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.

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.
