Lightweight, quick and easy to maintain, the YZ125 is a perfect transition bike for those too big for 85's but too small or inexperienced for bigger, more powerful four-strokes.
Power: Liquid-cooled, 124 cc, crankcase-reed-valve-inducted two-stroke engine provides class-leading power and acceleration. It's easy to service, too!
Performance: Ceramic composite cylinder bore is a liner-less design with the ceramic coating sprayed directly on the aluminum block. The benefits include reduced weight (no heavy iron liner), reduced friction, extended cylinder life and excellent heat dissipation for consistent power delivery.
