Vehicle Information
Husqvarna FE 250 Dirt Bike (2014-2022)
The Husqvarna FE 250 is an enduro motorcycle renowned for its versatility and trail performance. Produced from 2014 to 2022, it features a lightweight, compact, and powerful 249.9 cc DOHC (Double Overhead Camshaft) four-stroke, single-cylinder engine with four valves per cylinder and electronic fuel injection. This model was engineered to deliver an agile and responsive riding experience, highly valued by enduro enthusiasts. While the FE 250 was offered as a single model without distinct 'trims' in the conventional sense, it received significant updates over the years. The 2017 model year brought a major overhaul, making the engine more powerful, lighter, and more compact, with a revised cylinder head, new camshafts, and a forged piston. The frame was also updated to a central double-cradle-type Chromoly steel with a carbon-fiber reinforced subframe. Further refinements followed in 2020, increasing the compression ratio and optimizing camshafts for improved performance and responsiveness. The 2021 models introduced a chromium-molybdenum steel frame with precisely engineered flex characteristics and advanced WP XPLOR and XACT suspension. Frequently Asked Questions (FAQ):
