Here is a brief description courtesy from “Classic Motorcycles”:
"“Badge engineering” is a familiar term in the automobile industry, loosely defined as the rebadging of one make and model to create another. Think of a Chrysler sedan from the Eighties, and it will undoubtedly have one or two nearly identical siblings. And while this is the kind of marketing one might expect from decades past in Detroit, it wasn’t common in Bologna, even during their toughest times.
In 1985, Ducati had just been purchased by Cagiva. Cagiva, then the largest Italian motorcycle manufacturer, was primarily making mopeds and small street bikes at the time, and many of them were two-strokes. To expand into the middle- and heavyweight street bike market, it needed four-stroke engines. As the March 1985 issue of Rider magazine said, “There were several reasons why Ducati’s engine manufacturing facility was the logical candidate to supply Cagiva with motors: The physical plant was already there, the product was good, and it was the only segment of Ducati’s operation that had been profitable.”
Cagiva’s owners, the Castiglioni brothers, had a new direction in mind for the company, and it included widening the scope of the company’s products beyond that of just sport bikes for enthusiasts. Two years before Cagiva purchased Ducati, Ducati had agreed to supply engines to Cagiva for two models, the Elefant dual-sport bike and the Alazzurra, a bike very similar to the earlier Ducati Pantah. It was 1985 before the two bikes hit the production line.
The 650cc Alazzurra was essentially the latest version of the Ducati Pantah when it debuted in 1985"
