Aprilia SR 125 (1999-2002) Review: A Nostalgic Romp Through the Golden Era of 2-Stroke Scooters

Introduction

The Aprilia SR 125 represents a thrilling snapshot of European scooter culture at the turn of the millennium. As part of Aprilia's "Sport Rapid" lineage, this 2-stroke warrior carved its niche among riders who craved urban agility with a dash of sporty flair. Produced from 1999 to 2002, it remains a cult favorite today - not just for its retro charm, but for the raw, unfiltered riding experience that modern 4-strokes struggle to replicate. Let’s twist the throttle and see what makes this Italian stallion tick.

Design: Aggressive Lines Meet Functional Simplicity

The SR 125’s design screams "sport" from every angle. The sharp, angular bodywork was revolutionary for scooters in its era, ditching the curvaceous norms for a look that could’ve been teleported from Aprilia’s RS 125 sportbike catalog. The twin-headlamp setup (a signature SR motif) and raked front end give it purposeful road presence, while the stepped saddle (815 mm/32" seat height) strikes a balance between sporty crouch and commuter comfort.

Build quality feels typically Mediterranean - plastics aren’t Lexus-level, but the tubular steel frame has proven resilient against time. The analog dashboard is refreshingly simple: just a speedometer, fuel gauge, and basic warning lights. Storage is minimal (the underseat compartment barely fits a half-helmet), reminding us this was designed for speed, not grocery runs.

Performance: The Sweet Scream of Two-Stroke Fury

At its heart lies a 123cc single-cylinder 2-stroke engine pumping out 13 PS (9.8 kW). Numbers don’t tell the full story - this is an engine that lives in the upper rev range. Below 5,000 RPM? Sluggish and smoky. Past 6,500 RPM? Suddenly you’re riding a chainsaw-powered rocket. The powerband hits like an espresso shot, propelling the 112 kg (247 lbs) scooter to a 95 km/h (59 mph) top speed that feels twice as fast thanks to the open-air experience.

The automatic CVT transmission eliminates gear shifts, making it ideal for stoplight dashes. Fuel consumption averages 30 km/L (70 mpg) if you resist the urge to pin the throttle constantly. Just remember - this being a 2-stroke, you’ll either be premixing fuel or relying on the oil injection system (check those hoses!). The exhaust note is a metallic rasp that attracts attention - part race bike, part angry hornet swarm.

Handling: Carving Corners Like a Pizza Knife

Where the SR 125 truly shines is in the twisties. The short 1,330 mm wheelbase and low center of gravity make it flickable enough to embarrass larger motorcycles. The telescopic front forks (110 mL SAE 10W oil) and dual rear shocks handle urban potholes with Italian flair - compliant yet communicative.

Tire pressures matter here: 1.9 bar (28 psi) front and 2.1 bar (30 psi) rear when riding solo. Sticky rubber and the lightweight chassis allow knee-down cornering antics that feel illicit on a scooter. Braking is via a single 220 mm front disc and 140 mm rear drum - adequate for the weight, though modern sintered pads from MOTOPARTS.store would sharpen response.

Competition: How the SR 125 Stacks Up

Honda SH125

The Honda’s 4-stroke engine is smoother and thriftier (40 km/L), but its 9.5 PS output feels anemic compared to the Aprilia’s explosive power delivery. The SH125 prioritizes practicality with better storage, but can’t match the SR’s cornering joy.

Yamaha Aerox 125

Yamaha’s answer had water-cooling and slightly more power (14.5 PS), but weighed 128 kg (282 lbs). The Aerox felt more planted at speed but lost the Aprilia’s flickable nature. Maintenance was also more complex with its liquid-cooled system.

Peugeot Speedfight 125

This French rival matched the SR’s aggression in styling and performance. However, build quality and reliability were often questioned. The Aprilia’s simpler air-cooled design aged better mechanically.

Verdict: The SR 125 wasn’t the most practical or refined, but it dominated in character and sporty thrills.

Maintenance: Keeping the 2-Stroke Spirit Alive

Owning a 20+ year-old 2-stroke requires some mechanical sympathy. Here’s your MOTOPARTS.store checklist:

1. Engine Oil

2. Use quality 2-stroke oil at a 50:1 mix ratio (1.6 oz oil per 1 gallon fuel). Synthetic options reduce spark plug fouling.

3. Spark Plugs

4. Original spec NGK BR8ES works, but upgrade to the iridium BR8EIX (0.6 mm gap) for better cold starts and longevity.

5. Final Drive

6. Despite being chain-free (direct drive via CVT), inspect the drive belt every 5,000 km. Replace if cracked or worn below 21 mm width.

7. Cooling System

8. Fan-cooled design stays simple. Clean debris from the cooling fins regularly. Overheating? Check for carbon buildup in the exhaust powervalve.

9. Brake Fluid

10. Flush DOT 4 fluid every 2 years. Sticky levers? A MOTOPARTS.store stainless steel brake line kit improves feel.

11. Tires

12. Modern radial tires (like Michelin City Grip) transform wet grip compared to vintage rubber.

Pro Tip: Decarbonize the exhaust chamber annually - 2-strokes love to gum up with carbon deposits.
