Aprilia SR 125 (2012-2017) Review: The Sporty Urban Companion

Introduction

The Aprilia SR 125, produced between 2012 and 2017, remains a standout in the 125cc scooter segment. Designed to inject sporty DNA into daily commutes, this Italian machine blends practicality with a dash of Supermotard-inspired flair. Whether navigating tight city streets or carving through suburban roads, the SR 125 positions itself as a spirited alternative to bland urban scooters. Let’s dissect its strengths, quirks, and legacy.

Design & Ergonomics: Urban Aggression Meets Functionality

The SR 125’s design borrows cues from Aprilia’s racing heritage, particularly the RSV4 superbike. The angular bodywork, pronounced front “beak” (a nod to off-road bikes), and blacked-out 14-inch wheels give it a rugged, adventurous aesthetic. The compact dimensions (1,953 mm long, 720 mm wide) and low 775 mm (30.5") seat height make it accessible for riders of all statures, while the flat footrests offer a relaxed riding posture.

Practical touches include a 7-liter fuel tank (1.85 US gal) and a spacious under-seat compartment large enough to fit a flip-up helmet. Color options like matte orange, black/red, and white/red add youthful vibrancy. However, the minimalist bodywork leaves little room for wind protection—a trade-off for its sporty silhouette.

Performance: Small Engine, Big Personality

Engine & Transmission

At its heart lies a 124cc, air-cooled, single-cylinder 4-stroke engine with a SOHC 2-valve setup. Producing 9.3 HP (6.8 kW) at 8,500 RPM and 8.1 Nm (6.0 lb-ft) of torque at 7,500 RPM, it’s tuned for low-to-mid-range responsiveness. The automatic CVT transmission eliminates gear-shifting hassles, making it ideal for stop-and-go traffic.

While top speed is limited to ~90 km/h (56 mph), the SR 125 shines in urban acceleration. The throttle response is crisp, and the “torque server” system smoothens power delivery, reducing jerky transitions common in budget CVTs.

Ride Experience

Twist the throttle, and the SR 125 leaps forward with surprising eagerness. The lightweight 122 kg (269 lbs) chassis amplifies the sensation of speed, while the 14-inch wheels provide stability over potholes. On open roads, the lack of wind protection becomes apparent, but the engine remains composed at 70-80 km/h (43-50 mph).

Handling & Braking: Agile, But With Compromises

Suspension & Frame

The steel cradle frame pairs with basic suspension: a non-adjustable 32 mm telescopic fork up front and a rear mono-shock with 82 mm (3.2") of travel. Setup is firm, favoring agility over plushness. Sharp turns are a joy—the SR 125 leans eagerly, and the wide handlebars offer precise control. However, rough roads expose its stiff ride; upgrading to aftermarket shocks (available at MOTOPARTS.store) can mitigate this.

Braking System

A 220 mm front disc with a dual-piston caliper and a 140 mm rear drum provide adequate stopping power. The front brake bites confidently, but the rear drum lacks progression. Swapping to sintered brake pads or a larger rear disc (compatible parts available in our catalog) enhances safety for aggressive riders.

Competition: How It Stacks Up

1. Yamaha NMAX 125

The NMAX counters with a liquid-cooled engine, more storage, and a plush ride. However, its softer styling and heavier 127 kg (280 lbs) weight lack the SR 125’s sporty edge.

2. Honda PCX 125

Honda’s offering prioritizes refinement, with a quieter engine and better wind protection. Yet, the PCX feels sterile compared to the Aprilia’s raucous character.

3. Vespa Primavera 125

Vespa’s retro charm and build quality command a premium. The Primavera is smoother but less engaging dynamically.

Verdict: The SR 125 targets riders seeking style and fun over outright practicality. It’s the scooter equivalent of a hot hatch—flawed but lovable.

Maintenance: Keeping the Aprilia SR 125 Thriving

Key Considerations:

1. Oil & Fluids:
2. Use SAE 5W-40 API SL oil (0.9L without filter).
3. Brake fluid: DOT 4.

4. Final drive oil: 80W-90 GL-4 (80 ml).

5. Valve Adjustments:

6. Intake: 0.10 mm (0.004") / Exhaust: 0.15 mm (0.006") when cold.

7. Tire Pressure:

8. Front: 2.0 bar (29 psi) / Rear: 2.2 bar (32 psi).

9. Spark Plug:

10. NGK CR7EB with a 0.7–0.8 mm electrode gap.

Common Upgrades:

• Suspension: Fit adjustable rear shocks for improved comfort.
• Exhaust: A slip-on aftermarket pipe (Euro 3-compliant) adds a throatier note.
• Brakes: Upgrade to braided steel lines for firmer lever feel.

Conclusion: A Scooter With Soul

The Aprilia SR 125 isn’t perfect—it’s cramped for tall riders, thirsty for a 125cc (22–25 km/L or 52–59 mpg), and lacks weather protection. Yet, its flaws are overshadowed by sheer charisma. Few scooters in this class deliver such a visceral connection to the road.

For owners, MOTOPARTS.store offers a range of upgrades to sharpen its performance or add practicality. From sportier tires to premium lubricants, we’ve got your SR 125 covered.

Agile, audacious, and unapologetically Italian—the SR 125 proves commuting needn’t be mundane.
