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.

• EZ clips free of charge (worth $29.95) for ease of piston installation. Please note these only suit our Meteor pistons, OEM and Vertex. It may also suit pistons with a 1.5mm wire clip

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. All TSP rebuild kits are kept in stock at TSP.

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 100 hours of engine run time and use a B size over 100 hours of engine run time. Its ALWAYS better to have a bit too much clearance than not enough, so if in doubt use an A size.
