Two-Stroke Power: Tuned for Enduro

The YZ125X's advanced, liquid-cooled 125cc two-stroke engine utilizes a revised compression ratio, revised YPVS timing and a model-specific digital CDI unit compared to its motocross sibling—all focused on creating a broad, usable power delivery specifically suited to cross country and enduro-style competition.

Lightweight Aluminum Frame

The lightweight, race-proven YZ125-spec aluminum semi-double cradle frame is engineered to provide the perfect balance of rigidity and flex for competition-ready handling character and composure. Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.
