Introduction

The Aprilia SR 50 AC isn’t just another 50cc scooter—it’s a statement.

Design & Aesthetics: Supermoto Attitude Meets Scooter Practicality

The SR 50 AC’s design screams “supermoto,” borrowing cues from Aprilia’s off-road heritage. The angular bodywork, aggressive headlight cluster, and exposed chassis give it a rugged, athletic profile. Color options like Matt Black, White Lucido, and Grey/Red amplify its sporty vibe, while the textured seat with red stitching adds a premium touch.

At 1,953 mm (76.9 inches) long and 720 mm (28.3 inches) wide, it’s compact enough for lane-splitting yet substantial enough to feel stable. The 14-inch gloss-black wheels—unusually large for a scooter—are a standout feature, wrapped in chunky 120/70 tires that hint at its dual-sport inspiration. Under the seat, a 7-liter (1.85-gallon) storage compartment fits a flip-up helmet, a rarity in this class.

The cockpit is minimalist but functional. Analog gauges display speed and fuel, while the flat handlebars and upright riding position channel supermoto ergonomics. It’s a scooter that doesn’t just blend into traffic—it demands attention.

Performance: Small Engine, Big Personality

Engine & Transmission

Powered by a 49.9cc air-cooled, four-stroke engine, the SR 50 AC delivers 4.6 HP at 9,500 RPM and 3.8 Nm (2.8 ft.lbs) of torque. While these numbers won’t set speed records, the engine’s character is perfect for city riding. The Keihin NCV F20 carburetor provides crisp throttle response, and the automatic belt-driven transmission eliminates gear-shifting hassles.

Acceleration is leisurely—0–40 km/h (0–25 mph) takes its time—but the engine thrives in stop-and-go traffic. Top speed hovers around 50–55 km/h (31–34 mph), ideal for urban zones. The four-stroke design ensures reliability and fuel efficiency, with Aprilia claiming up to 40 km/l (94 mpg).

Handling & Suspension

The SR 50 AC’s chassis is its secret weapon. The aluminum perimeter frame and 14-inch wheels provide surprising stability, while the hydraulic telescopic fork (86 mm travel) and rear monoshock (76 mm travel) soak up potholes better than most scooters.

At 106 kg (233 lbs), it’s light enough to flick through traffic but planted enough to feel secure. The wide tires grip well on wet roads, and the 220 mm front disc brake (with a two-piston caliper) offers confident stopping power. The rear drum brake, while less potent, is adequate for its speed range.

Riding Experience: Urban Agility with a Sporty Edge

Ergonomics & Comfort

With a seat height of 775–820 mm (30.5–32.3 inches), the SR 50 AC suits shorter riders but remains accessible. The seat is firm yet supportive for short commutes, though hour-long rides might test your patience. The floorboard is spacious, and the upright riding position ensures good visibility in traffic.

City Performance

This scooter shines in urban environments. The narrow profile lets you squeeze through tight spaces, and the peppy low-end torque makes accelerating from lights a breeze. The belt drive is virtually maintenance-free, and the Euro 2-compliant engine keeps emissions in check.

Quirks & Drawbacks

• Vibrations: The single-cylinder engine sends noticeable buzz to the handlebars at higher RPMs.
• Storage Limitations: While the under-seat compartment is generous, there’s no front storage.
• Wind Protection: Minimal. Speeds above 45 km/h (28 mph) leave you wishing for a small windscreen.

Competition: How Does the SR 50 AC Stack Up?

1. Honda Vision 50

• Pros: Legendary reliability, smoother CVT, lower seat height.
• Cons: Bland styling, smaller 12-inch wheels.
• Verdict: The Vision is a practical workhorse, but the Aprilia wins on style and handling.

2. Yamaha Aerox 50

• Pros: Faster liquid-cooled engine, sportier acceleration.
• Cons: Higher maintenance costs, louder exhaust.
• Verdict: The Aerox is quicker, but the SR 50 AC’s four-stroke engine is more frugal.

3. Peugeot Speedfight 4

• Pros: Lightweight, sharp handling, vibrant colors.
• Cons: Cramped seat, dated design.
• Verdict: The Speedfight is fun, but the Aprilia’s supermoto flair gives it broader appeal.

Maintenance: Keeping Your SR 50 AC in Top Shape

Key Considerations

1. Belt Drive: Inspect the drive belt every 5,000 km (3,100 miles) for wear. Upgrade to a high-performance kit for smoother acceleration.
2. Carburetor Tuning: Clean the Keihin carburetor annually to prevent clogs. Consider a jet kit for improved throttle response.
3. Brake Fluid: Flush the DOT 4 fluid every two years. Swap the rear drum pads for sintered variants if you ride aggressively.
4. Tires: The 120/70-14 tires strike a balance between grip and longevity. For wet weather, try Pirelli Angel Scooter rubber.
5. Spark Plugs: The NGK BR8ES is standard, but the iridium BR8EIX offers better longevity.

Recommended Upgrades from MOTOPARTS.store
