Yamaha MT-09

The motorcycle that changed everything has evolved into an even sharper and more technologically advanced Hyper Naked – and this dynamic MT-09 is built to inspire today’s generation of thrill seeking riders like no other bike in its class.

First impressions are everything – and with its intimidating LED twin-eye face, the aggressively styled MT-09 demands attention. The front winglets and radiator side fins give an ultra-sharp look – and to reinforce the bike’s uncompromising style we’ve designed a shorter tail.

With its radical looks, refined bodywork and higher specification, this unstoppable force is ready to take your Hyper Naked riding experience to the next level.

Power

Liquid-cooled 4-stroke, 850cc in-line 3-cylinder fuel-injected engine with a downdraft intake. The engine has been tuned to provide plenty of low to mid-range torque with strong yet linear throttle response.

Brakes

ABS equipped brakes feature dual 298 mm discs with 4-piston calipers up front and a 245 mm disc with single piston caliper in the rear providing peace of mind while braking under pressure or in wet conditions.

Style

The MT-09 features an aggressively styled twin-eye headlight assembly that gives this best-selling naked sport a more menacing look. The slanting dual headlights are equipped with four LED bulbs, accompanied by dual LED positioning lights.
