Gilera Runner 125 4T (2001–2017): A Scooter Built for Urban Thrills and Practicality

Introduction

The Gilera Runner 125 4T is a scooter that defies the stereotype of “just another commuter machine.” Produced from 2001 to 2017, this Italian-designed two-wheeler carved out a niche as a sporty, practical, and surprisingly engaging ride for urban warriors and weekend explorers. With its blend of liquid-cooled engineering, agile chassis, and unmistakable styling, the Runner 125 4T remains a compelling choice even in today’s crowded scooter market. After spending time with this machine, it’s clear why it developed a cult following across Europe and beyond.

Design: Aggressive Lines Meets Functional Ergonomics

The Gilera Runner 125 4T’s design screams athletic intent. Unlike the curvy, understated profiles of many 125cc rivals, the Runner adopts sharp angles, exposed bodywork, and a forward-leaning stance that hints at its sporty DNA. The dual headlights (on later ST models) and angular front fairing give it a motorcycle-like presence, while the stepped seat and raised handlebars strike a balance between aggressive posture and everyday comfort.

At 815 mm (32.1 inches), the seat height accommodates riders of most statures, though shorter riders might prefer the VX variant’s lower 780 mm (30.7-inch) perch. The underseat storage compartment fits a full-face helmet, and the 8.5–12-liter fuel tank (depending on submodel) ensures reasonable range for city rides or weekend getaways. Color options like Rosso Dragon (Dragon Red) and Nero Lucido (Gloss Black) add a touch of Mediterranean flair.

Engine and Performance: Small Displacement, Big Character

The heart of the Runner 125 4T is its liquid-cooled, 124cc single-cylinder engine—a rarity in the 125cc scooter class where air-cooling still dominates. With 14.5 HP (10.6 kW) peaking at 9,750 RPM and 11.7 Nm (8.6 lb-ft) of torque at 8,000 RPM, this isn’t a powerhouse, but it’s tuned for responsive urban riding. The carbureted variants (ST models) deliver a punchy low-to-midrange, while fuel-injected versions (VX/SC trims) offer smoother throttle response and better fuel efficiency.

Twist the throttle, and the CVT transmission sends power seamlessly to the rear wheel, hitting a top speed of 108 km/h (67 mph)—enough to hold its own on city ring roads. The liquid cooling system shines in stop-and-go traffic, preventing the dreaded power fade that plagues air-cooled competitors. Euro 3 compliance ensures cleaner emissions, though tuning enthusiasts might find the stock exhaust note overly polite.

Handling and Comfort: Carving Corners Like a Pro

Where the Runner 125 4T truly surprises is in its handling. The steel tube frame and 1,340 mm (52.8-inch) wheelbase provide a stable yet nimble base, while suspension setups vary by model: - ST models: 35 mm telescopic front forks + twin rear shocks (4-position preload adjustment) - VX/SC models: Similar front forks + adjustable dual rear dampers

Paired with 14-inch front wheels (ST) or 12-inch setups (VX), the Runner leans into corners with a confidence that belies its scooter roots. The 220 mm front and rear discs (single or dual-piston calipers) offer ample stopping power, though aftermarket brake pads can enhance feel for spirited riders.

At 119–137 kg (262–302 lbs), the Runner feels light on its feet, with a power-to-weight ratio of 0.12–0.17 HP/kg. The riding position is upright but sporty, and the floorboard provides ample legroom for taller riders. Wind protection is minimal on base models, but ST trims with optional windshields make highway jaunts more tolerable.
