Benelli Imperiale 400 (2021-2022): A Retro Charm with Modern Sensibilities

The Benelli Imperiale 400 is a motorcycle that doesn’t just ride—it performs nostalgia. Designed as a retro-modern all-rounder, this Italian-inspired (but Chinese-built) machine bridges the gap between classic aesthetics and modern reliability. With its thumping single-cylinder engine, spoked wheels, and upright riding posture, it’s a love letter to motorcycling’s golden era. But does it hold up in today’s world of high-tech expectations? Let’s dive in.

Design & Aesthetics: Timeless, Not Trendy

The Imperiale 400’s design is unapologetically retro. From its teardrop fuel tank to the rounded headlight and chrome-accented fenders, it channels the spirit of 1950s British motorcycles. The 2021-2022 models come in understated color options like black, silver, and red, with finishes that prioritize simplicity over flashiness.

Build Quality: The steel double-cradle frame feels robust, though some welds and panel gaps hint at cost-cutting typical of budget-friendly bikes. The 19-inch front and 18-inch rear spoked wheels add authenticity but demand regular maintenance to prevent rust in humid climates.

Ergonomics: With a 780 mm (30.7-inch) seat height, the Imperiale is accessible to riders of all statures. The wide, padded seat and upright handlebars create a relaxed riding triangle, perfect for city commutes or leisurely weekend rides. At 200 kg (440 lbs), it’s heavier than competitors like the Royal Enfield Classic 350, but the weight stays low, making it manageable at slow speeds.

Engine & Performance: Old-School Thump Meets Modern Fuel Injection

The heart of the Imperiale 400 is its 373.5 cc air-cooled single-cylinder engine, producing 20.8 HP @ 5,500 RPM and 29 Nm (21.4 lb-ft) of torque @ 3,500 RPM. These numbers won’t set records, but they’re delivered with character.

On the Road:
- Low-End Grunt: The torque-heavy engine shines in city traffic. From standstill to 60 km/h (37 mph), the Imperiale feels eager, aided by a light clutch and smooth 5-speed gearbox.
- Highway Limitations: Above 90 km/h (56 mph), vibrations creep through the handlebars and pegs. The engine’s 8.5:1 compression ratio and air cooling mean it’s happiest cruising at 70-80 km/h (43-50 mph).
- Fuel Efficiency: At 3.2 L/100 km (73.5 mpg), it’s frugal. The 12-liter tank (3.17 gallons) offers a 350+ km (217-mile) range—ideal for touring.

Sound & Feel: The exhaust note is muted at idle but develops a satisfying burble under acceleration. The ECU-controlled fuel injection (Delphi MT05) ensures crisp throttle response, though purists might miss the drama of a carburetor.

Ride Experience: Comfort Over Cornering

Suspension & Handling:
- Front: The 41 mm telescopic forks offer 110 mm (4.3 inches) of travel, soaking up potholes with ease.
- Rear: Dual shock absorbers provide 65 mm (2.6 inches) of travel, tuned for plushness rather than sportiness.

Brakes: Single discs front and rear, backed by ABS. The system isn’t as sharp as higher-end bikes but prevents wheel lockup reliably.

Tires: The 110/90-19 front and 130/80-18 rear tires prioritize stability over agility. Lean angles are limited, and the bike feels hesitant in tight corners. This isn’t a canyon carver—it’s a boulevard cruiser.

Wind Protection: Minimal. At highway speeds, the rider bears the brunt of windblast. Consider adding an aftermarket windscreen for longer rides.

Competition: How Does It Stack Up?

The retro 400cc segment is fiercely competitive. Here’s how the Imperiale 400 compares:

1. Royal Enfield Classic 350:
2. Pros: More authentic heritage, lighter at 195 kg (430 lbs), lower price.

3. Cons: Less power (20.2 HP), no fuel injection in older models, weaker brakes.

4. Honda CB350 (H’ness):

5. Pros: Honda reliability, smoother engine, Bluetooth-enabled instrumentation.

6. Cons: Less retro styling, higher seat height (800 mm / 31.5 inches).

7. Kawasaki W800:

8. Pros: Parallel-twin engine, premium build quality, superior highway performance.
9. Cons: Nearly double the price, heavier at 216 kg (476 lbs).

Verdict: The Benelli Imperiale 400 splits the difference between affordability and charm. It lacks the polish of the W800 or the brand cachet of Royal Enfield but offers a unique blend of retro styling and modern tech (like its TFT dash) at a accessible price point.

Maintenance: Keeping the Imperiale in Prime Shape

Owning a Benelli Imperiale 400 isn’t labor-intensive, but attention to detail pays off:

1. Oil Changes: Use SAE 10W-50 or 15W-50 oil. Capacity is 2.5 liters (0.66 gallons) with a filter change. MOTOPARTS.store recommends Motul 7100 10W-50 for optimal engine protection.

2. Valve Adjustments: Check every 6,000 km (3,728 miles).

3. Intake valves: 0.08–0.12 mm (0.003–0.005 in).

4. Exhaust valves: 0.10–0.14 mm (0.004–0.006 in).

5. Chain Care: The O-ring chain needs cleaning and lubrication every 500 km (310 miles). Try MOTOPARTS’s Heavy-Duty Chain Lube for longevity.

6. Tire Pressure:

7. Front: 2.2 bar (32 psi).

8. Rear: 2.5 bar (36 psi).

9. Brake Fluid: Flush with DOT 4 fluid annually.

Common Issues:
- Rust on Spokes: Apply anti-corrosion spray regularly.
