Positioned in Suzuki's custom - cruiser motorcycle lineup, the 2018 Suzuki Boulevard M90 pairs a 1462 cc (89.2 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 79 HP (57.7 kW) at 4,800 rpm while maximum torque reaches 131 Nm (96.6 lb-ft) at 2,600 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 54 HP per liter and a 2,200 rpm working window between peak torque (2,600 rpm) and peak power (4,800 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Boulevard M90 measures 328 kg (723 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.15 kg per horsepower). Rider ergonomics and chassis geometry center around a 716 mm (28.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,690 mm (66.5 in) wheelbase engineered for planted straight-line stability. The 18.2-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
