Engineered by Suzuki for the naked motorcycle segment, the 2021 Suzuki SV650A pairs a 645 cc (39.4 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 75 HP (54.7 kW) at 8,400 rpm while maximum torque reaches 64 Nm (47.2 lb-ft) at 6,400 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 116.3 HP per liter and a 2,000 rpm working window between peak torque (6,400 rpm) and peak power (8,400 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 SV650A measures 198 kg (437 lbs) wet (curb), translating to a power-to-weight ratio of 0.38 HP/kg (2.64 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,445 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 14.5-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
