2025 KTM 50 SX FACTORY EDITION – THE FIRST FACTORY TASTE FOR SAN DIEGO'S YOUNGEST RACERS

San Diego's motocross future starts here. The 2025 KTM 50 SX FACTORY EDITION is a no-compromise race machine built specifically for the youngest class of competitive riders. Designed with the same READY TO RACE spirit as KTM’s full-size Factory bikes, this mini-machine delivers true championship energy in a scaled-down package, setting up kids to experience real speed, real control, and real victories.

Powered by a race-tuned 49 cc 2-stroke engine and paired with an automatic centrifugal clutch, the 50 SX FACTORY EDITION makes racing accessible without sacrificing intensity. From Glen Helen’s mini track to weekend local series in El Cajon, young riders will gain valuable skills on a bike that handles like a professional machine thanks to its high-performance WP XACT suspension and rigid chromoly frame.

What sets this Factory Edition apart is the list of upgrades: FMF exhaust system, Dunlop Geomax MX53 tires, CNC aluminum components, and special Factory graphics that mirror the look of KTM’s pro fleet. With the 2025 KTM 50 SX FACTORY EDITION, there are no training wheels—just the thrill of speed, growth, and competition, built perfectly for the next SoCal moto legend.
