Key specifications
Overview
Introducing the 2008 Derbi Dirt Kid 50, a standout contender in the minibike-cross category, designed specifically for young riders and those new to the world of off-road biking. With its lightweight frame and compact dimensions, this bike is tailored for agility and maneuverability, making it an ideal choice for navigating tight trails or tackling backyard jumps. The Dirt Kid 50 captures the essence of dirt biking while providing a user-friendly experience, making it a perfect entry point for budding motocross enthusiasts. At the heart of the Dirt Kid 50 lies a peppy 49.90cc single-cylinder, four-stroke engine that delivers spirited performance without overwhelming novice riders. The bike’s air-cooled design ensures consistent operation, while the carburettor fuel system optimizes power delivery for a smooth ride. With a 1-speed gearbox and wet housing clutch, transitioning between power and control is seamless, allowing riders to focus on mastering their skills. The handling is further enhanced by a lightweight construction of just 47.0 kg (103.6 pounds), making it easy to maneuver over obstacles and through tight turns. The Derbi Dirt Kid 50 is not just about power; it’s packed with features that enhance both safety and comfort. The double steel beam frame offers durability and stability, while the hydraulic front fork and monoshock rear suspension—boasting 135 mm and 160 mm of travel, respectively—provide superior shock absorption on rugged terrain. The braking system is equally impressive, with a single 160 mm disc brake up front for responsive stopping power and a reliable drum brake at the rear. With a seat height of 685 mm (27.0 inches), it caters to younger riders, ensuring they can plant their feet firmly on the ground when needed. **
