Suzuki M800 Intruder (2010-2019): A Muscle Cruiser Built for the Long Haul

Introduction

The Suzuki M800 Intruder, also known as the Boulevard M50 in some markets, is a mid-sized cruiser that strikes a compelling balance between raw V-twin power, rider-friendly ergonomics, and head-turning design. From 2010 to 2019, this model carved out a niche for riders seeking a machine that feels at home on winding backroads, urban commutes, and weekend getaways. With its liquid-cooled 805cc engine, inverted front forks, and signature "hard-tail" aesthetic, the M800 Intruder isn’t just a motorcycle—it’s a statement. Having spent time aboard a well-maintained 2016 model, I can confidently say this bike rewards riders with a mix of accessibility and excitement that’s rare in its class.

Design: Classic Cruiser Meets Modern Muscle

Visual Appeal

The M800 Intruder’s design is a masterclass in blending classic cruiser DNA with modern aggression. The 45-degree V-Twin engine dominates the frame, finished in black or chrome depending on the year, while the inverted 41mm forks add a sporty contrast to the laid-back silhouette. Key design highlights include:
- Headlight Cowl: Borrowed from Suzuki’s larger M109 series, it gives the bike a focused, predatory stance.
- LED Lighting: The taillight and turn signals are crisp and modern, with a clear-lens LED taillight that complements the bobbed rear fender.
- Color Options: Over the years, Suzuki offered bold schemes like Glass Sparkle Black, Pearl Mira Red, and Metallic Oort Gray, ensuring the bike stands out in a parking lot.

Ergonomics

With a seat height of just 700mm (27.6 inches), the M800 welcomes riders of all sizes. The pullback handlebars and forward-mounted footpegs create a relaxed "rider’s triangle," ideal for hours in the saddle. The wide seat is plush enough for daily use, though aftermarket options (like a solo seat) can enhance the bike’s custom look.

Performance: Torque is the Name of the Game

Engine Character

At the heart of the M800 Intruder lies an 805cc, liquid-cooled V-Twin tuned for low-end grunt. Key specs:
- Power: 53 HP @ 6,000 RPM (38.7 kW)
- Torque: 69 Nm (51 lb-ft) @ 3,200 RPM
- Fuel System: Suzuki’s Dual Throttle Valve (SDTV) injection ensures crisp throttle response.

Twist the throttle, and the engine delivers a satisfying surge from idle, peaking early in the rev range. This isn’t a bike that begs to be redlined—it’s happiest churning out torque between 2,500–4,500 RPM, making it a joy in city traffic or on rolling highways. The 5-speed transmission shifts smoothly, and the shaft drive eliminates chain maintenance while adding a reassuring sense of durability.

Exhaust Note

Suzuki’s custom-styled exhaust delivers a deep, rumbling soundtrack that’s assertive without being obnoxious. For riders craving more bark, aftermarket slip-ons are a popular upgrade.

Handling and Comfort: Confidence on Two Wheels

Chassis and Suspension

The double-cradle steel frame and 1655mm (65.2-inch) wheelbase provide stability at speed, while the inverted front forks and link-type rear suspension (with 7-way preload adjustment) handle bumps with composure. Despite its 269kg (593 lbs) wet weight, the M800 feels surprisingly nimble when leaned into corners, thanks to its low center of gravity.

Braking

The single 300mm front disc brake offers strong initial bite, though the rear drum brake feels underwhelming compared to competitors’ setups. Upgrading to sintered pads or a braided stainless line can sharpen responsiveness.
