Racing creates emotion and fans, and this passion for competition and excellence can start at any age. The KTM 50 SX FACTORY EDITION is our nod to the future of the sport. Count on full READY TO RACE consideration with an advanced steel frame and an engine that won't disappoint. The bike boasts leading components such as DUNLOP Geomax MX53 tires, a FMF exhaust system, a new 35 mm WP XACT AER fork, a WP XACT monoshock, and a reworked hydraulic Formula brake system. All this, along with key similarities with the full-sized motocross range, superior levels of quality, and revolutionary height adjustability included. Don't forget those astonishing looks for the full 'factory' treatment.
Now available at Lings Powersports, the KTM 50 SX Factory Edition brings authentic factory-style upgrades to KTM’s smallest motocross platform, delivering precision, confidence, and a taste of pro-level design for junior riders.
At its core, the bike is powered by a peppy 49 cc single-cylinder, air-cooled two-stroke engine. Automatic centrifugal clutch technology gives young riders intuitive power delivery while allowing smooth, hands-free engagement—ideal for building throttle control and cornering comfort.
The chassis is a reinforced mini steel frame tailored to withstand fierce junior riding. It features a Factory Edition-specific WP APEX rear shock and spring, offering race-grade damping performance and improved body control during jumps and berm attacks. The long-travel fork—matched to Factory-level specification—soaks up impacts cleanly and encourages aggressive progressions.
Scaled-down, yet purposeful, the bike rolls on small 10″ wheels fitted with grippy off-road tyres. Designed for confidence and predictability, the suspension and wheel setup enable young racers to handle both twisty tracks and straight-line acceleration with ease.
Stopping power comes from precise front and rear hydraulic disc brakes sized for mini bikes. Paired with the automatic clutch, braking transitions become intuitive and teachable—helping new riders learn skills quickly and safely.
Factory Edition styling accents include vibrant graphics, anodized fork guards, a branded number panel frame, and Factory paint highlights that mirror KTM’s adult race bikes. These visual upgrades add authenticity and pride from the fueling stage to the podium.
With lightweight agility, polished handling, and factory-level kit, the KTM 50 SX Factory Edition offers young riders a premium introduction to motocross—ready to build skills while looking every part the future champion.
