Schmitt „Sportfreund“ Racing Cylinder 60ccm (41mm) – powerful torque boost in original look

With the Schmitt „Sportfreund“ aluminum cylinder, you get a modern, high-torque 60ccm 4-port cylinder for your Simson setup – manufactured in Europe and made for reliable performance. Despite modern technology, the appearance remains pleasantly discreet: modern port geometry packaged in a 50ccm original look>.

Thanks to the nickel-carbide-silicon coated cylinder liner, you get a very durable running surface designed for the long term. Additionally, the cylinder offers more surface area for improved cooling. Very practical for tuners: the construction is designed so that you can further machine the cylinder without the need for cumbersome gluing or welding.

Suitable for Simson mopeds/mokicks such as the Simson S51, Simson SR50, and the Simson Schwalbe KR51/2 – ideal if you want more pull in your Simson S51 without running a „conspicuous” look.
