2024 KTM 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 an even more powerful engine, a 35 mm WP XACT AER fork, a WP XACT mono-shock, 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 24.9 inches (634 mm) to a taller setting of 26.8 inches (682 mm).

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 increased power.

Suspension

Featuring the latest in suspension technology, the KTM 50 SX is fitted with 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, rider weight, or track conditions. At the rear, an all-new fully-adjustable WP XACT monoshock boasts new mounting points on the frame, making it more compact, and 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 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.
