by Meteor in Italy and are THE BEST available.
• 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.

Piston sizing: ideally you should measure your bore with a dial gauge to work out the correct piston sizing. If you cannot do this then a rough rule of thumb is use an A size under 50 hours of engine run time and use a B size over 50 hours of engine run time.
