Vehicle Information
Husqvarna FE 501 Dirt Bike (2014-2026)
The Husqvarna FE 501 (2014-2026) is a versatile enduro and dual-sport motorcycle, known for its powerful single-cylinder, four-stroke engine, consistently around 510cc. Over its production run, the FE 501 has seen significant updates. Major generational shifts occurred in 2017 with an overhauled, lighter engine, in 2020 with a new frame, subframe, bodywork, and a more compact engine, and again in 2024 with a new, lighter engine positioned for improved mass centralization and updated chassis/suspension. Trims primarily differentiate between the off-road FE 501 and the street-legal FE 501S, with the FE 501w introduced in 2024 as an off-road compliant version of the dual-sport. FAQ:
