Overview

Introducing the 2018 Cobra CX50 JR, a standout in the world of minibike-cross motorcycles. Designed specifically for young riders eager to take their first steps into the exhilarating world of motocross, this model expertly balances power, agility, and user-friendly performance. With a price tag of $3,998, the CX50 JR is positioned as an accessible choice for parents looking to invest in their child's motorsport passion while ensuring safety and durability on the track. At the heart of the CX50 JR lies a responsive 50cc single-cylinder, two-stroke engine that delivers an impressive blend of power and precision. With a bore and stroke of 39.0 x 41.7 mm, this agile machine is engineered for spirited acceleration, making it perfect for both competitive races and casual trail rides. The liquid-cooled setup ensures optimal performance under varied weather conditions, while its carburettor fuel system and reliable Cobra 3Gx 3-Shoe clutch provide smooth power delivery and enhanced control. Riders can expect a thrilling experience, thanks to its 1-speed gearbox, which simplifies handling and allows younger riders to focus on mastering their skills without getting bogged down by complex shifting. The CX50 JR isn't just about raw power; it's equipped with features that enhance the overall riding experience. The double cradle 4130 CrMo steel frame offers exceptional durability, while the sophisticated suspension setup—front CARD 30mm USD and rear adjustable piggyback—ensures a comfortable and stable ride over rough terrain. With both front and rear disc brakes providing reliable stopping power, riders can navigate tight corners and sudden stops with confidence. The bike's lightweight design, at just 36 kg (79.4 lbs), paired with a seat height of 607 mm (23.9 inches), makes it an ideal fit for the smaller frames of budding motocross enthusiasts. **

Pros

  • Lightweight and Agile: Weighing in at 36 kg, the CX50 JR is easy for young riders to handle, promoting confidence and control.
  • Responsive Engine: The 50cc two-stroke engine provides a thrilling ride while remaining manageable for newer riders.
  • Durable Construction: The robust double cradle frame ensures longevity and withstands the rigors of off-road riding.

Cons

  • Limited Speed Options: The 1-speed gearbox may not provide the versatility some riders desire as they progress in skill.
  • Kick Start Only: Some users may find the kick start mechanism less convenient compared to electric start options available on other models.
  • Fuel Capacity: With a fuel tank of only 2.60 liters (0.69 gallons), longer rides may require more frequent refueling, which can be a hassle during extended playtime.
