At the heart of the 2025 SWM Silver Vase T 650 classic motorcycle, SWM features a 644 cc (39.3 cu in) oil & air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 38.9 HP (28.4 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 60.4 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
Rider ergonomics and chassis geometry center around a 900 mm (35.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,444 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
