The Husaberg FC 501 is a four-stroke motocross bike from Husaberg, the Swedish maker founded in 1988 by former Husqvarna engineers. It uses a liquid-cooled 501cc single in a light chassis, far lighter than most big four-strokes of its time.
It helped prove that four-strokes could compete in motocross. Husaberg was bought by KTM in 1995.
