Aprilia Tuono 660 (2021-2022): The Lightweight Sport Naked That Redefines Accessibility

Introduction

The Aprilia Tuono 660 isn’t just a motorcycle—it’s a statement. Born from the DNA of its legendary V4 sibling, this middleweight sport naked bridges the gap between track-focused aggression and everyday usability. With a 659cc parallel twin engine, a featherweight chassis, and electronics borrowed from Aprilia’s MotoGP-bred RSV4, the Tuono 660 challenges the notion that "accessible" means "compromised." For riders seeking adrenaline without intimidation, this bike is a revelation.

Let’s dissect what makes the Tuono 660 a standout in its class, from its razor-sharp handling to its uncanny ability to morph from commuter to canyon carver with a twist of the throttle.

Design & Aesthetics: Aggression Meets Aerodynamics

The Tuono 660’s design is a masterclass in functional minimalism. Its sharp lines and compact proportions scream sportbike pedigree, while the signature triple-LED headlight cluster—flanked by perimeter DRLs—gives it a futuristic edge. The Factory variant amps up the drama with "Dark Factory" graphics and a single-seat tail fairing, but even the base model oozes sophistication.

Aprilia’s double-layer fairing isn’t just for show. Channeling airflow between its panels reduces drag and stabilizes the bike at speed, while shielding the rider from buffeting. At 1995 mm (78.5 in) long and with a 1370 mm (53.9 in) wheelbase, it’s compact enough to flick through traffic yet planted enough to inspire confidence mid-corner.

Color options like Acid Gold and Iridium Gray ensure you’ll stand out in a sea of monotone nakeds. The Factory model’s blacked-out accents and red highlights, however, are for those who prefer their style with a side of menace.

Engine & Performance: A Twin With a Soul

At the heart of the Tuono 660 lies a 659cc parallel twin derived from Aprilia’s RSV4 engine. But this isn’t just a detuned powerhouse—it’s a reimagined marvel. The 270° crankshaft mimics the pulse of a V-twin, delivering a throaty exhaust note and linear power delivery.

• Power: 95 HP (70 kW) @ 10,500 rpm (100 HP for the Factory variant)
• Torque: 67 Nm (49.4 lb-ft) @ 8,500 rpm
• Weight: 183 kg (403.4 lbs) wet / 181 kg (399 lbs) for Factory

The numbers tell only half the story. From 4,000 rpm, 80% of torque is already on tap, making city riding a breeze. Snap the throttle open, and the engine builds momentum like a crescendo—smooth but urgent, with a ferocious top-end rush that belies its middleweight status.

The Factory model’s shorter final drive (16/43 sprockets vs. 17/43) sharpens acceleration, while the lithium battery shaves 2 kg (4.4 lbs). Paired with the optional Akrapovič exhaust (for track use), the engine transforms into a snarling beast—though even the stock setup delivers a soundtrack worthy of head-turns.

Handling & Chassis: Precision Personified

Aprilia’s aluminum twin-spar frame is a work of art. Lightweight yet rigid, it’s mated to an asymmetric swingarm that bolts directly to the engine—a trick borrowed from the RSV4. The result? A chassis that’s agile enough for tight corners yet stable at triple-digit speeds.

• Front Suspension: 41 mm KYB USD fork (rebound/preload adjustable)
• Rear Suspension: Sachs monoshock (rebound/preload adjustable)
• Brakes: Dual 320 mm Brembo discs (front) / 220 mm single disc (rear)

The Factory variant upgrades to fully adjustable suspension, but even the base setup strikes a near-perfect balance between sport and street. At 24.1° of rake and 104.7 mm (4.1 in) of trail, the Tuono turns in with telepathic precision. The wide handlebars offer leverage for quick direction changes, while the 820 mm (32.3 in) seat height accommodates most riders without sacrificing ground clearance.

Push hard into a corner, and the Bridgestone Battlax Hypersport S22 tires (120/70-17 front, 180/55-17 rear) grip like glue. The Brembos deliver bite without being overly aggressive—perfect for trail-braking enthusiasts.

Electronics & Rider Aids: A Tech Playground

The Tuono 660’s APRC (Aprilia Performance Ride Control) suite rivals systems found on liter-class superbikes:

1. ATC (Traction Control): Six levels of intervention, from rainy-day caution to track-day leniency.
2. AWC (Wheelie Control): Keep the front wheel grounded—or let it hover, your choice.
3. AQS (Quick Shifter): Butter-smooth up/down shifts without clutch input.
4. AEB (Engine Brake): Adjust how aggressively the engine slows you on throttle closure.
5. Cornering ABS: Brake mid-lean without fear of washing out.

Five riding modes (three road, two track) let you tailor the experience. "Commute" mode softens throttle response and maxes out traction control, while "Track" unleashes the engine’s full fury and dials back electronic nannies. The 5-inch TFT dash is intuitive, with Bluetooth connectivity for smartphone integration.

Competition: How Does It Stack Up?

The Tuono 660 faces fierce rivals, but it carves its niche with a blend of tech and character:

1. Yamaha MT-07:
2. Cheaper but barebones. Missing cruise control, adjustable suspension, and cornering ABS.

3. Crossplane twin is torquey but lacks the Aprilia’s top-end scream.

4. Triumph Street Triple RS:

5. Sharper suspension (Showa/Brembo) and a 118 HP triple-cylinder engine.

6. Pricier and heavier (188 kg / 414 lbs). The Tuono counters with better electronics.

7. Kawasaki Z900:

8. 948cc inline-four offers brute force (92.2 HP) but feels bulkier.

9. Lacks the Aprilia’s finesse in corners and tech package.

10. Ducati Monster (937):

11. Iconic design and a 111 HP V-twin.
12. Higher seat (840 mm), twitchier throttle, and a heftier price tag.

Verdict: The Tuono 660 isn’t the most powerful, but its combination of lightweight agility, advanced electronics, and V4-derived DNA makes it the most engaging option for riders who value precision over brute force.

Maintenance: Keeping the Beast Happy

The Tuono 660 is relatively low-maintenance for a performance machine, but attention to detail pays dividends:

• Oil Changes: Use SAE 10W-50 API SL oil every 9,000 km (5,600 mi) or annually. Capacity: 2.3L (2.4 qts) with filter.
• Valve Clearances: Check every 24,000 km (15,000 mi). Intake: 0.10–0.15 mm (0.004–0.006 in), exhaust: 0.10–0.20 mm (0.004–0.008 in).
• Tire Pressures: 2.5 bar (36 psi) front / 2.8 bar (41 psi) rear (cold).
• Chain Care: 110-link chain requires regular lubrication. Factory sprockets (16/43) wear faster—upgrade to premium aftermarket kits for longevity.
• Cooling System: 1.8L (1.9 qts) of coolant, replaced every 2 years.

Pro Tip: The slipper clutch reduces rear-wheel hop during aggressive downshifts, but pairing it with the AQS system requires smooth inputs. Consider upgrading to a sintered brake pad compound for track days.
