Yamaha MT-09

The Yamaha MT-09 is a street motorcycle of Yamaha's MT series, powered by a liquid-cooled four-stroke 12-valve DOHC inline-three engine of 847 to 890 cc with a crossplane crankshaft, in a lightweight cast alloy frame. It was sold as the FZ-09 in North America until 2018, when it became the MT-09 in every market. Yamaha product manager Shun Miyazawa said the company weighed parallel twins, inline threes, inline fours and V-twins before choosing the inline three as the best balance of power, torque and weight, and it was Yamaha's first inline-three since the XS750 and XS850 of 1976 to 1981. It competes with the Triumph Street Triple, Kawasaki Z900 and MV Agusta Brutale 800. A 2017 update added adjustable suspension, traction control and ABS, and in October 2020 it received an 890 cc engine. A partly faired sport-touring relative, the Tracer 900, followed in 2015.
