Overview
The 2026 Yamaha MT-03 is a naked motorcycle in a model family produced from 2011 to 2026. Its 321.0 cm³ liquid-cooled, four-stroke parallel twin makes 42 hp (31 kW) and 29.6 Nm of torque at 9,000 rpm; at 169.2 kg wet, it has a manageable amount of mass to move around.
The 780 mm seat height can make it easier to get a foot down at stops, while the 14-liter tank provides an estimated range of about 333 km at 4.20 liters/100 km. The engine’s torque peak at 9,000 rpm means you need to rev it to reach its strongest pull. ABS works at both ends, and the rear shock’s seven-step preload adjustment lets you adapt it to changes in rider or load.
