Emil Bollhalder

Emil Bollhalder is a retired Swiss sidecarcross rider who won the Sidecarcross World Championship twice, in 1982 and 1983, with Karl Büsser as his passenger. He had earlier taken the European Championship in 1979, the last running of the title that preceded the World Championship, riding with Roland Bollhalder in the sidecar. He made his national and international debut in 1974, finished as runner-up in the Swiss championship and came tenth in the FIM Cup, the predecessor of the European Championship, with Ruedi Kasper as passenger. His first season in the new World Championship, with Ruedi Manser, brought only two events and 24th place overall. From 1981 he rode with Büsser for most of the season, and the pair went on to win both world titles. He also won the Swiss national sidecarcross championship in 1982 and 1983.
