Moto Guzzi MGX-21 (2016–2021): A Bold Italian Bagger with Soul

Introduction

The Moto Guzzi MGX-21, affectionately dubbed the "Flying Fortress," is not your average bagger. Produced between 2016 and 2021, this Italian cruiser defies conventions with its audacious design, transverse V-twin heartbeat, and a blend of retro charm and cutting-edge technology. Built on the California 1400 platform, the MGX-21 carves its own niche in the cruiser segment, offering a distinctly European flavor to riders who crave character and long-haul comfort. After spending a day piloting this machine, it’s clear: this isn’t just a motorcycle—it’s a statement.

Design & Aesthetics: Futuristic Meets Functional

The MGX-21’s design is a head-turner. Its aggressive "batwing" fairing, sculpted with aerodynamic intent, gives it a fighter-jet profile. The carbon fiber accents—front fender, tank panels, and saddlebags—add a touch of motorsport flair while shaving weight. The 21-inch front wheel (a rarity in cruisers) dominates the stance, complemented by a chunky 180/60-16 rear tire. Moto Guzzi’s signature 90° transverse V-twin engine is proudly displayed, its chrome covers glinting against the matte black finish.

The attention to detail is Italian to the core: LED lighting, metal switchgear, and a minimalist dashboard that prioritizes function over clutter. The saddlebags, integrated seamlessly into the design, offer 50 liters of storage—enough for weekend getaways. While the MGX-21’s aesthetic won’t appeal to traditionalists, it’s a masterclass in balancing form and function.

Engine & Performance: Torque is the Name of the Game

At the heart of the MGX-21 lies Moto Guzzi’s 1,380 cc air/oil-cooled V-twin, a powerhouse that delivers 121 Nm (89.2 lb-ft) of torque at 3,000 RPM—enough to pull stumps. The engine’s character is unmistakably Guzzi: a deep, syncopated rumble at idle that smooths into a resonant growl under acceleration.

Twist the throttle, and the MGX-21 surges forward with urgency, thanks to its ride-by-wire system and three riding modes (Turismo, Veloce, and Pioggia). The 6-speed gearbox is clunky at low speeds but finds its rhythm on open roads. Shaft drive eliminates chain maintenance, though it introduces slight driveline lash during abrupt throttle changes.

Fuel economy sits at 6.6 L/100 km (35.6 mpg), translating to a 320 km (200 mi) range from its 20.5-liter tank—a practical figure for touring.

Handling & Ride: Surprisingly Agile for a Fortress

Weighing 356 kg (784 lbs) wet, the MGX-21 isn’t light, but its low center of gravity and 1,700 mm (66.9-inch) wheelbase inspire confidence. The 21-inch front wheel tracks predictably, while the adjustable rear shocks absorb bumps without wallowing.

Lean into a corner, and the bike holds its line with poise, defying its cruiser DNA. The Brembo brakes—dual 320 mm discs up front and a 282 mm rear—offer strong, linear stopping power, though the ABS can feel intrusive during spirited riding.

The 740 mm (29.1-inch) seat is plush for rider and passenger, but the forward-set footpegs might strain taller riders on long hauls. Wind protection from the fairing is excellent at highway speeds, reducing fatigue on multi-hour rides.

Technology & Features: A Modern Cruiser

The MGX-21’s tech suite rivals premium touring bikes:
- Traction Control (3 levels): Adjustable or disable it for rear-wheel theatrics.
- Cruise Control: A godsend on straight highways.
- Bluetooth Connectivity: Pair your phone for music or navigation via the monochrome LCD dash (dated but functional).
- LED Lighting: The headlight’s beam pattern illuminates dark roads confidently.

The hydraulic clutch is heavy in traffic, and the infotainment system feels archaic compared to touchscreen rivals. Still, the essentials are here—and they work.

Competition: How Does It Stack Up?

The MGX-21’s closest rivals include:

1. Harley-Davidson Street Glide

• Pros: Iconic styling, vast aftermarket, smoother Milwaukee-Eight engine.
• Cons: Higher price, less torque, belt drive requires more maintenance.
• Verdict: The Harley excels in brand cachet, but the Guzzi offers fresher tech and a more engaging ride.

2. Indian Chieftain

• Pros: Thunder Stroke 111 engine, superior infotainment, plush seating.
• Cons: Heavier, less agile, pricier.
• Verdict: The Chieftain is a luxury liner; the MGX-21 is the sportier, quirkier alternative.

3. Honda Gold Wing

• Pros: Silky-smooth flat-six, unmatched comfort, advanced features.
• Cons: More touring-focused, less character.
• Verdict: The Gold Wing is a tech marvel, but the Guzzi’s soul is irreplaceable.

MGX-21’s Edge: Its transverse V-twin delivers torque everywhere, and the shaft drive suits riders who despise chain maintenance. The design polarizes—but that’s the point.

Maintenance: Keeping the Fortress Airborne

The MGX-21 is built for longevity, but attention to detail is key:

Final Verdict: Who Should Buy It?

The Moto Guzzi MGX-21 isn’t for everyone. It’s a cruiser that rewards riders who value personality over polish.
