Overview

Introducing the 2013 KTM 50 SX Mini, a pint-sized powerhouse designed specifically for young riders eager to make their mark on the motocross scene. As one of the leading models in the minibike-cross category, the 50 SX Mini is engineered to deliver an exhilarating experience on the track while providing the stability and control that new riders need. KTM has a longstanding reputation for building high-performance motorcycles, and the 50 SX Mini is no exception, making it the perfect gateway for kids to transition from training wheels to the thrilling world of motocross. At the heart of the KTM 50 SX Mini is a robust single-cylinder, two-stroke engine with a displacement of 49 cc. This agile powerplant is designed for responsive performance, featuring a carburettor fuel system and an SELETTRA 2p D36 ignition that ensures smooth acceleration and quick throttle response. The bike's 1-speed gearbox paired with a centrifugal clutch allows young riders to focus on honing their skills without the complication of manual gear shifting. With liquid cooling and a well-tuned suspension system, the 50 SX Mini delivers a comfortable ride, enabling young riders to tackle jumps and turns with confidence. KTM has incorporated several key features and advanced technology into the 50 SX Mini, ensuring that it stands out in the competitive minibike market. The central tube frame constructed from chrome molybdenum steel provides exceptional durability while keeping the bike lightweight at just 40.5 kg (89.3 pounds). Equipped with WP Suspension up front and in the rear, the bike boasts 100 mm (3.9 inches) of front travel and an impressive 171 mm (6.7 inches) of rear travel, allowing for superior handling on rough terrain. Additionally, the combination of a single disc brake system at both the front and rear ensures reliable stopping power, giving parents peace of mind while their kids ride. **
