Engineered by Suzuki for the touring motorcycle segment, the 2012 Suzuki Boulevard C109RT features a 1783 cc (108.8 cu in) liquid-cooled v2, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 112.0 x 90.5 mm (4.4 x 3.6 inches) with a 10.5:1 compression ratio.
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 1,755 mm (69.1 in) wheelbase engineered for planted straight-line stability. The 19-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
