At the heart of the 2007 Suzuki Boulevard M109R custom - cruiser motorcycle, Suzuki relies on a 1783 cc (108.8 cu in) liquid-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 123.4 HP (90.1 kW) at 5,200 rpm while maximum torque reaches 160 Nm (118 lb-ft) at 3,200 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 69.2 HP per liter and a 2,000 rpm working window between peak torque (3,200 rpm) and peak power (5,200 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 M109R measures 347 kg (765 lbs) wet (curb), translating to a power-to-weight ratio of 0.36 HP/kg (2.81 kg per horsepower). Rider ergonomics and chassis geometry center around a 705 mm (27.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,710 mm (67.3 in) wheelbase engineered for planted straight-line stability. The 19.5-liter (5.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
