Sharp bodywork and bold graphics
The YZ125 2-stroke features modern bodywork and graphics for a lean look. The fenders and fork protectors give a sharp image, while the side covers and seat cover highlight a fresh look.
48mm upside down forks
The 48mm upside down front forks are similar to the design used on our YZ-F 4-strokes, and feature a separate air/oil system that prevents air from entering the cartridge for more stable damping. The forks run with special YZ125-specific settings, and give even lighter and more agile handling characteristics.
Monocross rear suspension system
As well as the forks, the YZ125 is also equipped with a Monocross rear suspension system consisting of a redesigned swingarm, shock and linkage taken from the YZ-F 4-stroke bikes. This system offers outstanding shock absorption characteristics together with good traction for holeshot-winning performance.
Wide footrests and clutch adjuster
The YZ125 2-stroke benefits from a range of features that have come straight from our latest YZ-F 4-stroke models. The wide footrests give additional support for a perfect feeling of control during aggressive riding – and there’s also a clutch adjuster for easy tool-free adjustments to cable slack.
125cc 2-stroke engine
At the heart of this hard-charging lightweight is a free-revving 124cc, liquid-cooled, 2-stroke engine equipped with Yamaha’s renowned YPVS system for increased power. Driving through a close-ratio, 6-speed transmission, this super-compact and easy-to-maintain engine can be tuned with our YRRD kit parts for even more winning performance.
High-agility, ultra-light chassis
The compact, 125cc, 2-stroke engine is fitted into a semi-double cradle aluminium frame that is both light and strong, and which delivers a balance of rigidity that gives high levels of rider feedback. With a wet weight of just 94kg, the YZ125 is one of the easiest dirt bikes to flick through bends and power over washboard sections.
