At the heart of the 2023 Swm Six6 500 allround motorcycle, Swm features a 445 cc (27.2 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 29.5 HP (21.5 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 66.3 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Six6 500 measures 153 kg (337 lbs) dry, translating to a power-to-weight ratio of 0.19 HP/kg (5.19 kg per horsepower). Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
