Overview

### 2011 KTM 50 SX: The Ultimate Minibike-Cross Experience The 2011 KTM 50 SX stands as a paragon in the minibike-cross category, engineered specifically for young riders eager to conquer the track. With its striking orange, black, and white aesthetics, the 50 SX not only looks the part but delivers performance that’s second to none in its class. This bike is a perfect entry-point for aspiring motocross champions, featuring a lightweight design and a user-friendly setup that promotes confidence and skill development on dirt tracks. KTM has built a reputation for high-performance machines, and the 50 SX continues that legacy, making it an ideal choice for those ready to take their first steps into competitive riding. At the heart of the 2011 KTM 50 SX is a spirited 49cc single-cylinder, two-stroke engine that offers exhilarating performance for its size. With a bore and stroke of 39.5 x 40.0 mm, this compact powerhouse delivers impressive torque and responsiveness, thanks to the well-tuned DELL’ORTO PHBG 19 BS carburettor. The liquid-cooling system ensures optimal performance even during intense rides, while the automatic gearbox and adjustable centrifugal clutch make it easy for younger riders to focus on mastering their skills without the hassle of manual shifting. The overall riding experience is characterized by nimble handling and quick acceleration, giving riders the thrill they crave while allowing them to build their confidence on two wheels. KTM outfits the 50 SX with advanced features that enhance both safety and performance. The double-cradle-type frame is designed for strength and stability, while the Marzocchi front suspension and WP mono shock in the rear offer a plush ride, absorbing bumps and ensuring smooth handling on varying terrain. With a ground clearance of 252 mm and adjustable seat height starting at 684 mm, the bike caters to a range of young riders, making it versatile for different skill levels. The 160 mm front and 140 mm rear disc brakes provide reliable stopping power, crucial for both safety and performance on the track. It's a machine that seamlessly combines cutting-edge technology and practical design, ensuring that every ride is both fun and safe. **
