2026 KTM 50 SX

Fitted with a digital ignition the with improved processing power 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 key advantage. The throttle cable assembly benefits from a new stabilization cap that extends the lifetime of the cable by reducing the risk of kinking and damage.

A proven Dell'Orto type PHBG 19 BS carburetor takes a prime position in producing the goods in the KTM 50 SX, that works perfectly in harmony with the engine, exhaust, and air intake design.

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

The KTM 50 SX is fitted with a 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 extra durability, wear, and consistent performance. The clutch itself receives a boost in quality with a high-strength pre-coat and increased tightening torque for reliable fastening of the whole assembly.

There's no more worrying about breaking the plug, thanks to the KTM 50 SX featuring a spark plug from BRISK with a longer thread. Also, thanks to this innovation, the part number is printed on the spark plugs for easy reading.

Mimicking the full-size KTM SX range, the KTM 50 SX features the same advancements found in the larger KTM SXs. 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. The front number plate incorporates plastic flaps to protect the lower triple clamps from roost. Speaking of triple clamps, the model spectrum now has an improved fixing mechanism which hikes the lifespan of the steering head bearings thanks to the extra block from dirt and water. The wrench size is also smaller and more practical. 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.

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 an 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.

The KTM 50 SX boasts a high-strength chromium molybdenum steel frame design with forged connecting parts integrated into the frame. This together with carefully calculated parameters of longitudinal flex and torsional rigidity, allow tailormade stiffness and an unprecedented quality of the Mini frame could be achieved. 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.

A "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.

Featuring the latest in suspension technology, the KTM 50 SX has an updated 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. The upgrade means better damping and control and is a step forward for the suspension performance. At the rear, fully-adjustable WP XACT monoshock boasts a mounting point on the frame making it more compact, providing the perfect balance and damping characteristics to match the fork.

Featuring the same level of technology offered on the full-size KTM SX range, the KTM 50 SX is fitted with hydraulic brake calipers and state-of-the-art front and rear waved 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.

The KTM 50 SX has state-of-the-art Pankl radiators inspired by the full-size KTM SX range and features the same basic design with all the hardcore cooling properties. The KTM 50 SX 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 and the tank spoilers to channel air through the cooling fins efficiently.

Keep track of engine hours easily, 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 fowling up the display.
