Harley-Davidson’s most powerful cruiser motorcycle is the Sportster S. It is powered by a fully built-in liquid-cooled 1,252cc V-twin that produces 121 horsepower and 93 pound-feet of torque. These are impressive numbers for a $15,999 cruiser bike. However, the $15,799 Suzuki Boulevard M109R undercuts the Harley in value, while also packing more punch with its noticeably beefier V-twin.

Suzuki Boulevard M109R vs. top US rivals

A gigantic V-Twin powers the Suzuki M109R

Power: 128 hp

The big twins on American cruiser motorcycles are a great source of inspiration for the 1,784 cc V-twin on the Suzuki Boulevard M109R. However, the inspiration is only limited to the size and appearance, as the M109R’s liquid-cooled mill has many cool and unexpected features. The main reason this nearly twenty-year-old engine is still so powerful is its sportsbike-derived internals. Yes, this big bustling V-twin has many internal and technological features derived from Gixxer liter-class sports bikes of the early 2000s. It features an eight-valve, short-stroke design, allowing this heavyweight cruiser to rev to 7,500 rpm – an exceptional performance for a low-slung cruiser of this size.

Peak power is almost 130 ponies

It produces 128 horsepower and 118 pound-feet of torque at 6,200 rpm and 3,200 rpm, respectively. The early torque surge helps propel this ‘heavy’ Suzuki with ease. Plus, thanks to its relatively high peak power revs, the 750-plus-pound Suzuki still impresses with a top speed of 125 mph. For reference, the 549-pound Indian 101 Scout has an identical top speed figure. Power is sent to the rear wheel via a widely distributed 5-speed gearbox and a low-maintenance shaft drive.

Robust foundation to carry the power of the M109R with conviction

Chassis: double cradle frame

The M109R Boulevard cruiser bike is based on a steel frame with a double cradle with high tensile strength. It is supported by fat 46mm upside-down forks at the front and a monoshock at the rear. The front offers 5.1 inches of travel and the preload-adjustable rear shock offers 4.7 inches. A rear monoshock with more than 43.5 inches of travel is a standout feature, especially for a cruiser bike that weighs more than 750 pounds. For reference, the 2025 Harley Street Bob, despite weighing more than 100 pounds less, offers only 3.4 inches of rear suspension travel.

GSX-R-derived brakes help the M109R stop

On the hardware front, parts shared by Gixxer are also present. The M109R shares the dual front brakes with the 1,000cc GSX-R sports bikes. It boasts of dual 310mm discs at the front and a single 274mm disc at the rear. The fat 130-section front and 240-section rear tires wrapped around 18-inch alloy wheels enhance driving dynamics, stability and intimidating visual appeal. The rear tire size is still the widest of any production-spec cruiser bike, with the mighty Triumph Rocket 3 Storm also boasting 240-section rear rubber.

Custom-inspired styling that makes it a certified head-turner

This is one of the few modern classics that have nailed the design front, with a timeless appeal. This Suzuki’s road presence is huge, with an expansive stance and plenty of shiny chrome components. Furthermore, Suzuki designed the M109R to be bold and muscular. Every body panel on this mighty cruiser bike blends together, offering a beautiful blend of curves and aggression. All the while, a 67.4-inch wheelbase makes it longer than the most stretched Harley-Davidson of today: the 66.7-inch Breakout.

The single sinister black paint job, combined with components such as the chunky front fork shrouds, tires, wide fenders and a forward-protruding headlight design, come together to maintain its classic yet muscular visual appearance. The V-twin engine and the elongated two-on-two exhaust system in chrome provide a harmonious contrast to the entire setup. The most iconic visual element of this Suzuki cruiser bike is its side profile. The smooth and uninterrupted silhouette strongly reminds us of another curvy but intimidating Suzuki: the Hayabusa.
