S3 Cylinder Head - GasGas Pro 250/280/300cc - 2014 to 2022 (+2013 Factory)

S3 Cylinder Head. Machined from billet or forged aluminium and are absolutely beautiful. Made in 2 parts using the best alloys available on the market, to obtain better output. The advantage of these heads is that they hold more water and also the material is a lot thicker which helps with cooling which improves low down power slightly. Eliminate the hot points typically localised 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). Ready to fit. Anodised. S3 Laser logo

If you want fairly flat power for beginners or for really slippery conditions then you would set the bike up with a "low" compression insert. If you want to keep the bike standard, order the "standard" insert. If you wanted a more aggressive power setup, or you are going high in altitude then you could experiment with a "high" compression insert
