Siegfried Müller

Siegfried Müller is a retired German sidecarcross passenger who, riding with driver Reinhard Böhler, became the first world champion of the sport when the series was renamed the FIM World Championship in 1980. He also won the German national sidecarcross championship in the same year. Müller made his international debut in 1974 in the FIM Cup, a forerunner of the world championship, finishing sixth overall with driver Eugen Siegle, and then placed fifth in the European championship in 1976. After two more seasons with Siegle he joined Böhler for 1979. Together they took the 1980 title with an 88 point gap to the second placed team, and they remain the only German crew to have won it. Müller raced with Böhler again in 1981 before retiring from international competition.
