KTM 50 SX FACTORY EDITION Features
KTM 50 SX FACTORY EDITION 2025

ADJUSTABILITY
Different adjustability options were built into the 2025 KTM 50 SX FACTORY EDITION's construction using scientific statistical data and young racers' input data. Finding the right fit for your little ripper is easy thanks to height-adjustable suspension, handlebar position, subframe, and bodywork, taking the seat height from a low setting of 634mm to a taller setting of 682mm.

KTM 50 SX FACTORY EDITION 2025

CARBURETOR
A proven Dell'Orto type PHBG 19 BS carburetor takes prime position in producing the goods in the 2025 KTM 50 SX FACTORY EDITION, with settings that work perfectly in harmony with the engine, exhaust, and air intake design. And specific to the KTM 50 SX FACTORY EDITION, the reed valve case features a "double stage" concept, with an additional set of membrane flaps for even better gas atomization.

KTM 50 SX FACTORY EDITION 2025

PERFORMANCE
The 2025 KTM 50 SX FACTORY EDITION features a modern and compact engine using the latest 2-stroke technology. Using a 3-shaft design, the crankshaft is positioned near the center of gravity, which benefits mass centralization and creates the ideal intake angle into the reed valve for top-level performance. An independent cylinder blank allows for a complete cylinder design, with increased power.

KTM 50 SX FACTORY EDITION 2025

TANK
With a tank design to compliment the frame concept and bodywork, the KTM 50 SX FACTORY EDITION is ready to fuel the fire in your little ripper.

KTM 50 SX FACTORY EDITION 2025

AIRBOX AND FILTER
The airbox concept features a conventional suction sleeve made from a hard-wearing polyamide instead of rubber and a Twin Air filter mounting system that features snap locks for easy and intuitive mounting. The Twin Air filter is also placed under the seat and is easily accessible without any tools by simply removing the seat. It also features improved dirt intrusion resistance, with no more dirt falling into the intake tract when changing the filter.

KTM 50 SX FACTORY EDITION 2025

HANDLEBARS & GRIPS
Hold on tight! The high-quality, tapered, black handlebar is made of lightweight aluminum alloy and ensures top stability, vibration damping, and control. The bend and profile is designed specifically to meet the needs of young riders, with factory-specific grey ODI grips on the left, with a vulcanized ODI grip on the right-side throttle assembly, adding to the overall quality. A crash pad on the handlebar protects the rider from any rough contact or impact with the bars.

KTM 50 SX FACTORY EDITION 2025

WHEELS AND TYRES
Rolling off the race rig and into the pit lane, the 2025 KTM 50 SX FACTORY EDITION uses lightweight, black anodized, aluminum rims like the full-size KTM SX range. These provide the highest levels of strength and reliability; DUNLOP Geomax MX53 tires deliver outstanding performance on any terrain and exceptional straight-line stability.

KTM 50 SX FACTORY EDITION 2025

FOOTPEGS
All-new, "no-dirt" footrests offer a bigger surface area for improved grip while standing on the pegs, and are less susceptible to hooking up in deep ruts, take-offs when scrubbing, or track barriers.

KTM 50 SX FACTORY EDITION 2025

EXHAUST
A complete FMF exhaust system consists of the nickel-plated FMF fatty pipe and the FMF Powercore 2 silencer, with a signature 'Braaaaap!'. A black anodized, CNC-machined exhaust flange takes care of the perfect integration of the FMF exhaust system.
