New 125cc engine with VVA system
The new YZF-R125 engine uses an innovative new Variable Valve Actuation system that optimizes the valve position for higher levels of low rpm torque and stronger high rpm power – and also improves fuel efficiency. A wider diameter throttle body gives a smoother and more controllable throttle feel – and the new exhaust system produces a sporty and emotive sound.
Improved combustion efficiency
To achieve higher levels of intake efficiency the YZF-R125s new engine is equipped with larger intake and exhaust valves as well as a more compact combustion chamber. Combined with the high-tech VVA – as well as the larger throttle body and new exhaust system – this configuration offers more performance from a stand still through to top speed.
Refined Deltabox frame
The YZF-R125 is known as one of the best-handling bikes in its category, and for even smoother and lighter handling – with improved high speed comfort – the refined Deltabox frame uses optimized front and rear geometry. Equipped with a new shorter aluminium swingarm and 41mm upside down forks, the new YZF-R125 brings you the ultimate 125 supersport specification.

Improved A&S (Assist & Slipper) clutch
To help you take full advantage of the increased engine performance, the new YZF-R125 is equipped with an improved A&S clutch that gives a lighter feel at the lever for more precise operation and increased controllability. The new design ensures smooth and efficient acceleration; and during deceleration the A&S clutch helps to prevent rear wheel lock ups.
New R-Series LED twin-eye body design
Inspired by the iconic YZF-R1, the confident and aggressively styled face features twin-eye LED headlights that reinforce the R-Series family connection. Its M1 MotoGP style front fairing underlines the race-bred specification, and with a 12 LED taillight and premium finish, there’s no mistaking the pure R-Series DNA in the YZF-R125’s stunning new bodywork.
Newly designed 11-litre fuel tank

New high-visibility LCD instruments
When you turn on the new YZF-R125 you’ll be greeted with a personal greeting from the high-tech instruments – and once you’re moving the new multi-function display gives you information on gear position and shift timing, as well as a VVA indicator. Housed in a stylish and sporty panel, these high-visibility instruments keep you informed.
Sporty and comfortable riding position
As well as its new race-bred YZR-M1 style cockpit, the YZF-R125 is also equipped with a newly designed rider and passenger seat featuring a revised shape and thicker foam for increased comfort.

Offering a good balance of grip and durability, this supersport style tyre is designed to enable you to optimize the potential of the new engine’s wider spread of power, and its wide-section accentuates the bike’s aggressive R-Series stance.
Refined and improved braking feeling
Equipped with a large diameter 292mm front disc and a 230mm rear disc, the YZF-R125 is built to give you outstanding braking performance – and for 2019 this state-of-the-art braking system benefits from a revised brake hose layout and a new rear caliper that contribute towards a better brake feel for precise and accurate control.
