R and R Racing Cylinder Heads for 2 Stroke Bikes

The RR cylinderhead is a two part assembly.  The housing section, which holds a combustion chamber and the combustion chamber, is interchangeable and therefore makes it very easy to change the characteristics of your engine and setup your engine for different types of circuits.

Combustion chambers are available in a range of types for each model, can be ordered blank, or made to specification. Special chamber models can be made. And being made out of special aluminum, extremes can be sought,as the possibility of detonation is being reduced.

 Over the years R and R Racing deveopment team have tested flow simulation and strenght analisys on the RR cylinderheads and have improved the cooling capacityand the strength of the cylinderheads.

The RR Race Cylinder Head is available for the following bikes:
