You will receive one (1) cylinder head insert for your make/model.
This CNC machined TSP head insert suits KTM85SX and Husky TC85 2018 models and fits into the stock cylinder head outer part. It features an improved combustion chamber design that gives more performance throughout the rev range as well as reduced risk of detonation. It has been designed and tested to work with 98 RON fuel and will also suit higher octane FIM spec fuels.
All TSP mods are designed and dyno tested in-house at TSP so you can be sure you’re getting reliable performance for local conditions.
This head insert comes in 2 options:
- Standard Cylinder Height… the head insert is designed to work with the stock base gasket thickness and gives a boost to power throughout the rev range. This option is best suited to novice riders or offroad racers looking for maximum midrange.
- TSP Spec Cylinder Height… the head insert is designed to work with a raised cylinder height and gives maximum mid/top performance. This option is best suited to skilled A or B grade riders. This options includes the required base gaskets to set the correct cylinder height… head gaskets supplied are genuine and you will receive 2 gaskets to use together (KTM RRP on these gaskets is $28.60 each).
