Engineered by Suzuki for the super motard motorcycle segment, the 2021 Suzuki V-Strom 650A relies on a 645 cc (39.4 cu in) liquid-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 70 HP (51.1 kW) at 8,800 rpm while maximum torque reaches 69 Nm (50.9 lb-ft) at 6,300 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 108.5 HP per liter and a 2,500 rpm working window between peak torque (6,300 rpm) and peak power (8,800 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 V-Strom 650A measures 216 kg (476 lbs) wet (curb), translating to a power-to-weight ratio of 0.32 HP/kg (3.09 kg per horsepower). Rider ergonomics and chassis geometry center around a 835 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,560 mm (61.4 in) wheelbase engineered for planted straight-line stability. The 20-liter (5.3 US gal) fuel tank paired with a rated consumption of 3.5 L/100 km provides an estimated theoretical range of roughly 571 km (355 miles) between fill-ups, while factory top speed is listed at 185 km/h (115 mph).
