Built around Suzuki's custom - cruiser motorcycle platform, the 2005 Suzuki Boulevard M50 utilizes a 819.4 cc (50 cu in) liquid-cooled v2, four-stroke layout. In factory specification, 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. Internal engine geometry specifies a bore and stroke of 83.0 x 74.4 mm (3.3 x 2.9 inches) with a 9.4:1 compression ratio.
On the scales, the Boulevard M50 measures 269 kg (593 lbs) wet (curb). 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.
