Positioned in Suzuki's super motard motorcycle lineup, the 2018 Suzuki V-Strom 650XT 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 69 HP (50.4 kW) at 8,000 rpm while maximum torque reaches 69 Nm (50.9 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 107 HP per liter and a 1,600 rpm working window between peak torque (6,400 rpm) and peak power (8,000 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 650XT measures 216 kg (476 lbs) dry, translating to a power-to-weight ratio of 0.32 HP/kg (3.13 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 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 supports practical everyday commuting and weekend road stints, while factory top speed is listed at 185 km/h (115 mph).
