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.
