ELF Honda

Between 1981 and 1983, Honda’s outlandish ELF prototypes competed in the World Endurance Championships, generating a slew of patents for Honda—including one for a single-sided rear swingarm. Fast but unreliable, the machines were created by Renault designer Andre de Cortanze, who was a keen endurance rider as well as an accomplished automobile designer. Known as the “ELFe”, the bikes raced at the Bol d’Or and Le Mans 24 Hours; this particular machine was rebuilt in 2008 by the French restoration experts Kerlo Classic, in collaboration with former racer Hubert Rigal.
