The WISECO forged piston is an original part designed for motocross use, intended for restorations and engine overhauls of vintage trails and motocross bikes. Machined from forged aluminum, it provides the mechanical strength necessary to withstand the cyclic stresses of two-stroke/four-stroke engines (depending on installation), while maintaining a controlled weight for smooth operation of the moving assembly.
Designed for standard installation or as a replacement during an engine rebuild, this WISECO piston meets the specified tolerances and fits compatible cylinders of the same size. Recommended for the motocross environment, it is suitable for vintage models such as the KAWASAKI KX 250 (KX250G 1989, KX250F 1988, KX250E 1987) and other machines accepting the indicated size. Please check compatibility with your cylinder and piston ring kit before installation.
