Priced in between the zippy Boulevard M90 and the touring-focused Boulevard C90T, the Boulevard C90 B.O.S.S. hits the “street attitude” target dead center. Its formula for doing so includes blacked-out finishes that cover virtually the entire machine, except for the headlight bezel, turn-signal housings, cam covers, floorboards, foot controls and a few other bits. Power comes from same liquid-cooled 1,462cc V-twin as found in the other Suzuki “90” (90ci) models. While the five-speed gearbox is a gear short of some competitors’ six-speed boxes, the C90 B.O.S.S. punches back with clean, quiet, and nearly maintenance-free shaft drive.
