Description
This CNC machined TSP head insert fits KTM/Husky/Gas Gas 300 TBI Models 2024-on.
The models include:
- KTM 300 XC-W 2024-on
- Husky TE 300 2024-on
- Gas Gas EC 300 2024-on
This listing does not fit SX/XC/TX/EX Models as they require different head inserts. Please see our other listings for these models.
You will receive one (1) cylinder head insert for your make/model, and a cylinder head o-ring and washer kit so you can bolt it straight on.
The TSP insert can be used in conjunction with the TSP Cap as a complete head, or you can use this insert inside your stock cap.
TSP insert features are:
- Drastically improved throttle response in the whole RPM range
- Smoother throttle response
- Much better part throttle power
- Much more enjoyable to ride
TSP Insert options are as follows:
- MEDIUM COMP – this insert suits the majority of trail riders and hard enduro racers who want better bottom and mid power and a small gain up top as well. The power delivery is much stronger and more tractable than stock but still super smooth and suits a wide range of riding conditions. Works with 91 octane fuel.
- HIGH COMP – this insert suits riders who want harder hitting power everywhere, especially down low. It completely transforms the TBI into a trail weapon. This insert may push the limits of normal 91 octane pump fuel at sea level under certain extreme conditions, but it can be used in normal trail riding conditions safely in order to achieve maximum bottom/mid performance. This insert can be used at elevations above 3,500′ to approximately replicate a medium compression insert at sea level.
TSP heads/inserts work very well when used together with an ECU reflash completing the package, and it is highly recommended doing an ECU tune at the same time to get the best results.
All TSP mods are designed and dyno tested in-house at TSP so you can be sure you’re getting reliable performance and a quality product.

I am a terrible mechanic and I was able to get this and the TSP power valve cover done in about an hour. Not as noticable change to low end as the ERM, but well worth it. Would definitely recommend TSP and of course South Bay!!
