You will receive one (1) cylinder head insert for your make/model. If you want the complete head, please see the listing for the complete 150 Head.
This CNC machined TSP head insert suits KTM150SX/XC-W and Husky TC/TE150 2016-on models and fits into the stock cylinder head outer part. It features an improved combustion chamber design that gives more performance from bottom to top as well as reduced risk of detonation. Although it signs off slightly earlier in the overrev it will be easier on hill climbs, easier to lift the front and faster corner to corner due to the increased torque up to 12,000rpm.
The head insert is designed to work with the stock base gasket thickness and gives a big boost to power throughout the rev range. 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.
