Brand Origin:
Husqvarna Motorcycles, a Swedish brand with a long history dating back to 1903, known for its off-road prowess. Acquired by Cagiva in 1987, then by BMW in 2007, and later by Pierer Mobility AG (KTM).
Sm Series Development:
The SM series evolved from Husqvarna's successful off-road enduro and motocross platforms, adapting them for street use with larger wheels, street tires, and updated suspension settings. The 2007-2008 models represent a significant phase of development in this lineage.
Manufacturing Location:
Typically Italy during the Cagiva ownership era (pre-BMW acquisition). Manual might offer insights into specific production batches.
