S3 star head for Gas Gas Pro

 S3 Star Cylinder Heads
These new 'STAR' cylinder heads from S3 are an affordable and easy way for customers to change and personally setup the compression of the Gas Gas PRO models. As with all S3 products they are superbly engineered. Available are inserts for different conditions, low, standard and high compression inserts to fit the S3 STAR heads. The basic rule is this.....if you want a fairly flat power for beginners or really slippy conditions than you would set the bike up with a low compression insert. If you wanted a more aggressive power setup or you are going high in altitude then go with higher compressions. S3 Star heads available for PRO 125/250/280/300.
