Description

You will receive one (1) cylinder head for your make/model. All TSP heads and inserts now include a complete head gasket kit including inner and out cylinder o-rings and head bolt crush washers. Everything you need to install your new TSP head or insert with all new o-rings and seals.

This CNC machined TSP head suits KTM 85 SX and Husky TC 85 2017+ models. 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 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.
