Tuning head CR 85, 03-07Article number: A-2221-A Special cylinderheads are developed and made by rr-racing. The cylinderheads are machined out of billet aluminium, with some great features. One of them being its excellent heat conductive capacity, which reduces the possibility of detonation, improving the heat flow and therefore making ore possible with the cylinderhead.
The cylinderhead is also dividable into a insert (combustion chamber) and a housing section.
In this way it becomes incredibly easy to fine tune your engine to suit every track.
Our development team succeeded to even improve over the years the cooling capacity of the cylinderhead by increading and perfecting the coolant flow through the cylinderhead. Next to that they’ve increased the strength of the housing section making it very rigid and unaffected by pressure inside the engine.
Cylinderheads are available for all modern 2 stroke bikes.
