Vehicle assignment

The piston is assigned to the Mz 125 SX from the entire 2001-2008 model year range. This vehicle assignment is used to select the appropriate piston for this model and year of manufacture.

Selection note

The specified diameter of 53.94 mm, the oversize letter A, the STD version and the bore diameter of 54.00 mm are particularly important for the assignment. The Race Evolution cast piston is aimed at applications where a 2-stroke piston solution designed for racing is sought for the Mz 125 SX.
