In 1985 Guy Ligier, a French motorcycle racer and formula one car racer, built a Paris-Dakar competitor in collaboration with Cagiva who had recently taken control of the Ducati factory. The fuel tank of the 750cc twin carried 60 litres, sufficient for 600km. It was named the Cagiva Ligier.
Previously, Ligier had been a professional Rugby player. When that career ended, he switched to motorcycle racing, winning the 500cc French Motorcycle Championship on a Norton Manx in 1959 and 1960.
He also built sports cars, microcars and ATV quads, and later formula one cars.
