Vehicle Information
Husqvarna FX 450 Dirt Bike (2017-2024)
The Husqvarna FX 450 (2017-2024) is a dedicated off-road competition motorcycle, renowned for its high-performance cross-country capabilities. Throughout these years, it has consistently featured a powerful single-cylinder, four-stroke engine with a 449.9 cc displacement. This model is typically offered as a singular, high-spec machine rather than in distinct trim levels. The FX 450 has undergone significant generational updates within this period. A new generation was introduced in 2019, bringing redesigned bodywork, a more rigid frame, a lighter subframe, and engine upgrades including a lighter cylinder head. A complete overhaul followed in 2023, featuring an all-new engine designed for mass centralization, a new chromoly steel frame, a hybrid subframe, and updated WP Xact suspension. Further suspension evolution occurred in 2024, replacing the air fork with a new WP Xact closed-cartridge coil-spring fork. Q: How do I ensure this product fits my Husqvarna FX 450?
A: Please use the year and edition selector at the top of the page to confirm compatibility for your specific model year.
