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.

Climb aboard a true classic. Kick back and enjoy the timeless style that made riding synonymous with freedom. It’s all about the laid-back stance, broad saddle, and that irresistible rumble that only a cruiser can provide.

Features may include:

• 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.
