Schmitt Cylinder Head for Sportfreund 50ccm (38 mm) – with centering for Simson

The Schmitt cylinder head is suitable for the Schmitt Sportfreund cylinder with 50 ccm and 38 mm bore – including centering. Developed as a genuine tuning part with performance increase for your Simson (e.g. Simson S51), this head relies on a manufacturing quality that is rarely found today.

Compared to many replica cylinder heads on the market, this head is manufactured using the aluminum die-casting process, just as in GDR times. As a result, the surface finish is nearly perfect. For better thermal properties, the head is designed slightly larger and has significantly stronger cooling fins – this helps with heat dissipation, especially when you drive your Simson S51 more sportily. Despite the optimized design, the size difference is hardly noticeable when mounted; the original look remains largely preserved.
