2020 Swm Six Days 440 Technical Analysis & Specification Breakdown
Positioned in Swm's classic motorcycle lineup, the 2020 Swm Six Days 440 pairs a 445.3 cc (27.2 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 29.5 HP (21.5 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 66.2 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
