About Husqvarna

Country of Origin: Sweden (modern production in Austria/Europe under Pierer Mobility)
Founder: Husqvarna Vapenfabriks AB (17th-century origins; motorcycles early 1900s)
Best Known For: MX/enduro dominance (CR/WR/FE), sleek street models (Vitpilen/Svartpilen), and rally success

Company History

Husqvarna’s motorcycle chapter began in the brass era, but its legend was forged in the dirt: light, sharp two-strokes that ruled motocross in the 1960s–70s and taught the world that weight is the enemy. The brand’s minimalist Swedish design language—clean lines, purposeful ergonomics—carried into modern four-strokes and, after ownership changes, into a new life within Pierer Mobility. MX and enduro ranges share platforms with KTM but wear unique ergonomics, suspension settings, and aesthetics—white/blue bodywork, lower seat heights on some models, and a refined feel. On the street, Vitpilen/Svartpilen distilled Scandinavian design into flickable singles and twins that made city riding artful. Rally programs and off-road championships kept Husky’s credentials current. Historically, Husqvarna is a throughline from the sport’s origins to today’s electronics-assisted dirt bikes: a brand that made ‘light and right’ doctrine mainstream. Whether a 1970s silver-tank two-stroke or a modern FE, a Husky feels like a precise tool—ready to turn terrain into flow.
