Re-Define Your Reality

The new YZF-R125 engine is the most sophisticated 125cc design we’ve ever built. Its new Variable Valve Actuation system and new high-flow cylinder head deliver stronger low rpm torque and more high rpm power – giving quicker acceleration, faster pick up, a higher top speed and better fuel efficiency.

Aggressive new YZF-R1-derived bodywork and dual LED headlights project a strong and forceful look – and the refined Deltabox frame together with a new aluminium swingarm and wider 140-section rear tyre reaffirm the new YZF-R125 as the ultimate lightweight supersport

FEATURES

New 125cc engine with VVA system

The new YZF-R125 engine uses an innovative new Variable Valve Actuation system that optimises 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 optimised 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..

Newly designed aluminium swingarm

Yamaha R-Series models are designed to give you the ultimate in style, performance and technology, and to underline its position as the premium 125 supersport, the new YZF-R125 features a new aluminium swingarm. Manufactured using Yamaha’s advanced casting technology, its shorter dimensions, low weight and optimised rigidity deliver sporty handling performance.

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

The YZF-R125’s aggressive race-bred bodywork is complemented by a newly designed fuel tank that emphasises the bike’s pure supersport pedigree. Consisting of a steel inner tank protected by lightweight close-fitting external covers with a high-quality finish, the new 11-litre tank is designed to be easily removed for routine maintenance.

MotoGP-inspired YZR-M1 type cockpit

Everything about the new YZF-R125 is designed to give the ultimate sporty experience. Inspired by Yamaha’s MotoGP bike, the racy cockpit features a new high quality handlebar crown as well as a high-visibility LED instrument panel and brake lever protector that put you in total control on the track and on the street.

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. With an optimised handlebar position and new aluminium rear set footrests, the refined ergonomics give a balanced riding experience that's both sporty and comfortable.

Wider 140-section rear tyre

For 2019 the new YZF-R125 runs with a new wider 140/70-17 rear tyre that gives improved stability and better handling. Offering a good balance of grip and durability, this supersport style tyre is designed to enable you to optimise 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.
