Engineered by Suzuki for the custom - cruiser motorcycle segment, the 2006 Suzuki Boulevard M50 relies on a 805 cc (49.1 cu in) liquid-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 50 HP (36.5 kW) at 6,500 rpm while maximum torque reaches 65 Nm (47.9 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 62.1 HP per liter and a 1,500 rpm working window between peak torque (5,000 rpm) and peak power (6,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Boulevard M50 measures 247 kg (545 lbs) dry, translating to a power-to-weight ratio of 0.2 HP/kg (4.94 kg per horsepower). Rider ergonomics and chassis geometry center around a 700 mm (27.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,655 mm (65.2 in) wheelbase engineered for planted straight-line stability. The 15.5-liter (4.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
