Factory 2.R Cylinderhead KTM SX50 – Husqvarna TC50 – GasGas MC50

RR-racing cylinder head for the KTM, Husqvarna & GasGas 50cc has been developed in house to obtain a smoother running engine developing more power whilst staying cool. This is reached by creating a unique combustion chamber shape for the KTM SX50, more power and better delivery, that combined with the unique RR-racing coolant flow technology inside the head the heat is transferred away better and easier.
