Overview

Introducing the 2010 Cobra CX50 JR, a pint-sized powerhouse designed specifically for the young and aspiring motocross champions. As a standout entry in the minibike-cross category, the CX50 JR has earned a solid reputation for its performance, durability, and ease of handling. Built with the budding racer in mind, this bike strikes an ideal balance between agility and power, making it the perfect stepping stone for young riders looking to hone their skills on the track. With an eye-catching color palette of yellow, red, and black, the CX50 JR doesn't just perform; it also makes a bold statement wherever it roams. At the heart of the CX50 JR lies a spirited 50cc single-cylinder, two-stroke engine that delivers impressive acceleration and throttle response. With a bore and stroke of 39.0 x 41.7 mm, this compact powerhouse is engineered for optimal performance, ensuring that young riders can tackle corners and straights with confidence. The liquid-cooled engine is paired with a carburettor fuel system and a simple 1-speed gearbox, allowing for seamless power delivery without the complexity of multiple gears. The lightweight frame, weighing in at just 36.7 kg (81.0 pounds), ensures that the bike is easy to maneuver, giving riders the ability to control their trajectory with finesse. The CX50 JR is built tough, featuring a robust double cradle frame constructed from 4130 CrMo steel for maximum durability. The bike is equipped with a Marzocchi 32mm front suspension that offers 160 mm of travel, complemented by the Öhlins piggyback rear suspension that provides an impressive 170 mm of travel, absorbing bumps and ensuring a smooth ride on any terrain. The braking system, featuring a single 160 mm disc in the front and an expanding drum brake in the rear, offers reliable stopping power, crucial for young riders learning their limits. The adjustable seat height of 607 mm (23.9 inches) and generous ground clearance of 216 mm (8.5 inches) further enhance rider comfort and control, allowing for a customized fit as they grow. **

Pros

  • Lightweight and Agile: At 36.7 kg, the CX50 JR is easy for young riders to handle, allowing for quick maneuverability and confidence on the track.
