At the heart of the 2024 Yamaha R3 sport motorcycle, Yamaha pairs a 321 cc (19.6 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 41.4 HP (30.2 kW) at 10,750 rpm while maximum torque reaches 29.5 Nm (21.8 lb-ft) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 129 HP per liter and a 1,750 rpm working window between peak torque (9,000 rpm) and peak power (10,750 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the R3 measures 169 kg (373 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.08 kg per horsepower). 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 paired with a rated consumption of 4.1 L/100 km provides an estimated theoretical range of roughly 341 km (212 miles) between fill-ups.
