Potent Twin-Cylinder Powerplant Yamaha’s 321cc liquid-cooled, inline 2-cylinder engine delivers excellent power and performance throughout the rpm range. With a 180-degree crank design and integrated counterbalancer, the layout minimizes vibrations for a smooth, refined engine character.
Smooth and Useable Power With double overhead cams (DOHC) and four-valve cylinder heads, the MT-03 engine provides easy to manage power at low rpm with strong high rpm power —ultimately delivering an exciting ride with a broad spread of power.
Six-Speed Transmission A smooth-shifting six-speed gearbox ensures the rider always has the right ratio, whether riding through tight city streets or on the open highway.
Modern Fuel Injection Downdraft induction fuel injection system provides easy starting, excellent fuel economy, and responsive performance in all conditions.
Advanced Cylinder Construction Yamaha’s unique DiASil —a high-silicon aluminum alloy —is used in the cylinders to ensure excellent heat dissipation. An innovative offset cylinder design helps reduce friction and provides better efficiency, quicker response and great overall engine performance.
Strong and Lightweight Forged Pistons Forged aluminum pistons —the same technology used in the MT-10 — contributes to reduced power loss and lower vibration levels. This design results in minimized vibrations and smooth running, even at high rpm.
Compact Exhaust System The short muffler design features modern styling and helps to centralize mass, improving agility for ultra-responsive handling.
