Gilera Runner 125 2T (2002–2021) Review: The Two-Stroke Urban Legend That Refuses to Quit
Introduction
For nearly two decades, the Gilera Runner 125 2T carved its name into the streets of Europe and beyond as a feisty, unapologetically raw scooter that blended practicality with a shot of adrenaline. Produced from 2002 to 2021, this two-stroke warrior became a cult classic among urban riders and tuning enthusiasts. Unlike its four-stroke competitors, the Runner 125 2T thrived on simplicity, lightweight agility, and that unmistakable two-stroke scream. But does it still hold up as a daily rider or a weekend thrill machine? Let’s twist the throttle and find out.
Design & Styling: Aggressive Lines Meet Functional Practicality
The Gilera Runner 125 2T’s design screams “sport scooter” from every angle. With sharp, angular bodywork, a low-slung front fairing, and a stepped seat that hints at its racing pedigree, it looks like it’s doing 100 km/h even when parked. The compact dimensions (typical of 125cc scooters) make it ideal for slicing through traffic, while the bold color schemes—often in metallic reds, blacks, or whites—give it a youthful flair.
Practicality isn’t sacrificed for style. The under-seat storage fits a full-face helmet (barely), and the flat floorboard offers space for small bags. The analog-digital dashboard is basic but legible, with a prominent tachometer—a rare feature in scooters that underscores its performance focus. Build quality is typical of early-2000s Gilera: functional but not luxurious. Plastic panels can feel flimsy, but they’re easy to replace (hint: MOTOPARTS.store stocks OEM-style replacements).
Engine & Performance: Two-Stroke Fury in a 125cc Package
Specs at a Glance
- Engine: 123cc single-cylinder two-stroke
- Power: 15 PS (11 kW) @ ~8,000 RPM
- Top Speed: 95 km/h (59 mph)
- Fuel Capacity: 8.5 liters (2.24 gallons)
The heart of the Runner 125 2T is its air-cooled two-stroke engine—a rarity in modern scooters. Fire it up, and the exhaust note immediately sets it apart: a raspy, high-pitched growl that’s music to any gearhead’s ears. Throttle response is razor-sharp, delivering a surge of power from idle to its 9,500 RPM redline. Acceleration from 0–60 km/h (0–37 mph) feels brisk, outpacing many four-stroke rivals like the Honda SH125.
But two-strokes have quirks. The engine thrives on revs, so keeping it in the “power band” requires aggressive riding. Fuel economy suffers compared to four-strokes—expect ~30 km/l (70 mpg) versus 40+ km/l (94+ mpg) for competitors. You’ll also need to mix oil with fuel (unless your model has an oil-injector), which adds a layer of old-school charm (or hassle, depending on your patience).
Handling & Ride Experience: Urban Ninja, Weekend Corner Carver
Weighing in at ~115 kg (253 lbs), the Runner 125 2T feels flickable and light on its feet. The short wheelbase and wide handlebars make weaving through traffic effortless, while the stiff suspension setup (35mm front forks, dual rear shocks) keeps things stable at speed. Push it into a corner, and the 12-inch wheels grip predictably, though the stock tires (90/90 front, 120/80 rear) lack the bite for aggressive riding.
Ride quality is firm—perfect for smooth asphalt but jarring over potholes. The seat is thinly padded, making long rides a test of endurance. Still, the riding position is upright and comfortable for riders under 180 cm (5’11”). For city commutes or short blasts on twisty roads, it’s a riot.
Braking & Safety: Adequate, But Begs for Upgrades
The Runner 125 2T came with a front hydraulic disc brake and a rear drum—a common setup for its class. The front brake offers decent bite, but the rear drum feels vague. In wet conditions, the lack of ABS becomes apparent, requiring careful modulation.
Pro Tip: Upgrade to sintered brake pads (available at MOTOPARTS.store) for improved stopping power. Swapping to a braided steel brake line further sharpens response.
Competition: How the Runner Stacks Up Against the Rivals
1. Yamaha Aerox 125 (4-Stroke)
- Pros: Better fuel economy, modern styling, liquid-cooled engine.
- Cons: Heavier (123 kg), less peak power (12 PS).
- Verdict: The Aerox is the sensible choice, but it lacks the Runner’s raw character.
2. Aprilia SR 125
- Pros: Sporty design, similar agility, four-stroke reliability.
- Cons: Softer power delivery, higher maintenance costs.
- Verdict: A stylish alternative but doesn’t deliver the same adrenaline rush.
3. Honda SH Mode 125
- Pros: Legendary reliability, cavernous storage, smooth ride.
- Cons: Boring to ride, looks like a “grandma scooter.”
- Verdict: Perfect for practicality, but you’ll yawn through every commute.
The Runner’s Edge: It’s the only two-stroke in this lineup, offering a visceral riding experience that’s hard to replicate. Tuning potential is massive—bolt-on big-bore kits can push power past 20 PS!
Maintenance: Keeping the Two-Stroke Alive
Owning a Runner 125 2T is a labor of love. Two-strokes demand more attention than their four-stroke cousins, but the payoff is worth it.
Key Maintenance Tips:
- Spark Plugs: The NGK B9ES (gap: 0.8mm) is critical for smooth ignition. Replace every 5,000 km (3,100 miles).
- Premix/Oil Injection: Use high-quality two-stroke oil (1.5–2% ratio if premixing). Clogged oil lines? MOTOPARTS.store sells OEM replacements.
- Cooling System: The 1.74L coolant capacity needs annual flushing. Use ethylene glycol-based coolant to prevent corrosion.
- Exhaust Cleaning: Two-strokes gum up exhausts with carbon. Decoke it every 10,000 km (6,200 miles).
- Gear Oil: Replace the 80ml SAE 80W-90 endantriebsöl every 8,000 km (5,000 miles).
Common Issues:
- Cold Starts: Choke required in cool weather.
- Vibrations: Engine mounts wear out—check rubber dampers.
- Carburetor Jetting: Stock settings run lean; richer jetting improves reliability.
MOTOPARTS.store Recommendations:
- Upgrade to a performance exhaust (Malossi or LeoVince) for extra power.
- Install a reinforced drive belt for smoother acceleration.
- Swap to Michelin City Grip tires for better wet-weather traction.
Conclusion: A Thrilling Anachronism
The Gilera Runner 125 2T isn’t just a scooter—it’s a statement. It’s for riders who crave the mechanical connection of a two-stroke, who don’t mind getting their hands dirty, and who value fun over frugality. While newer scooters prioritize emissions compliance and fuel efficiency, the Runner remains a rebellious throwback to a simpler, louder era.
Is it practical? Not really. Is it unforgettable? Absolutely. And with MOTOPARTS.store’s extensive catalog of upgrades and replacement parts, keeping this legend alive has never been easier. Ride hard, rev higher, and let the two-stroke symphony play on.
