70th Anniversary Edition special livery

The YZ125 70th Anniversary Edition sports a special white and red livery inspired by Yamaha’s racing DNA spirit of innovation and continuous challenge for new victories that make this the most desirable 125cc 2-stroke.

Updated intake system

The complete intake system has been updated. The air lter’s intake has been enlarged and reshaped to allow air through more smoothly and the joints have been updated for a smoother connection to the carburettor. All carburettor settings have been optimised for balanced fuel ow at all throttle openings. And ignition timing has been updated for optimal combustion at every degree of throttle opening.

Most powerful YZ125 engine

The high-tech 125cc 2-stroke engine is the most powerful unit ever used on the YZ125. Equipped with Yamaha's famous YPVS (Yamaha Power Valve System) that gives instant response and excellent useability across the rpm range and featuring lightweight race-bred internals it's destined to take you to the victorYZone!

Ultra-slim bodywork

The latest generation bodywork is ultra slim with the area between the rider's knees the narrowest it's ever been on a YZ125 and this athletic and modern design underlines the bike's lightness and compactness. These slim dimensions give a high level of rider mobility and reinforce this lightweight racer's feeling of agility.

Keihin Powerjet carburettor

The YZ125 is equipped with a Keihin PWK 38.1mm carburettor featuring a solenoid controlled powerjet for even more explosive performance – giving a real advantage out of the gate and when accelerating hard out of corners. A TPS (Throttle Position Sensor) and 3D map controlled CDI ensure optimised ignition timing, while the V-Force reed valve assembly ensures optimum intake efficiency at all engine speeds. The 2026 YZ125 allows riders to adjust carburettor settings with greater ease making the machine even more adaptable and user.

Smooth shifting 6-speed transmission

Every second counts, and for reduced lap times the YZ125 runs with a super-smooth shifting 6-speed transmission that enables you to accelerate efficiently and stay out in front. Transmission ratios have been carefully chosen by Yamaha's engineers to maximize race performance and power output in all conditions.
