Streetfighter looks with supersport technology

Using the YZF-R125 platform as the starting point, our engineers have created a whole new kind of motorcycle that is the first ever streetfighter in the 125cc class. Featuring an all-new naked chassis with a dynamic mass-forward look, the MT-125 is all about pure riding emotion.

Like our larger capacity MT models, the new MT-125 is a sporty and agile bike that loves to be ridden every day of the week. The new tank, seat, handlebars and footrests give a sporty riding position for good rider and passenger comfort - while the frame geometry and ergonomics ensure easy manoeuvrability in urban riding.

With its naked chassis, lightweight race-style wheels and athletic styling, the strong MT family DNA can be seen throughout this new bike - while its low angular headlight and high-shouldered air intakes present an imposing front view.

Upside down forks with high-tech brakes

The advanced upside down front forks give smooth and progressive suspension with responsive roadholding - and to underline its technological advantage the MT-125 A is fitted with ABS and features a 292mm diameter floating front disc brake and radial mount caliper for excellent feel and effective stopping power.

Lightweight race-style wheels

The MT-125's race-style wheels feature six sets of thin Y-shaped spokes that keep the unsprung weight low for responsive suspension action and a smooth ride. At the front a 100/80-17 tyre gives confident roadholding, while a wide section 130/70-17 rear tyre delivers high levels of traction and underlines the uncompromising streetfighter image.

High-tech cockpit area

The full LED instrument panel greets the rider when turned on, and includes bar style displays for rpm, engine temperature and fuel level, as well as a shift light and digital speedometer.
