You will receive one (1) cylinder head insert for your make/model. Please be sure to specify your make/model/year in the Model Validator to ensure proper fitment.
This CNC machined TSP head insert suits KTM 150 SX/XCW and Husky TC 150 2016-2022 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 over-rev, it will be easier on hill climbs, easier to lift the front and faster corner to corner due to the increased torque up to 12,000 rpm.
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 91 octane 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 all conditions.
