2026 KTM 350 SX-F

The 2026 KTM 350 SX-F is a "middle-ground masterclass" motocross bike with minor cosmetic and functional updates to its highly successful, existing platform. It features a "very orange" graphics scheme with black and purple accents and builds on the strong foundation introduced in 2023. The bike is designed to offer a blend of 250-like agility with 450-class power that is more manageable for a wider range of riders. 

Key features

• Engine: The 349.7cc, single-cylinder, four-stroke engine weighs just 60.6 lbs (27.5 kg), providing an excellent power-to-weight ratio. It is a high-revving engine that delivers usable power throughout the rev range.
• Chassis and frame: The frame is crafted from hydroformed, robot-welded chromoly steel, optimized for balanced comfort and control. Updates in 2025 made the chassis less rigid, and the 2026 model benefits from this improved flex and feel.
• Electronics: Standard features include a map-select switch for choosing between two engine maps, plus a launch control function and a quickshifter for clutchless upshifts from 2nd to 5th gear.
• Suspension: The bike is equipped with adjustable WP XACT suspension both front and rear, which can be adjusted by hand without tools.
• Styling: A striking new orange, blue, and black graphic scheme with a black seat cover gives the bike a fresh visual look for 2026. 

What's new for 2026

Since the bike received significant chassis updates in 2025, the changes for the 2026 model year are more incremental and focus on usability. 

• Radiator cap: A new threaded design allows for easier and faster opening with less force.
• Fuel connector: A new protective cap for the CPC fuel connector guards against damage and prevents accidental disconnections and dirt intrusion.
• Graphics: The bike sports a fresh "very orange" graphic design with accents of blue and purple.
• Wiring harness: Revised routing of the wiring harness and new fixing points improve durability and protection against mud and water. 

Rider profile

The KTM 350 SX-F is an excellent choice for a variety of riders:

• Amateurs and Vet riders: Many riders find the 350 SX-F easier and less tiring to ride than a full-sized 450, making it one of KTM's most popular models in this segment.
• Transitioning riders: It serves as a great bridge for riders moving up from a 250 to a 450.
• Aggressive riders: Those who like to ride with high engine RPMs will appreciate its quick-revving engine and high peak horsepower.
