Overview

Introducing the 2012 Cobra CX50 Junior, a remarkable minibike-cross machine designed specifically for young riders eager to take on the dirt track with confidence and flair. Known for its lightweight design and impressive performance, this model has carved a niche in the competitive world of youth motocross. With a perfect blend of power, agility, and rider-friendly features, the CX50 Junior paves the way for the next generation of motocross enthusiasts to experience the thrill of racing at an early age. At the heart of the CX50 Junior lies a robust 50cc single-cylinder, two-stroke engine that delivers exhilarating performance with every twist of the throttle. The engine's compact bore and stroke dimensions (39.0 x 41.7 mm) allow it to produce a thrilling powerband that's both responsive and easy to manage for younger riders. The liquid cooling system ensures optimal performance even during the most intense sessions, while the carburettor fuel system provides the perfect mixture for spirited rides. With a simple 1-speed gearbox and a reliable chain final drive, the CX50 Junior is designed to keep young riders focused on honing their skills without the complexities of shifting gears. The CX50 Junior's chassis and suspension are engineered for maximum stability and control, featuring a double cradle frame made from durable 4130 CrMo steel. This robust construction supports the bike's lightweight profile (just 36.7 kg or 81.0 pounds) while ensuring durability on rugged terrain. With 170 mm of travel on both the front and rear suspension—thanks to the CARD 30mm USD front forks and adjustable piggyback rear shock—young riders will experience superior handling and comfort, whether navigating tight corners or tackling jumps. The bike’s well-designed braking system, featuring a 160 mm front disc and a 140 mm rear disc, provides reliable stopping power, instilling confidence in every ride. **
