2019 Suzuki Boulevard C90 B.O.S.S.

Chassis Features

• The appeal of classic styling is combined with the bene?ts of modern performance, with the steel-tube frame comfortably carrying the rider and con?dently housing the powerful engine.
• The styling incorporates a muscle cruiser visual statement: rich paintwork, blacked out suspension and chassis components plus deep front and rear fenders with flared ends.
• Additional cruiser-friendly features include well-positioned footboards, 4.8-gallon fuel tank and shaft drive.
• Design engineers focused on creating an ideal rider’s triangle – footboards, handlebars and seat positions set to deliver classic control with outstanding comfort.
• Both rider and passenger seats are made for comfort and top-notch control. They allow freedom of movement, accommodate riders of different sizes, and are well cushioned.
• Wide passenger seat makes for comfortable two-up rides. It’s stepped location on the rear fender allows passengers to see over the rider’s shoulder.
• The design of the link-type rear suspension maintains classic hard-tail look, while keeping the ride low and producing a smooth, ground-hugging ride.
• Stout telescopic front forks deliver generous 5.1 inches of smooth wheel travel and the long 65.9-inch wheelbase provides a smooth, comfortable ride.
• A beefy 16 inches rear tire and complementary 17 inches front tire have wide foot-prints and are mounted to black, cast-style wheels for a power cruiser look.
• Hydraulic front and rear disc brakes provide strong, reliable braking performance.
• The multi-function instrument includes a convenient gear-position indicator and a fuel gauge, along with a clock and a trip meter, plus indicator lights for low fuel, turn signals and more.
• Bright multi-reflector headlight. Durable, efficient and compact LED taillight and four bullet-style turn signals.

Engine Features

• Liquid-cooled, 90 cubic inch (1,462cc) long-stroke V-twin engine delivers the most power and torque in the 1,000 to 1,600cc class. Outstanding low-to-mid range output means smooth acceleration and comfortable long-range cruising characteristics.
• Sculpted engine features blacked-out engine and air cleaner covers that complement the visually striking cylinders with symmetrical cooling fins.
• The aluminum-alloy cylinders are coated with Suzuki Composite Electrochemical Material (SCEM), a coating of nickel-phosphorus-silicon-carbide that reduces friction and increases heat transfer. The result is increased durability and ring seal.
• Each piston’s upper compression ring and oil control ring are given a chrome-nitride coating to make them harder and smoother to further reduce friction.
• Four-valve cylinder heads with overhead camshafts and dual spark plugs increase combustion efficiency to help ensure seamless throttle response, gutsy low- to mid-range output, better fuel efficiency, and reduced emissions.
• To further reduce mechanical sounds, each cylinder head’s cam cover is separated from the cam bearing caps, and a rubber gasket is used between the cylinder head and the cam cover.
• Suzuki Dual Throttle Valve (SDTV) induction system is enhanced by the 32-bit engine control unit that instantly delivers the optimum fuel-air mixture and power output. This system – it’s the same design used in Suzuki championship-winning GSX-R sportbikes – delivers seamless throttle response while boosting fuel efficiency and delivering strong torque.
• Auto Fast Idle System (AFIS) automatically sets the throttle valve opening during cold engine starts by monitoring coolant temperature.
• To maximize air induction for best power and torque, the C90 features a unique system that uses three separate air-cleaner boxes feeding the engine. This air induction system increases engine output without sacrificing style or fuel tank capacity.
• The Suzuki Clutch Assist System (SCAS) reduces the force needed to pull in the clutch lever, so clutch operation remains light. The clutch features back torque limiting clutch system, contributing to smooth downshift operation.
• Blacked-out, dual-exhaust system mounted on the right side of the engine is tuned for responsive torque delivery providing a deep, rumbling exhaust note.
• A wide-ratio five-speed transmission features a high fifth gear ratio for relaxed highway cruising.
• Low-maintenance shaft drive is clean-running and has minimal torque reaction as it efficiently transmits power to the wide 16-inch rear tire.

Key Features

• New Metallic Gleam Gray or Glass Sparkle Black colors and complementary graphics combine with the Blacked Out Special Suzuki (B.O.S.S.) styling to create a visually stunning cruiser that lives up to its looks by delivering a great ride.
• Ninety cubic inch (1462cc), 54-degree, V-twin engine rumbles through dual pipes as it smoothly puts down power that’s at home in town or out on the highway.
• With a light pull, the clutch feeds engine power to the smooth-shifting five-speed transmission and out to the clean shaft drive.
• Riders settle in behind wide, buckhorn-style handlebars, with feet comfortably on forward-mount floorboards, while sitting on a plush seat that’s just 28.3 inches above the ground.
• The classically styled 4.8-gallon fuel tank complements the large valance fenders that hover over the wide 16-inch rear and 17-inch front tires mounted on cast aluminum wheels.
• Brushed, stainless steel covers shield the stout front fork whereas a hidden, link-style rear shock smooths the ride while giving the bike an old-school, hard-tail look.

Other Features

• 12-month limited warranty. Longer coverage periods with other benefits available through Suzuki Extended Protection (SEP).
