This TSP top end rebuild kit will suit KTM300EXC/XC and Husky TE300 models from 2008-2016. Images shows parts from the 2017-on 250 kit, however the 08-16 300 kit is basically the same, except it does not come with the rubber spark plug cover and you will receive the correct 300 flat top piston.

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.
