(December 9, 1920 - February 10, 2007 )
In 1949 he won the inaugural 250cc World Championship riding for the Italian Moto Guzzi factory. During the 1950 season, Ruffo was annoyed that Moto Guzzi instructed him to let his team-mate win the Championship that year while he finished third. That same year, Ruffo rode a Mondial to claim the 125cc World Championship. In 1951 he once again captured the 250cc World Champion with four victories. Ruffo retired in 1952 after an accident and opened a successful vehicle hire business in Verona. He died at 86 years old.
