Overview

Introducing the 2019 Cobra CX50 JR, a standout minibike-cross machine designed specifically for young riders and aspiring motocross champions. Cobra has built a reputation for crafting high-performance bikes that meld agility with user-friendliness, and the CX50 JR is no exception. This model is tailored to provide budding riders with a robust platform to hone their skills, offering a perfect blend of lightweight design and powerful performance. With its sleek lines and vibrant color options in yellow, red, and gray, it not only looks the part but also stands out on the track. At the heart of the CX50 JR lies a spirited single-cylinder, two-stroke engine with a displacement of 50.00 ccm. This engine delivers responsive power, allowing young riders to accelerate with confidence while mastering their technique. The 39.0 mm bore and 41.7 mm stroke create a peppy power band, and the 14 mm carburettor ensures efficient fuel delivery for optimal performance. With a lightweight chassis tipping the scales at just 36.7 kg (81.0 pounds), this bike is agile and nimble, making tight turns and quick maneuvers feel effortless. The 1-speed gearbox paired with a Cobra 3Gx 3-shoe clutch offers smooth engagement, perfect for those just starting their motocross journey. What sets the CX50 JR apart is its thoughtfully engineered chassis and suspension system. Built on a double cradle 4130 CrMo steel frame, it provides durability while still being light enough for young riders to handle. The front and rear suspension travel of 170 mm, supported by advanced CARD technology, absorbs bumps with ease, ensuring a smooth ride over varied terrains. The dual disc brake system, featuring a 160 mm front and 140 mm rear disc, delivers excellent stopping power, instilling confidence in young riders as they tackle their first jumps and turns. With a ground clearance of 216 mm, the bike is well-equipped to handle off-road adventures while maintaining stability. **
