This billet cap and CNC machined TSP head insert fits 2023+ KTM and Husky 125 models with the new 125 TBI (Throttle Body Injection) engine. The TSP head is designed to work with the supplied TSP base gasket and gives a big boost to power throughout the rev range.
You will receive one (1) cylinder head & insert for your make/model, a raised base gasket and a cylinder head o-ring and washer kit so you can bolt it straight on!
The key TSP Head features are:
- Improved throttle performance in the whole RPM range
- Smoother throttle response
- Improved combustion chamber design that gives more performance from bottom to top
- Reduced risk of detonation
If you are deciding between our head/insert or an ECU flash, it is advised that you go for our ECU tune first. The ECU flash will enable larger gains than this head/insert by itself as the TSP ECU maps improve fuel, ignition and power valve maps. There are gains to be made by just swapping the head/insert especially with additional smoothness, but this is best complimented with the ECU flash so you get the most out of the head design. Fitting our ECU Flash and Insert/Head at the same time will offer much better performance gains over stock.
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.
