Complete 38 mm aluminum tuning cylinder with nickel-silicon carbide coating (colloquially known as Nikasil) and square inlet for small engine wheels with Sachs 3- and 4-speed engines with foot shift. These engines were installed on Hercules 50/3 LS 50/4 LKH, Gritzner etc.
The workmanship of the 50 cc racing cylinder is fine, but could do with some rework on some edges.
In order to be able to mount this racing kit on a Sachs 50/2 engine, various adjustments must be made.
