Notes:
The racing cylinder is primarily used on the Sachs 50/3 and 50/4 engines. Thanks to the large cooling fins, it can also be used in an air-cooled configuration on the Sachs 50/2 (DE) engine.
The cylinder is equipped with a large square intake port for a 17 mm carburetor and a large M40 exhaust thread. Please take this into account when selecting your additional components. Please observe the installation direction during assembly. The piston is installed with the arrow pointing toward the exhaust on the exhaust side.
You can find the matching cylinder head, mounting hardware, exhaust systems, and threadlocker in the accessories section.
