Adjustablity

The KTM 50 SX FACTORY EDITION is designed to grow with the little racer, by being height adjustable. Different options were built into the KTM 50 SX construction using scientific statistical data and mannequins. So, finding the right fit for your junior ripper is ultra 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

Fitted with digital ignition, the KTM 50 SX FACTORY EDITION has a primed power and 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 roster, adds a vital advantage to the digital ignition package. The throttle cable assembly benefits from a stabilization cap that extends the lifetime of the cable by reducing the risk of kinking and damage.

Carburetor

A proven Dell'Orto type PHBG 19 BS carburetor produces the goods in the KTM 50 SX FACTORY EDITION, with settings that work perfectly in harmony with the engine, exhaust, and air intake design. Specific to the KTM 50 SX FACTORY EDITION, the reed valve case has a 'double stage' concept, with an additional set of membrane flaps for even better gas atomization.

Performance

The KTM 50 SX FACTORY EDITION boasts a modern and compact engine with 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 plenty of power.

Power-Reduction Kits

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

RACE-MATIC

Clutch

The KTM 50 SX FACTORY EDITION is fitted with a automatic centrifugal clutch reducing the complexity for younger riders, and helps 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 tough clutch basket provides Improved durability, wear, and consistent performance. The clutch itself has a high-strength pre-coat and increased tightening torque for reliable fastening of the whole assembly. This being the FACTORY EDITION, it also gets a 'bling' HINSON Racing CNC machined outer clutch cover for added punch.

Spark Plug

Don't worry about breaking the plug: the KTM 50 SX FACTORY EDITION has a Iridium-type spark plug from BRISK with a longer thread and a factory orange sparkplug connector. Also, thanks to this addition, the part number is printed on the spark plugs for easy reading.

Airbox and Filter

The airbox features a conventional suction sleeve made from hard-wearing polyamide instead of rubber, and a Twin Air filter mounting system that has snap locks for easy and intuitive mounting. The Twin Air filter is placed under the seat and is easily accessible without any tools by simply removing the seat. It is more resistant to dust and dirt and the intake tract won't get affected when changing the filter.

Ergonomics

Mimicking the full-size KTM SX range, the KTM 50 SX FACTORY EDITION proudly claims the same advancements. Slim, sleek, and better suited to standing on the pegs, the side panels work much better with young riders' boots, allowing a proper squeezing of the bike with the knees when standing up. The front number plate incorporates plastic flaps to protect the lower triple clamps from roost. Speaking of triple clamps, the model spectrum has a clever fixing mechanism which hikes the lifespan of the steering head bearings thanks to being an extra barrier from dirt and water. The wrench size is small and practical. The tank spoiler features a bicomponent technology with 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.

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 a factory-specific grey ODI grip on the left, and 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

The KTM 50 SX FACTORY EDITION is wrapped by a high-strength chromium molybdenum steel frame design with forged connecting parts integrated into the unit. This together with carefully calculated parameters of longitudinal flex and torsional rigidity, allow tailormade stiffness and unprecedented quality. The frame layout features a typical MX design without any cross tube behind the steering head. Like our full-size models, the rear shock mount is separated from the main upper frame tube. The frame also comes with frame protectors as standard.

Wheels & Tires

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

Suspension

The KTM 50 SX FACTORY EDITION has a state-of-the-art, lightweight 35 mm USD WP XACT AER fork. With 205 mm 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. This means better damping and control. At the rear, a fully-adjustable WP XACT monoshock is compact and fixed at a single point on the frame, 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 KTM 50 SX FACTORY EDITION is fitted with hydraulic brake calipers and waved, state-of-the-art front and rear brake discs.

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. The flange gasket ensures durability and the exhaust valve ventilation is another notable spec. The unit is 'bulletproof' thanks to extra efficient and locally sourced manufacturing at KTM HQ.

Radiator

The KTM 50 SX FACTORY EDITION has state-of-the-art Pankl radiators inspired by the full-size KTM SX range and features the same design with all the hardcore cooling properties. The KTM 50 SX FACTORY EDITION uses one large radiator with more capacity instead of two smaller separate ones. This concept allows for optimized integration of the radiator into the frame and the tank spoilers to channel air through the cooling fins efficiently.

Hour Meter

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