The youngest son of Cuban revolutionary Che Guevara has opened an agency offering two-wheel tours of the Caribbean island nation on Harley-Davidsons, in a nod to his father’s passion for motorcycles. The Marxist guerrilla’s storied motorbike journey through South America was immortalised in the 2004 film “Motorcycle Diaries,” directed by Brazil’s Walter Salles and starring Mexican actor Gael Garcia Bernal. The trip, spanning from December 1951 to July 1952, took the 23-year-old revolutionary to Argentina, Chile, Colombia, Peru and Venezuela. Now, Che’s son Ernesto Guevara wants to honour his father’s famous ride by giving visitors to Cuba a “unique” trip through the country on Harley-Davidson motorcycles.
