2025 Suzuki Boulevard M109R: BOLD AND POWERFUL.
Introducing the 2025 Suzuki Boulevard M109R…
The sleek and muscular 2025 Suzuki Boulevard M109R remains the performance cruiser other bikes wish they were. This M109R has a powerful V-twin engine with two of the largest pistons in the industry – a bike that will get your adrenaline flowing whenever you ride. The imposing 109 cubic inch engine is centered in a streamlined chassis that includes slash-cut mufflers, drag-style bars, a supplied solo seat cowl, and a distinctively shaped headlight nacelle that’s uniquely Suzuki.
The deep Glass Sparkle Black paint is highlighted by deep chrome applied to the edge of the fork-mounted headlight nacelle and through to the imposing dual-muffler exhaust. The M109R is so visually stunning that it draws attention away from everything else on the road. This bike is not just about looks, as a stout inverted fork, a hidden single-shock rear suspension, and an ideally designed saddle deliver responsive handling and an exceptionally comfortable ride. Performance never looked so good, or so bold.
2025 Suzuki Boulevard M109R Totalmotorcycle.com Key Features
• Deep, rich Glass Sparkle Black paint is flawlessly applied the long and purposeful bodywork creating an imposing muscle cruiser that is unlike any other. From the distinctive headlight nacelle to drag-style handlebars and tear-drop fuel tank, the M109R looks even sleeker when the tail cowl is mounted in place of the passenger seat, proving this Boulevard is in a class of one.
• The 109 cubic inch (1783cc), eight-valve, DOHC, 54-degree, liquid-cooled, V-twin produces massive, tractable power and responsive torque. Huge 4.4-inch forged aluminum alloy pistons are two of the largest reciprocating gas engine pistons used in any production passenger car or motorcycle.
• A wide-ratio, constant-mesh five-speed transmission features a tall fifth gear ratio for relaxed highway cruising. The low-maintenance shaft drive is clean-running with minimal torque reaction as it efficiently transmits power to the massive, low-profile 240/40 x 18 rear tire, the widest ever used on a Suzuki motorcycle.
• Like the brakes from a GSX-R1000R, the M109R’s radial-mounted, dual front brakes help deliver sure stopping performance. The beefy, inverted fork and the 240mm wide rear tire give the M109R a tough, aggressive stance and help deliver a smooth, comfortable ride.
• The instrument cluster includes a digital tachometer, gear position indicator, and LED indicator lights integrated into the top of the headlight cowl. The turn signals and taillight feature clear lenses for a modern, custom appearance.

• Suzuki Advanced Sump System (SASS), a compact dry sump lubrication system, reduces engine height, and provides a lower crankshaft position, resulting in 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, further reduces overall engine height, and also contributes to a lower center of gravity.
• A dual spark plug per cylinder ignition system is controlled by a powerful 32-bit ECM, improving combustion efficiency, and reducing 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 two-into-one-into-two stainless steel chrome-finished exhaust system features Suzuki’s digitally controlled SET (Suzuki Exhaust Tuning) system for optimum engine performance and a powerful V-twin sound.
• The sculpted V-twin features polished or chromed engine covers that complement the visually striking cylinders with symmetrical, highlighted cooling fins.
• A wide-ratio, constant-mesh five-speed transmission features a tall 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, wide 18-inch rear tire.
A high-tensile steel, double-cradle frame comfortably manages all the M109R’s power and torque while delivering agile handling and a plush, smooth ride.
• The massive, low-profile 240/40 x 18 is the widest rear tire ever used on a Suzuki motorcycle.
