Agility. Ability. Victory.

Which is where the YZ125 comes in. With its explosive engine power and ultra responsive aluminium chassis, this lightweight 125cc 2-stroke is a proven winner at the highest level.

This legendary dirt bike with its ultra responsive front and rear suspension systems for agile handling and fast cornering – and its sharp bodywork gives a cool factory look. Now all that’s missing from the package is…you.


  • YZ-F type Monocross rear suspension system
  • Fast-action clutch adjuster mechanism
  • Wider footrests for increased controllability
  • 2-stroke engine technology for easier maintenance
  • Easy to adjust 38mm Keihin carburettor
  • Wide range of genuine accessories available
  • Free-revving and compact 125cc, 2-stroke engine
  • Ultra-light, semi-double cradle aluminium frame
  • Race-winning power with lightweight handling
  • YZ-F type 48mm forks, separate air/oil function
  • Modern bodywork for a lean and sharp image
  • YRRD (Yamaha Rinaldi R & D) tuning kit available


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 a light and agile handling characteristic.

The new YZ125 is equipped with a smooth Monocross rear suspension system consisting of a swingarm, shock and linkage taken from the YZ-F 4-stroke bikes. This system offers outstanding shock absorption characteristics together with good traction for class-leading performance.

The YZ125 2-stroke features modern bodywork and graphics that give a lean and fresh look. The fenders and fork protectors give a sharp image, while the side covers and seat cover underline the fresh look – and to underline the ‘factory bike’ style we’ve fitted the air scoops with new graphics.

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.

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 and control during aggressive riding – and there’s also a modern clutch adjuster for easy tool-free adjustments to cable slack.

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.



Nothing compares to the YZ125 experience. When the gate drops its powerful 125cc 2-stroke engine is built to be revved hard and fast through the 6-speed gearbox. And at just 94kg wet, the speed and agility of this hardcore race bike is ready to take your breath away.
