Factory 2.R Cylinderhead KTM SX150 – Husqvarna TC150 – GasGas MC150

Now it’s getting serious. Moving up to the 150cc we are in need of power to compete in the strong field. From novice to pro RR has developed a cylinderhead for the KTM SX150 that can give either a strong bottom end or a long pulling engine satisfying all rider needs. The various inserts developed are the main reason for the differences in power delivery. The unique water flow inside the head creates a very homogenous cooling of the insert transferring the heat quick. Another benefit of the unique water flow inside the RR Cylinderhead KTM SX150 is the lower flow resistance giving the water pump an easier job.
