2017 Suzuki Boulevard M109R B.O.S.S.
This is the performance cruiser other bikes wish they were. The dark and muscular M109R B.O.S.S. has a powerful V-twin engine using some of the largest pistons in the industry — a bike that will get your adrenaline flowing whenever you ride. This 109 cubic-inch engine is wrapped with aggressive blacked-out styling that includes slash-cut mufflers, drag-style bars, a supplied solo seat cowl, and a distinctively shaped headlight nacelle that’s uniquely Suzuki. This bike is not just about looks as stout inverted forks, a hidden single-shock rear suspension, and an ideally designed saddle delivers responsive handling and an exceptionally comfortable ride. Performance never looked so good, or so dark.
- A 1783cc, 8-valve DOHC, 54-degree, liquid-cooled, V-Twin engine is designed to produce a massive tractable power and responsive torque.
- Huge 4.4 inch (112mm) forged aluminum-alloy pistons. These are one of the largest reciprocating gasoline engine pistons being used in any production passenger car or motorcycle, while featuring race-proven design to reduce friction and inertial mass.
- Each large cylinder bore is lined with Suzuki's race proven SCEM (Suzuki Composite Electrochemical Material) for optimum heat transfer, tighter piston-to-cylinder clearances and reduced weight.
- Suzuki Advanced Sump System (SASS), a compact dry sump lubrication system, provides reduced engine height, a lower crankshaft position and a lower center of gravity.
- Suzuki's class-leading electronic fuel injection system features the Suzuki Dual Throttle Valve system (SDTV) with 56mm throttle bodies, which maintains optimum air velocity for smooth low to mid-range throttle response.
- A unique two-stage cam drive system creates a compact cylinder head design, reduces overall engine height and creates a lower center of gravity.
- A dual spark plug per cylinder ignition system is controlled by a powerful 32-bit ECM for improved combustion efficiency and reduced exhaust emissions.
- A three-piece, 9.5-liter volume airbox (with dual intakes) includes two pleated fabric air cleaner elements located on both sides of the engine.
- The 2-into-1-into-2 stainless steel blacked-out exhaust system features Suzuki's digitally controlled SET (Suzuki Exhaust Tuning) system for optimum engine performance and a powerful V-Twin sound.
- Sculpted engine features blacked out engine covers that complement the visually striking cylinders with symmetrical, high-lighted cooling fins.
- A wide-ratio, constant-mesh 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 massive 18-inch rear tire.
- A high-tensile double cradle steel frame is built to comfortably handle all the power and torque while delivering agile handling and a plush, smooth ride.
- The massive 240/40 x 18 is the widest rear tire ever used on a Suzuki motorcycle.
- Blacked-out, inverted front forks feature race-proven cartridge internals with 46mm stanchion tubes and provide 5.1-inches of smooth wheel travel.
- Cast aluminum-alloy swingarm works with a progressive linkage and a single rear shock absorber; adjustable spring preload to suit rider and passenger weight.
- Twin front fully-floating disc-brakes with dual-piston calipers and a single-disc, rear brake with a single dual-piston caliper are ready to haul the bike down from speed.
- Flat-bend, drag-style handlebars are mounted on pull-back risers to be positioned within a short distance from the seat to improve the rider/machine interface, aiding comfort and control.
- The long-stretch fuel tank holds a full 4.9 gallons of fuel.
- Tank-mounted analog speedometer and LCD odometer, dual tripmeters, fuel gauge and clock.
- Instrument cluster including a digital tachometer, gear position indicator and LED indicator lights is integrated into the top of the headlight cowl.
- Both rider and passenger seats are made for comfort as they allow freedom of movement and accommodate riders of di?erent sizes, and are well cushioned.
- A sporty solo-seat cover (included) can be quickly swapped for the passenger seat for an even more aggressive look or for use on solo rides.
- The M109R B.O.S.S. (Blacked Out Special Suzuki) features the following: Blacked-out exhaust system, clutch cover, magneto cover, cylinder head covers, air cleaner cover and final drive case; Blacked-out handlebars, clutch and brake levers, handlebar switch cases, rear view mirrors, fuel tank/instrument cover, front and rear wheels, front and rear brake calipers, frame side covers, rear fender stays, side-stand, steering stem clamps and front forks; Clear taillight and turn signal lenses.
