The SM450R is a derivative of Husqvarna's successful off-road motocross and enduro models (e.g., CR/WR series), adapted for street use with smaller wheels, street tires, and updated suspension/braking.
Manufacturing Location:
Sweden (traditional Husqvarna manufacturing base), although ownership has changed over the years, influencing production locations.
Industry Recognition:
Husqvarna motorcycles have a strong following and are recognized for their performance and off-road lineage. Specific awards for the SM450R in 2007-2008 would be subject to period reviews and publications.
Performance Reviews:
Generally praised for agile handling, strong engine, and braking, but often noted for a firm ride and demanding maintenance for optimal performance.
