Engineered by Yamaha for the naked motorcycle segment, the 2011 Yamaha MT-03 utilizes a 660 cc (40.3 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 47.3 HP (34.5 kW) at 6,250 rpm while maximum torque reaches 56.2 Nm (41.5 lb-ft) at 5,730 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 71.7 HP per liter and a 520 rpm working window between peak torque (5,730 rpm) and peak power (6,250 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the MT-03 measures 192.4 kg (424 lbs) wet (curb), translating to a power-to-weight ratio of 0.25 HP/kg (4.07 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
