Description

TSP CNC Cylinder Head for 2025+ KTM/Husky/GasGas 85cc Models

• Complete TSP head (Cap and Insert)
• Complete head gasket kit with inner and outer orings, and 6 copper crush washers
• 2 x base gaskets which are required to be fitted together under the cylinder in order to achieve the necessary cylinder height and correct squish clearance.
• New NGK spark plug and spark plug cap, which is required to run this TSP head.

This CNC machined TSP head is designed for 2025+ KTM SX, Husky TC, and GasGas MC 85cc models. It features an improved combustion chamber design that gives more performance from bottom to top as well as reduced risk of detonation.

The head is designed to work with the supplied 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 ratings.

2025 models MUST run the BR9ECM spark plug and special spark plug cap with this head as the OEM spark plug thread is smaller on the 2025 models.

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.
