product description
S3 cylinder head kit Enduro / MX made of the highest quality aluminum in order to achieve high quality and long durability. The two-part design eliminates air pockets that normally occur when casting from the standard cylinder head. Thicker walls of the combustion chamber help the heat to be absorbed more consistently and to be transported 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 original part.
The S3 cylinder heads eliminate the "hotspots" that are normally found in cast cylinder heads. All of these properties have an effect on 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.
Low Compression (LOW COMP Gold): Reduced engine compression results in very fine throttle response, ideal for slippery conditions. Easier control of the motorcycle and longer service intervals. Ideal for X-tremendous Enduro, TOP pilots use this.
