Engineered by Suzuki for the custom - cruiser motorcycle segment, the 2005 Suzuki Boulevard S40 utilizes a 655.5 cc (40 cu in) air-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 94.0 x 94.0 mm (3.7 x 3.7 inches) with a 8.5:1 compression ratio.
On the scales, the Boulevard S40 measures 160 kg (353 lbs) dry. 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 1,480 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 10.5-liter (2.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
