38 mm cylinder with round slotted 12 mm intake for Sachs 2-, 3- and 4-speed engines with blower, which were installed on Hercules 50/ALS, 50/2 S, 50/KS, 50/2 DK, 50/3 LS, 50/4 LKS, Gritzner etc., among others.
The smaller cooling fins make it easier to fit the cylinder kit to a Swiss Sachs 50/2 (502) engine, as the blower cover can be fitted without any adjustments. However, adjustments in the area of the stud bolt holes are essential.
