2025 Suzuki Boulevard M109R

The 109 cubic inch (1783cc), eight-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 some of the largest reciprocating gasoline engine pistons being used in any production passenger car or motorcycle while featuring a race-proven design to reduce friction and inertial mass.

Each of the large cylinders is lined with Suzuki's race proven Suzuki Composite Electrochemical Material (SCEM) 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 two-into-one-into-two chrome-finished stainless steel 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 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 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 steel double cradle frame is built to comfortably handle all the 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.

Black 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 5.2 gallons of fuel (4.9 gallons for California model).

The tank-mounted analog speedometer also features an LCD odometer, dual trip meters, a fuel gauge, and a 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, accommodate riders of different sizes, and are well cushioned.

A sporty solo-seat cowling (included) can be quickly swapped for the passenger seat for an even more aggressive look or for use on solo rides.
