Cylinder head S3 (300cc) 19-21

S3 cylinder head kit Enduro/MX manufactured from the highest quality aluminum to achieve high quality and long durability.
The two-part design eliminates air inclusions that normally occur when casting a standard cylinder head.
Thicker combustion chamber walls help to absorb heat more consistently and to be carried away more efficiently by the coolant.
The forged combustion chamber cover has a higher water volume and is thinner than the original part, making the entire cylinder head lighter than the OEM cylinder head.  Cylinder heads eliminate the "hotspots" that are normally found in cast cylinder heads.
All these properties affect the cooling performance, which protects the engine from overheating and thus increases the longevity of the components.
Anodized and laser-marked for a 100% factory look.

Extreme version: Reduced engine compression – results in very smooth throttle response, ideal for slippery conditions. Easier motorcycle control and longer service intervals. 

Power version: Higher engine compression – results in significantly increased power and more aggressive engine characteristics. Preferably for motocross use. 

Included in the delivery:
1 forged cylinder head cover
1 combustion chamber
5 O-rings for cylinder head cover and combustion chamber

Only suitable for Beta RR 2T Sport Enduros (300cc) from 2019 to 2021
