Inspired by the legendary YZF-R1 and developed with pure R-Series DNA, the YZF-R125 is engineered to give you instant power with exceptional control.

The YZF-R125 engine is the most sophisticated 125cc design we’ve ever built. Its Variable Valve Actuation system and high-flow cylinder head deliver strong low rpm torque with exciting high rpm power – giving quick acceleration, fast pick up, a high top speed and outstanding fuel efficiency.

The aggressive YZF-R1-derived bodywork and dual LED headlights project a strong and forceful look – and the compact Deltabox frame together with an aluminium swingarm and wide 140-section rear tyre confirm the YZF-R125’s status as the ultimate lightweight supersport.

Excellent combustion

To achieve high levels of intake efficiency the YZF-R125s engine is equipped with larger intake and exhaust valves as well as a compact combustion chamber. Combined with the high-tech VVA – as well as the larger throttle body and sport exhaust system – this configuration produces impressive acceleration

Sporty and comfortable
riding position

As well as its 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.

Wide 140-section
rear tyre

To confirm its strong R-series DNA the YZF-R125 runs with a wide 140/70-17 rear tyre that gives excellent stability and confident cornering. Offering a good balance of grip and durability, this supersport style tyre is designed to enable you to optimise the potential of the engine’s wide spread of power, and its wide-section accentuates the bike’s aggressive R-series stance.

A&S (Assist & Slipper)

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.

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


Delivering smooth and light handling characteristics as well as excellent high-speed comfort, the YZF-R125 is one of the best-handling bikes in its category. Its Deltabox frame uses optimum front and rear geometry as well as a short aluminium swingarm and 41mm upside down forks to give you the ultimate 125 supersport chassis specification.

Lightweight aluminium

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.

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.

High-visibility LCD

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.
