Overview

Introducing the 2014 KTM 50 SX, a pint-sized powerhouse specifically designed to ignite the passion for motocross in young riders. Positioned as a top-tier entry-level motocross bike, the 50 SX is engineered to provide the perfect blend of performance, agility, and rider-friendly features. KTM's renowned racing heritage is encapsulated in this model, making it an ideal choice for budding motocross enthusiasts eager to tackle their first tracks and trails with confidence. With its striking orange and black color scheme, the 50 SX is as visually appealing as it is capable, turning heads both on and off the track. At the heart of the 2014 KTM 50 SX is a spirited 49cc single-cylinder, two-stroke engine, designed for maximum responsiveness and exhilarating power delivery. With a bore and stroke of 39.5 x 40.0 mm, this little engine is engineered to strike the perfect balance between torque and acceleration, ensuring a thrilling ride on any terrain. The liquid cooling system and SELETTRA ignition system work in harmony to keep temperatures in check, while the automatic centrifugal clutch allows young riders to focus on mastering their skills without the hassle of manual clutch operation. This combination not only enhances control but also provides a smooth, predictable power band that young riders can handle with ease. The 50 SX's chassis is a marvel of engineering, featuring a robust chrome molybdenum steel frame that provides exceptional rigidity while remaining lightweight at just 39.8 kg (87.7 pounds). The WP suspension system, complete with a 205 mm front travel and 185 mm rear travel, absorbs bumps and ruts with ease, instilling confidence in riders as they navigate challenging terrain. With advanced braking systems, including a 160 mm front and 140 mm rear disc setup, the 50 SX ensures precise stopping power when it’s needed most, allowing young riders to push their limits safely. The bike's adjustable seat height of 684 mm (26.9 inches) accommodates growing riders, making it a versatile choice for those just starting their motocross journey. **

Pros

  • Lightweight and Agile: Weighing in at just 39.8 kg, the 50 SX is easy for young riders to handle, offering a nimble and responsive riding experience.
  • User-Friendly Power Delivery: The automatic clutch and smooth power band allow riders to focus on their technique without the added complexity of manual clutch engagement.
  • Advanced Suspension and Braking: Equipped with high-quality WP suspension and strong disc brakes, the 50 SX delivers exceptional stability and control, even on rough terrain.

Cons

  • Limited Fuel Capacity: With a fuel tank of just 2.30 liters (0.61 gallons), riders may find themselves refueling frequently during longer rides.
  • Two-Stroke Maintenance: While two-stroke engines are known for their power, they can require more frequent maintenance and mixing of oil and fuel, which may be challenging for novice riders and their parents.
  • Not Suitable for Adult Riders: Designed specifically for young riders, the 50 SX's size and power output limit its appeal to beginners, making it unsuitable for older or more experienced riders looking for performance.
