Silvio Grassetti (24 February 1936 – 9 September 2018) was an Italian professional Grand Prix motorcycle road racer.[1]
Grassetti was born in Montecchio, Sant'Angelo in Lizzola. The son of a Benelli employee, he began his racing career as a privateer Benelli racer. He made his Grand Prix debut as a Benelli factory rider in 1959. His best year was in 1969 when he finished second to Giacomo Agostini in the 350cc world championship.[1] In 1971, Grassetti won the 250cc Austrian and Belgian Grand Prix races, but inconsistent results relegated him to only seventh place in the championship.[1] He retired in 1974 after suffering serious injuries at the Spa-Francorchamps circuit in Belgium. Grassetti won three Grand Prix races in his career.[1]
