Peugeot 50 Ludix Blaster RS12 (2004-2018): A Generational Icon Revisited

Introduction

The Peugeot 50 Ludix Blaster RS12 isn’t just a scooter—it’s a cultural artifact. For 14 years, this nimble two-stroke dominated European streets, offering a blend of practicality, simplicity, and just enough cheeky character to appeal to both teenagers and urban commuters. Whether you’re threading through Parisian traffic or bombing down a country lane, the Ludix Blaster RS12 feels like a trusty sidekick that’s always ready for adventure. Having spent a week with a well-preserved 2012 model, I’m here to break down why this Peugeot remains relevant—and why it’s still a canvas for customization.

Design & Ergonomics

Compact Dimensions, Maximum Utility

At 1,725 mm (67.9 inches) long and 665 mm (26.2 inches) wide, the Ludix Blaster RS12 slips through gaps that would give most scooters claustrophobia. The design is unapologetically functional: flat floorboards, a narrow waist, and a high-mounted exhaust that screams “I mean business.” The RS12 variant adds sporty flourishes—a sharper front apron, dual-tone colors (black/white or silver/blue), and a raked windshield that looks lifted from a bigger maxi-scooter.

Seat Height:
- Base models like the Ludix One: 760 mm (29.9 inches)
- RS12/Blaster variants: 805 mm (31.7 inches)

The taller seat on the RS12 trades a smidge of low-speed stability for a commanding riding position. At 5’7”, I could flat-foot easily, but shorter riders might prefer the Ludix 2 One’s 760 mm (29.9-inch) perch.

Weight Matters:
- Lightest variant (Ludix 2 One): 66 kg (145.5 lbs)
- Blaster RS12: 79.5 kg (175.3 lbs)

That 13.5 kg (30 lb) difference is noticeable. The base Ludix feels like a bicycle with an engine, while the RS12’s liquid-cooled engine and sturdier frame add heft—but also stability at higher speeds.

Engine & Performance

The Two-Stroke Heartbeat

All Ludix Blaster models share a 49.9–50cc single-cylinder two-stroke engine, but cooling systems vary:
- Air-cooled: Found on budget models like the Ludix One. Simpler, lighter, but prone to heat soak in traffic.
- Liquid-cooled: RS12 and Blaster variants. Sustains power during extended runs—critical for riders tackling hills.

Power Output:
- 3.6–4.9 kW (4.4–6.2 HP), depending on tuning.
- Carbureted (Gurtner PY 12) with CDI ignition.

Twist the throttle, and the engine emits a raspy, enthusiastic buzz. Acceleration is brisk for a 50cc, hitting 45 km/h (28 mph) swiftly—enough to keep up with city traffic. The CVT transmission is seamless, though the belt drive (or shaft on some models) whines under hard acceleration.

Fuel Efficiency:
- 5.5–7.5 L (1.45–1.98 gal) tank
- Expect 35–45 km/l (82–106 mpg). A week of commuting cost less than a coffee.

Handling & Ride Quality

Urban Agility, Countryside Poise

The Ludix’s chassis is a masterclass in minimalist engineering. The steel frame, paired with a 1,210 mm (47.6-inch) wheelbase, strikes a balance between flickability and straight-line composure.

Suspension:
- Front: Reverse telescopic forks (73 mm / 2.9 inches of travel)
- Rear: Central hydraulic shock (65 mm / 2.6 inches)

Over cobblestones, the suspension clatters but never loses composure. The RS12’s wider tires (120/70-12 front, 130/70-12 rear) add grip, while base models skimp with 90/90-10s that feel twitchy on wet roads.

Braking:
- Front: 190 mm disc (RS12) or drum (budget models)
- Rear: 110 mm drum

The RS12’s front disc bites decisively, though ABS is absent. Drum-brake variants require planning—think “two Mississippi” before intersections.

Features & Variants

A Model for Every Rider

Peugeot released over a dozen Ludix/Blaster variants. Key differences:

| Model | Highlights | Weight | Tires |
|------------------|--------------------------------------------|---------------|--------------------|
| Ludix One | Kickstart, air-cooled, drum brakes | 66 kg (145.5 lbs) | 90/90-10 |
| Ludix 2 Elegance | Electric start, dual seat, rear carrier | 76 kg (167.6 lbs) | 100/80-10 |
| Blaster RS12 | Liquid-cooled, front disc, sport styling | 79.5 kg (175.3 lbs) | 120/70-12, 130/70-12 |
| Blaster RCup | Track-inspired graphics, tuned exhaust | 79.5 kg (175.3 lbs) | 130/90-10 |

The RS12 stands out with its inverted forks and aggressive stance, but even base models offer a color palette (black, red, white) to suit personal tastes.

Competition

How the Ludix Stacks Up

1. Yamaha Aerox 50
- Pros: Liquid-cooled, sportier design, 55 km/h top speed.
- Cons: Costlier maintenance, harsher ride.
Verdict: The Aerox is faster but less frugal.

2. Honda Vision 50
- Pros: Four-stroke reliability, 50+ km/l fuel economy.
- Cons: Duller throttle response, heavier.
Verdict: For commuters who prioritize longevity over fun.

3. Aprilia SR 50
- Pros: Premium suspension, 70 km/h (derestricted).
- Cons: Pricey parts, complex diagnostics.
Verdict: A weekend warrior’s toy—less practical daily.

Peugeot’s Edge: The Ludix Blaster RS12 splits the difference. It’s tunable, cheap to fix, and parts are everywhere.

Maintenance

Keeping the Legend Alive

1. Two-Stroke Care
- Oil Injection: The Dell’Orto pump mixes oil into the carburettor automatically. Use JASO-FD-certified 2T oil.
- Spark Plugs: NGK BR7HS (0.6–0.7 mm gap). Replace annually.

2. Carburetor TLC
The Gurtner PY 12 carb is reliable but clogs if neglected. Clean every 5,000 km (3,100 miles) or after winter storage.

3. Belt & Drivetrain
- CVT belts last ~12,000 km (7,500 miles). Swap earlier if you ride hard.
- Shaft-drive models need 120 ml of gear oil changes every 10,000 km (6,200 miles).

4. Brake Upgrades
Drum brakes fade under stress. Consider MOTOPARTS.store’s sintered pads or a 190 mm disc conversion kit.

5. Suspension Tweaks
The basic shocks sag over time. Progressive springs or a YSS shock transform cornering.
