Suzuki Boulevard C90 B.O.S.S. Features and Benefits

Engine Features

The 1462cc (90 cubic inch) long-stroke, liquid cooled, SOHC, 4-valves-per-cylinder, 54 degree V-Twin engine is built to deliver massive torque while maintaining efficient operation

Each aluminum-alloy cylinder is plated 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.

Dual spark plugs for each cylinder contribute combustion and fuel efficiency.

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. The 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.

To further reduce mechanical noise, 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.

An automatic Idle Speed Control (ISC) system improves cold starting and stabilizes engine idle under varying conditions.

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.

Transmission Features
The Suzuki Clutch Assist System (SCAS) reduces the force needed to pull in the clutch lever so clutch operation remains light. The system produces smooth downshifts by reducing pressure on the clutch plates under deceleration.

Low maintenance shaft drive delivers efficient power delivery.

Chassis Features
Design engineers married the desire for time-honored appeal with the need for modern performance. The result is a traditionally styled cruiser featuring a rider triangle – footboards, handlebars, seat position – that delivers classic control with outstanding comfort. Wide handlebar and seat design, plus wide/low fuel tank shape add to C90's low-slung look.

Engineers shaped the seat to allow a rider freedom of movement, not locking them into one position. The seat shape also accommodates riders of different sizes to reach the handlebars and footboards in comfort.

Wide 130/80-17 front and dominant 200/60-16 rear tire are mounted on custom-styled seven spoke cast aluminum wheels

Large floorboard-type footrests are standard equipment for comfortable long range riding

A link-type rear suspension utilizes an oil-damped, coil-over shock to produce a smooth, ground-hugging ride. It’s tucked into the frame well to help keep the ride low, resulting in a Classic hard-tail style appearance.

Additional Features
A large 4.8-gallon fuel tank delivers long riding range for far fewer fuel stops.

Easy to see atop the fuel tank, the C90 B.O.S.S. features a multi-function instrument package highlighted by a large analog speedometer. The package 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. It delivers a level of instrumentation that is not often found on classically style cruisers.
