Description

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. 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 insert can only be used with the TSP head. It is not interchangeable with other heads. If you do not have a TSP head, please see the TSP head category on our web site. the TSP insert features an improved combustion chamber design that gives more performance from bottom to top as well as reduced risk of detonation.

The TSP head inserts come in different compression ratios, and are designed to be interchangeable for different riding conditions and elevation changes to suit any riders needs.

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.

LOW COMPRESSION (XC-W/XC/SX, TE/TX/TC and MC models): This new Low comp design provides a very smooth power delivery suited for extreme hard enduro, or for riders are looking for a very soft and linear power delivery without a hit. The low comp head does allow the engine to rev up very quickly and the over rev is impressive.  Best for riders who don’t have much need for extra bottom end power. It is a slightly higher comp ratio than the stock XCW/TE enduro heads and it is suited to the enduro models only.

MEDIUM COMPRESSION (XC-W/XC/SX, TE/TX/TC and MC models): The new Med comp design is the new “Go-To” head for most 250 riders. It is the best all-round design for the majority of enduro riders from 0-4,000 ft elevation. It can also be used on the SX/TC models where the motors are revving very hard and require smooth mid-range power gains and lots of over-rev. Higher compression ratio than stock but still works fine with 91 octane fuel. Gives a very noticeable increase in power throughout the rev range, especially bottom/mid. Gives much smoother power delivery than stock. Squish clearance is much tighter than stock.

HIGH COMPRESSION (suits SX and TC models): The new High comp design is best suited for the SX/TC models.  It can also be used on the enduro models at altitude above 5,000 ft.  Works fine with 91 octane fuel at higher elevations.  Squish clearance is much tighter than stock with an improved dome design. Provides impressive power increase everywhere, especially in the bottom and mid range, but still produces a much smoother power delivery than stock.
