Description
A worn or damaged piston directly compromises engine compression, throttle response, and overall power output—especially critical in high-demand trail and racing conditions. The Wiseco 2379M07850 restores lost performance with a purpose-built assembly that handles the thermal and mechanical stresses of aggressive riding. This complete kit eliminates the need for sourcing rings and circlips separately, getting your MX-Z 670 back to peak efficiency faster.
