Positioned in Yamaha's sport motorcycle lineup, the 2019 Yamaha MT-03 relies on a 321 cc (19.6 cu in) twin, four-stroke powerplant. Internal engine geometry specifies a 11.2:1 compression ratio.
On the scales, the MT-03 measures 168 kg (370 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
Within MotoLibrary's Yamaha archive, this model family spans 17 indexed model years from 2004 to 2025, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
