Vehicle Information
KTM 350 EXC-F Motorcycle - Dual-Sport (2012-2026)
The KTM 350 EXC-F, a prominent model in KTM's enduro lineup from 2012 to 2026, is celebrated for its versatility and performance. This robust off-road motorcycle consistently features a 349.7 cc (often rounded to 350cc) single-cylinder, four-stroke engine, delivering a balanced blend of power and agility suitable for various terrains. While maintaining its core identity, the 350 EXC-F has undergone significant evolutions. A major engine redesign in 2017 made it more compact and lighter, improving mass centralization. The 2024 model year marked an all-new generation, introducing a redesigned chassis and an engine tilted backward with a repositioned sprocket for enhanced performance and center of gravity. This generation also brought a new ultra-light subframe and advanced WP suspension components. Further refinements in 2025 included a new Offroad Control Unit (OCU), and 2026 saw updated damping settings for the WP XACT fork. Special trims like the "Six Days" edition have been consistently available, alongside the "Champion Edition" for 2025, offering enhanced features. Horsepower figures have evolved, with early models producing "over 45 hp" and the 2024 model boasting a "51 horsepower punch". Q: Is this part compatible with my specific KTM 350 EXC-F model?
