Built around BSA's classic motorcycle platform, the 2025 BSA Scrambler 650 features a 652 cc liquid-cooled-cooled four stroke, single- cylinder, dohc, 4 valves, twin spark plugs configuration. In factory specification, peak output is rated at 45 HP (33 kW) at 6,000 rpm while maximum torque reaches 55 Nm at 4,000 rpm, transferring power to the rear wheel through a 5 speed gearbox and chain final drive. With a specific output of 69 HP per liter and a 2,000 rpm working window between peak torque (4,000 rpm) and peak power (6,000 rpm), 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 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,463 mm (57.6 in) wheelbase engineered for balanced agility and highway composure. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
