Benelli TNT 899 (2008–2017): A Roaring Italian Middleweight with Soul

Introduction

The Benelli TNT 899 is a motorcycle that refuses to blend into the background. Produced from 2008 to 2017, this Italian naked bike carved its niche with a combination of brash styling, a charismatic inline-three engine, and a chassis that balances aggression with accessibility. Unlike its Japanese counterparts, the TNT 899 doesn’t prioritize clinical precision—it’s a machine that thrives on emotion, offering a raw, unfiltered riding experience.

Whether you’re drawn to its underseat exhaust, trellis frame, or the growl of its 899cc triple, the TNT 899 demands attention. Let’s dissect what makes this motorcycle a compelling choice for riders seeking character in a segment often dominated by conformity.

Design: Aggression Meets Italian Flair

The TNT 899’s design is unapologetically bold. From its insectoid headlight cluster to the muscular fuel tank and minimalist tail section, every angle screams Italian audacity. The steel trellis frame, paired with cast aluminum alloy sections, isn’t just structural—it’s a visual centerpiece, showcasing Benelli’s engineering flair.

Key Design Features:

• Underseat Exhaust: A signature element that elevates the bike’s aesthetics (and your posterior’s temperature in traffic).
• Color Options: Variants like the Café Racer and Century Racer added black/yellow or orange schemes, while base models offered white/red or black.
• Ergonomics: With a seat height ranging from 780–830 mm (30.7–32.7 in), it accommodates shorter riders without sacrificing sporty intent. The wide handlebars encourage an upright posture, ideal for urban agility.

The exposed engine and chunky swingarm reinforce its mechanical authenticity. Practicality isn’t forgotten—the 16–17L fuel tank (4.2–4.5 US gal) offers decent range, though wind protection is nonexistent (as expected in a naked bike).

Engine and Performance: The Heart of the Beast

At the core of the TNT 899 lies its 898cc inline-three engine, a configuration that splits the difference between the twin’s low-end grunt and the four-cylinder’s top-end scream.

Power Delivery:

• Peak Output: 118–120 HP (87–88 kW) @ 9,500 RPM
• Torque: 88 Nm (64.9 lb-ft) @ 8,000 RPM
• Throttle Response: Fuel injection (53mm throttle bodies) provides crisp response, though early models had occasional low-RPM hesitancy.

The engine’s personality shines in the midrange. From 5,000 RPM onward, the triple surges forward with a linear, addictive pull, accompanied by a throaty exhaust note that’s more industrial symphony than polite purr. The 6-speed gearbox slots cleanly, though the clutch can feel heavy in stop-and-go traffic.

Performance Metrics:

• Top Speed: 235 km/h (146 mph)
• Fuel Economy: ~5.3 L/100 km (43.3 US mpg)

This isn’t a hyper-naked—it’s a bike that rewards spirited canyon carving more than outright track dominance.

Handling and Ride Experience: Controlled Chaos

Benelli paired the TNT 899’s engine with a chassis that’s equal parts agile and stable. The 1,443 mm (56.8 in) wheelbase strikes a balance between flickability and straight-line composure.

Suspension and Brakes:

• Front: Marzocchi 43–50mm USD forks (adjustable on higher trims)
• Rear: Sachs monoshock with preload/rebound adjustment
• Brakes: Dual 320mm front discs with 4-piston calipers; single 240mm rear disc

The setup leans toward sporty stiffness, transmitting road texture without beating you up. Push hard into corners, and the TNT 899 responds with neutral steering, though the 190-section rear tire (vs. the Triumph Street Triple’s 180) adds stability at the expense of quick direction changes.

Weight Considerations:

At 208–215 kg (459–474 lbs) wet, it’s no featherweight, but the mass centralization keeps it manageable. The Café Racer and Century Racer trims shaved weight with alloy subframes and wave brake discs.

Competition: How Does It Stack Up?

The TNT 899’s closest rivals are European, but it’s priced closer to Japanese offerings. Let’s break it down:

1. Triumph Street Triple 675

• Pros: Lighter (183 kg / 403 lbs), sharper handling, iconic design.
• Cons: Smaller engine, less midrange torque.
• Verdict: The Triumph is the better all-rounder, but the Benelli counters with larger displacement and Italian flair.

2. Ducati Monster 796

• Pros: Desmo V-twin character, brand prestige.
• Cons: Less power (87 HP), air-cooled limitations.
• Verdict: The Monster excels in urban settings; the TNT 899 dominates open roads.

3. Yamaha MT-09

• Pros: Modern electronics, lower cost of ownership.
• Cons: Bland aesthetics, less tactile feedback.
• Verdict: The MT-09 is pragmatic; the Benelli is for enthusiasts.

The TNT 899 isn’t the most refined or reliable in its class—but it’s arguably the most soulful.

Maintenance: Keeping the Italian Fire Alive

Owning a TNT 899 requires mechanical sympathy. Here’s what to prioritize:

Key Maintenance Tips:

1. Valve Adjustments: Every 12,000 km (7,500 mi). The DOHC engine demands precise shim adjustments.
2. Cooling System: Flush coolant every 2 years. Early models had occasional thermostat issues.
3. Chain Care: The final drive chain needs frequent lubrication (every 500 km / 300 mi) to mitigate wear.
4. Brake Upgrades: Swap stock pads for sintered variants (e.g., EBC HH) for improved bite.
5. Suspension Tuning: Stiffer fork springs (optional on base models) enhance cornering stability.

Common Upgrades:

• Exhaust: Aftermarket slip-ons (like Arrow or SC Project) reduce weight and amplify the triple’s growl.
• ECU Tuning: Address flat spots in low-RPM fueling.
• Ergonomics: Gel seats or bar risers improve comfort for long rides.
