Cagiva Roadster

The Roadster 521 is a 125cc motorcycle made by the Italian motorcycle firm, Cagiva in the 1990s.
One of the fastest accelerating 125cc motorcycles of its time, the Roadster 521 is known to have a top speed of 80 mph restricted and an estimated 100 mph+ un-restricted. Achieving approximately 70 miles per gallon, it is relatively economical for a 2-stroke motorcycle. In 2000, production of the Cagiva Roadster ended. In 2008, Harley-Davidson bought MV Agusta Motor, the parent company of Cagiva, thereby regaining some control of its old Aermacchi factory.
