2021 Suzuki Boulevard M109R BOSS Cruisers – Features and Price

Engine Features

The 109 cubic inches (1783cc), eight-valve, DOHC, 54-degree, liquid-cooled, V-twin engine is designed to provide a significant amount of tractable power and instantaneous torque.

Huge forged aluminum-alloy pistons measure 4.4 inches (112 mm). These pistons, which have a race-proven design to reduce friction and inertial mass, are among the enormous reciprocating gasoline engine pistons currently being utilized in any production passenger vehicle or motorbike.

For optimal heat transmission, smaller piston-to-cylinder clearances, and lighter construction, Suzuki’s race-proven Suzuki Composite Electrochemical Material (SCEM) is used to line each of the big cylinders. Compact dry sump lubrication system Suzuki Advanced Sump System (SASS) allows for a lower center of gravity, a lower crankshaft position, and a lower engine height. The Suzuki Dual Throttle Valve system (SDTV) with 56mm throttle bodies, which maintains optimum air velocity for smooth soft- to mid-range throttle response, is a critical component of Suzuki’s industry-leading electronic fuel-injection system.

The development of a small cylinder head, a decrease in total engine height, and a lower center of gravity are all made possible by a unique two-stage cam drive system. For increased combustion efficiency and lower exhaust emissions, a robust 32-bit ECM manages a dual spark plug per cylinder ignition system. On each side of the engine are two pleated fabric air cleaner pieces that are part of a three-piece, 9.5-liter airbox (with twin intakes). Suzuki’s digitally controlled SET (Suzuki Exhaust Tuning) system is integrated into the 2-1-2 stainless steel blacked-out exhaust system to optimize engine performance and provide a loud V-twin sound. The visually appealing cylinders with symmetrical, emphasized cooling fins complement the engine’s blacked-out covers.

A high fifth gear ratio for leisurely traveling along the highway is part of a wide-ratio, constant-mesh five-speed gearbox. A low-maintenance shaft drive effectively transfers power to the enormous 18-inch back tire while operating smoothly and with little torque. High-tensile steel twin cradle frame is designed to provide quick handling and a comfortable, smooth ride while comfortably managing all the power and torque. The vast 240/40 x 18 is the giant rear tire ever mounted on a Suzuki motorbike. It has a low profile. Blacked-out, inverted front forks provide 5.1 inches of smooth wheel travel and race-proven cartridge internals with 46mm stanchion tubes. Adjustable spring preload is available to accommodate rider and passenger weight in the cast aluminum alloy swingarm, which utilizes a progressive linkage and a single rear shock absorber. The bike has two completely floating disc brakes up front with dual-piston calipers and one disc brake with a single, dual-piston caliper at the back. The rider/machine interaction is improved by mounting flat-bend, drag-style handlebars on pull-back risers close to the seat, which enhances comfort and control.

The entire 5.2 gallons of petrol are stored in the long-stretch fuel tank (4.9 gallons for the California model).In addition to an LCD odometer, twin trip meters, a fuel gauge, and a clock, the analog speedometer is positioned on the tank. The top of the headlamp cowl integrates an instrument cluster with a digital tachometer, a gear position indicator, and LED indicator lights. The driver’s and the passenger’s seats are highly padded, provide plenty of room for movement, and are designed for comfort. To give the vehicle’s interior an even more aggressive appearance or for use on solo journeys, a sporty solo-seat cover (included) may be swiftly switched for the passenger seat.

This motorbike is simple to manage and enjoyable to ride because of its upright riding posture and mid-mounted foot controls. Midnight Crimson and Vivid Black are the other two hues available. When combined with black powder-coated accents, each of these hues provide a unique appearance. We also particularly like how this motorcycle’s boldly curved exhaust pipe is designed.
