Overview

Introducing the 2022 KTM 50 SX, the epitome of minibike-cross excellence designed specifically for young riders aged 4 to 10 years. With a competitive MSRP of $4,449, this pint-sized powerhouse stands tall in the realm of mini motocross motorcycles, combining durable construction with race-ready performance. KTM has long been a name synonymous with quality and innovation, and the 50 SX is no exception. Whether your little one is hitting the local dirt track or just exploring the great outdoors, this bike brings a thrilling experience that fosters confidence and skill development for the next generation of motorsport enthusiasts. At the heart of the KTM 50 SX lies a spirited 49cc engine, delivering an exhilarating ride while remaining manageable for young riders. The 2-stroke engine boasts a bore and stroke of 39.5 x 40.0 mm, paired with a centrifugal clutch that allows for smooth acceleration without the complexity of manual shifting. The automatic gearbox ensures that even novice riders can focus on mastering their techniques without worrying about gear changes. The bike’s lightweight construction, weighing in at just 41.5 kg (91.5 pounds), combined with a power-to-weight ratio that is simply unmatched in its class, allows for nimble handling and quick response, perfect for those tight corners and jumps that will challenge and excite young riders. The 2022 KTM 50 SX isn’t just about raw power; it’s packed with features designed for safety and ease of use. The central-tube frame with a double-cradle design provides exceptional stability, while the XACT WP suspension system—featuring a 35 mm upside-down fork in the front with 205 mm of travel and a rear mono shock with 180 mm of travel—absorbs bumps and enhances control on rough terrain. Stopping power is delivered through reliable single disc brakes both front and rear, ensuring young riders can confidently slow down when needed. The bike’s adjustable seat height, starting at just 665 mm (26.2 inches), makes it accessible for riders of varying heights, allowing for a perfect fit and comfort while tackling those thrilling rides. **

Pros

  • Lightweight and Maneuverable: At 41.5 kg, the bike is easy for young riders to handle, enhancing their confidence and control.
  • Automatic Gearbox: The automatic transmission simplifies the riding experience, allowing kids to focus on steering and balance.
  • Exceptional Suspension System: With high-quality WP suspension components, the bike offers superior handling and can absorb rough terrain effortlessly.

Cons

  • Limited Power for Advanced Riders: As a beginner bike, its 49cc engine may not satisfy more experienced young riders looking for a challenge.

  • Small Fuel Capacity: With only 2.30 liters (0.61 US gallons) of fuel capacity, riders may need to refuel often during longer practice sessions or races.
