Produktinfo

Power Supremacy

KTM’s FACTORY EDITIONs are the result of years of developing Factory Race machines for some of the fastest riders on the planet competing on some of its most challenging terrain. Junior riders and racers that climb on the KTM 50 SX FACTORY EDITION can do so in the knowledge that they are experiencing class-leading performance with state-of-the-art WP Suspension, high-end brakes and minimal weight. The 2021 KTM 50 SX FACTORY EDITION boasts several upgrades with reworked jetting, a smaller rear sprocket and a revised clutch springs configuration for easier operation. A new aesthetic means a FACTORY EDITION graphics package, orange/black chain guard, CNC machined clutch and ignition covers, grey grips and a blue seat to enhance that ‘works’ bike appeal. An FMF exhaust system also denotes the bike’s status as an unmissable front-runner on the track.

The high performance 2-stroke engine is extremely compact and powerful, setting the standard in the highly competitive 50 cc class. Its 3-shaft design positions the crankshaft very close to the center of gravity, offering exceptional handling. This design provides a flow-optimized intake angle into the reed valve, which results in impressive performance across the rpm range. Orange anodized CNC machined aluminum clutch and ignition covers provide excellent heat dissipation, durability and, of course, highlight this machine’s racing DNA. The multidisc automatic clutch developed by KTM provides controllable acceleration and makes riding this motorcycle as easy as twisting the throttle. The KTM 50 SX FACTORY EDITION features a special clutch configuration for enhanced power delivery, combining extremely agile handling with maximum performance. The clutch can also be easily adjusted to the rider’s personal needs or the specific requirements of each individual track within minutes and with no special tools required. A reworked carburetor setting in conjunction with the new engine set up works together with a smaller rear sprocket which makes the bike even faster.
