Vehicle Information
Husqvarna FX 350 Dirt Bike (2017-2026)
The Husqvarna FX 350 (2017-2026) is a high-performance cross-country motorcycle renowned for its versatile 349.7cc liquid-cooled, DOHC, four-stroke, single-cylinder engine. Throughout its production, this model has consistently offered a blend of power and agility, with manufacturer-reported horsepower around 58 hp, and independent dyno tests showing rear-wheel figures between 49.1 hp and 51.0 hp. It's designed for riders seeking a competitive edge in off-road conditions. While the FX 350 generally maintains its core identity, notable updates have occurred. The 2019 model introduced revised bodywork and ergonomics. For 2024, new WP XACT forks improved damping. A significant evolution arrived in 2025 with a reworked, lighter chassis, revised swingarm, updated suspension settings, and an engine featuring a higher 14.6:1 compression ratio, updated gear ratios, and a quickshifter. A "Heritage" edition, primarily a styling package, was also offered in 2025. The 2026 model continued these advancements with further bodywork refinements and a white powder-coated frame.
