Cylinder head S3 power fits on GasGas EC 300 TBI 24-

S3 Enduro/MX cylinder head kit made from the finest aluminium for high quality and durability.

Two-piece construction eliminates air pockets commonly found when casting a standard cylinder head.

Thicker combustion chamber walls help absorb heat more consistently and remove it from the coolant more efficiently.

The forged combustion chamber cover has more water volume and is thinner than the original part, making the entire cylinder head lighter than the original part.

Our cylinder heads eliminate the "hot spots" usually found in cast cylinder heads.

All of these features have an effect on cooling properties that protect the engine from overheating and increase component life.

Anodized and laser marked for 100% factory appearance.

Comes with 1 combustion chamber.
