KTM 50 SX

When the next step up is into the 50cc class, there is no better option than the most powerful 50cc out there. For 2024, the KTM 50 SX is built around an advanced steel frame, housing a powerful engine, a 35mm WP XACT AER fork, a WP XACT monoshock, and an advanced hydraulic Formula brake system. Simply put - it's the most advanced and READY TO RACE 50 cc mini-crosser available to your little racer. 

Adjustability

Different adjustability options were built into the 2024 KTM 50 SX 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, 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 key 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, with updated settings that work perfectly in harmony with the new engine, exhaust, and air intake design. 

Performance

The 2024 KTM 50 SX 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 not only benefits mass centralization but also 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 a 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 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. 

Ergonomics 

Mimicking the full-size KTM SX range, the KTM 50 SX 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. The front number plate incorporates plastic flaps to protect the lower triple clamps from roost, while 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.
