KTM 2026 SX Motocross Lineup Revealed – 10 New Bikes Launch the Summer Comeback!

After a relatively quiet year in 2025 due to internal financial struggles, KTM is roaring back to life with a bold return to the motocross scene. Under new ownership and with full production resumed, the Austrian manufacturer has just unveiled its refreshed 2026 SX range, marking the first major release under its summer offensive. And make no mistake, this is a statement of intent. KTM's SX range is legendary in motocross circles, and for 2026, the brand is offering 10 revitalized models designed to cater to riders of all ages and skill levels. These include the 50SX, 50SX Factory Edition, 65SX, 85SX, 125SX, 250SX, 300SX, 250SX-F, 350SX-F, and the flagship 450SX-F. While there are no changes to the engines, frames, or suspension systems, the updates target practical improvements and styling enhancements that make a noticeable difference in real-world use. The most eye-catching upgrade is the new factory-inspired color scheme. Still deeply rooted in KTM's signature orange, the 2026 bikes now feature striking purple highlights on the fuel tank spoilers and fort guards. The frame remains black, as does the seat, but the updated graphics evoke the aggressive visual identity seen on KTM's factory race bikes in the FIM Motocross World Championship and AMA Supercross series. All 10 bikes have received a redesigned radiator closure for easier maintenance access. Depending on the model, some also feature a new protector cap for the FuelLink QuickLock system, a thoughtful tweak that simplifies fuel system maintenance, especially in dusty or muddy conditions. For the two-stroke models, KTM has refined the wiring harness routing and fixing points, ensuring better reliability and compliance with new FIM noise regulations. Additionally, specific bikes like the 50SX and 65SX are now equipped with WP EXACT AER front forks engineered for improved damping and control. This is a notable upgrade for younger riders who need more responsive handling as they develop their off-road skills. In line with this, the 65SX and 85SX have been brought more in line with KTM's full-size bikes, adopting the same 17mm triple clamps with closed screw nut format. This prevents dirt and water intrusion, an essential improvement for motocross durability. The 65SX also gets a revised clutch fixation system and enhanced throttle cable assembly, reducing the chance of kinks and malfunctions. The 85SX, designed for riders transitioning from smaller bikes, includes a new rear brake lever with two adjustment settings, making it easier for different rider sizes to find the perfect fit. It's a small touch with a big impact on rideability. Perhaps most exciting is KTM's commitment to electronics and rider customization. The 2026 SX bikes are compatible with the Connectivity Unit Off-Road and the KTM Connect app, allowing riders to fine-tune traction control, engine mapping and suspension settings via smartphone. This level of tech, once reserved for pro racers, is now available to weekend warriors and aspiring champions alike. It's important to note that while these aren't full generational updates, the full-size SX bikes remain in their fourth generation, the 50SX in its third and the 85SX in its second. The 2026 updates are substantial enough to keep them competitive, desirable and race-ready. Starting in August 2025, these new models will begin hitting KTM dealers worldwide. Pricing will vary by region, so KTM encourages fans to check with local dealers for availability and cost. KTM also teased updates for the SX-E electric range, but those will be revealed later in the summer. For now, the 2026 SX lineup sets the tone. It's bold, refined and built for battle.
