Right now there’s a bike that offers everything you could have dreamed of…and more! Surf the net and check out the rivals. And you’ll see that nothing in the 125cc class can match what our latest Yamaha YZF-R125 has to offer.

This remarkable motorcycle has been developed using the same advanced technology that makes our larger capacity R-series models some of the most respected bikes on the street and track.

Its radical bodywork is a direct spin off from our World Championship winning R6. And with features like upside down front forks and an aluminium swinging arm - as well as a short-stroke liquid-cooled engine and optional ABS - the latest YZF-R125 is built to thrill.

Ultimate class-leading 125cc supersport
Legendary race-bred R-series DNA
R6-inspired dual headlight fairing
Race-type air intake between headlights
High-rigidity upside down front forks
Multi function LCD instruments
Highly efficient fuel injection system
Lightweight race-bred wheels with Y-shape spokes
High-tech radial front caliper with floating disc
Revised rear suspension linkage for added comfort
Forged aluminium rear brake pedal and shift lever
Available with optional ABS
Liquid-cooled 4-stroke single cylinder engine

Featuring a free-revving short-stroke configuration, the liquid-cooled 125cc 4-stroke engine drives though a slick-shifting 6-speed gearbox to give ultra-responsive acceleration. Equipped with a highly efficient fuel injection system, the latest generation YZF-R125 delivers thrilling performance with outstanding fuel economy.

Lightweight aluminium chassis components

R-Series DNA is evident in the light and immensely strong aluminium swinging arm which ensures precision handling and confident roadholding. A redesigned rear linkage gives even greater riding comfort, and with the brake pedal, shift lever and passenger footrests all made from aluminium, the YZF-R125 has a leading specification.

Multi function LCD instrumentation

The YZF-R125 is equipped with one of the most sophisticated LCD instrument panels seen on a 125cc bike. Its comprehensive backlit display includes a digital speedometer with a bar type tachometer, and the advanced design also includes data on fuel level and fuel consumption, as well as distance and range trip meters.

R6-inspired bodywork

With its aggressive twin headlight fairing and central air intake, there's no mistaking the R-series heritage in the latest YZF-R125. The new generation R6-inspired front cowl gives this class-leading 125cc supersport a genuine big-bike look and feel, and the slippery aerodynamic bodywork is ready to slice through the air for maximum riding excitement.

High-rigidity upside down forks

Just like the legendary R1 and WSS-winning R6, the YZF-R125 is now equipped with upside down front forks which offer high levels of rigidity for precise and responsive handling characteristics. To emphasize the R-series racing heritage the front fender features a carbon-look finish, giving the latest YZF-R125 a real big-bike character.

Lightweight race-bred wheels

Newly-designed lightweight wheels utilize a race-bred multi-spoke design featuring thin Y-shaped spokes that contribute to a low unsprung weight for responsive suspension action and precise handling. And with a 100/80-17 front tyre and wide section 130/70-17 rear tyre, this 125cc superport bike is built to slice though the bends.

High specification brakes with optional ABS

Available with optional ABS, the YZF-R125’s advanced new braking system is a spin off from our larger-capacity R-series models. Featuring a floating 297mm diameter disc, the high specification radially mounted caliper is designed to deliver strong and effective braking performance and outstanding initial response.
