S3 Star Cylinder Heads

 S3 Star Cylinder Heads

The S3 cylinder heads are machined from billet aluminium. S3 Star Heads are a stunning looking, top quality component.
Made in 2 parts using the best alloys available on the market, to obtain better power output.
The advantage of these heads is that they hold more water, and the material is a lot thicker. This helps with cooling and improves low down power.

STAR HEADS eliminate the hot points typically localized on cast heads.

The different volume inserts gives the possibility to adjust perfectly the engine compression. You can change the inserts for lower or higher compression (using the same outer part) and these are available separately. Ready to fit. Anodised. S3 Laser logo.

High compression (A-Red colour).
Standard compression (STD-Silver colour).
Low compression (B-Gold colour).

S3 Star heads available for Gas Gas TXT PRO 125/250/280/300, and the Sherco 250/290.Coming soon Beta EVO
