Adjustablity

Different adjustability options were built into the 2024 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.

Ignition

A new digital ignition finds its way onto the 2024 KTM 50 SX FACTORY EDITION, with improved processing power and an all-new ignition curve, making for a cleaner burn and smoother power delivery. Individual ignition timing across the entire rpm range, just like that found on the full-sized KTM SX range, adds a vital advantage to the digital ignition. Ignition timings are also new, matching the revised engine layout, longer stroke, and other updates.

Carburetor

A proven Dell'Orto type PHBG 19 BS carburetor takes prime position in producing the goods in the 2024 KTM 50 SX FACTORY EDITION, with updated settings that work perfectly in harmony with the new 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.

Performance

The 2024 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 completely new cylinder design, with power peaking at 15hp.

Power-Reduction Kits

For absolute beginners, the KTM POWERPARTS catalog now offers a choice of two power-reduction kits. The first allows for an entry-level, moderate, and controllable power reduction to 4hp, with the second allowing for a more intermediate power kit unleashing 8hp for mid-level riding levels.

Clutch

The 2024 KTM 50 SX FACTORY EDITION is fitted with an updated and reworked automatic centrifugal clutch reducing the complexity for younger riders, and helping to boost riding confidence. The multi-disc clutch delivers a precise and predictable power delivery across the RPM range. It can be set to suit rider preferences or track conditions without using any special tools. Also, a reinforced clutch basket provides Improved durability, wear, and consistent performance. But this being the FACTORY EDITION, it also gets a 'bling' HINSON Racing CNC machined outer clutch cover for added visual punch.

Spark Plug

There's no more worrying about breaking the plug, thanks to the 2024 KTM 50 SX FACTORY EDITION featuring a new Iridium-type spark plug from BRISK with a longer thread and a factory orange sparkplug connector. Also, thanks to this innovation from BRISK, the part number is printed on the spark plugs for easy reading.

Tank

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

Airbox and Filter

An all-new airbox concept features a conventional suction sleeve made from a hard-wearing polyamide instead of rubber and a Twin Air filter mounting system that now 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.

Ergonomics

Mimicking the full-size KTM SX range, the KTM 50 SX FACTORY EDITION features the same advancements found in the larger KTM SX range. Slimmer, sleeker, and better suited to standing on the pegs, the side panels now work much better with young riders' boots, allowing a proper squeezing of the bike when standing up with the knees. The front number plate incorporates plastic flaps to protect the lower triple clamps from roost. At the same time, the tank spoiler features a bicomponent technology featuring the KTM-specific texture on the upper part. Side number plates are kept as close to the frame as possible, with the general seat line sitting slightly flatter compared to the old generation.

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. An entirely new 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.

Frame

Right, this is a big one. For the first time ever on a 50cc, the 2024 KTM 50 SX FACTORY EDITION boasts an all-new high-strength chromium molybdenum steel frame design with forged connecting parts. These, together with carefully calculated parameters of longitudinal flex and torsional rigidity, and incorporated sheet metal parts that allow tailormade stiffness, an unprecedented quality of the Mini frame could be achieved. The new frame layout features a typical MX design without any cross tube behind the steering head. The rear shock mount is separated from the main upper frame tube like on our full-size models. The frame now also comes with frame protectors as standard.

Wheels & Tires

Rolling off the race rig and into the pit lane, the 2024 KTM 50 SX FACTORY EDITION uses lightweight, black anodized, GIANT 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.

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.

Suspension

Featuring the latest in suspension technology, the KTM 50 SX FACTORY EDITION is fitted with a state-of-the-art, lightweight 35mm USD WP XACT AER fork. With 205mm of wheel travel, the air unit in the left fork leg can also be adjusted easily using an air pump for rider preference, weight, or track conditions. At the rear, an all-new fully-adjustable WP XACT monoshock boasts a new mounting point on the frame making it more compact, providing the perfect balance and damping characteristics to match the fork.

Brakes

Featuring the same level of technology offered on the full-size KTM SX range, the 2024 KTM 50 SX FACTORY EDITION is fitted with dramatically improved hydraulic brake calipers and waved, state-of-the-art front and rear brake discs. This system ensures advanced braking feel and unmatched stopping performance in all conditions, specifically on wet or muddy tracks, with improved durability and brake pad longevity.

Exhaust

A completely new FMF exhaust system consists of the nickel-platted 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.

Radiator

Featuring state-of-the-art technology and superior cooling power, the 2024 KTM 50 SX FACTORY EDITION uses one large radiator with more capacity instead of two smaller separate ones. This concept allows for better integration of the radiator into the frame, the tank spoilers channeling air through the cooling fins efficiently.

Hour Meter

Keep track of engine hours easily, with an hour meter now mounted at the same position behind the front number plate - as on the full-size models. This makes for easier reading and has a lower risk of dirt and water fowling up the display.

Graphics

The 2024 KTM 50 SX FACTORY EDITION features a KTM Red Bull Factory Racing-inspired color scheme, with much of the bodywork finished in orange with blue accents - much like those found on the full-size Factory Editions. Of course, sponsor logos, grey ODI lock-on grips, and an orange factory seat rounds off the package, making this 50cc weapon look as fast as it gets off the line.
