Steve McQueen’s 1963 Triumph Bonneville Desert Sled race bike.
Winning desert races is what this machine was set up for. It is the mount of actor Steve McQueen, who recently won the novice class in a one-hour desert scrambles. The victory only proved what a close look at his Triumph Bonneville suggests: McQueen takes his motorcycling seriously. It takes some modifications to wing the rough, dusty hare ‘n hounds, scrambles and enduros that are popular in the southwestern desert. McQueen’s machine was prepared in Bud Ekins’ Sherman Oaks, California shop. They started by replacing the stock wheel with a 1956 Triumph hub and 19″ wheel to reduce unsprung weight. The forks were fitted with sidecar springs and the rake increased slightly by altering the frame at the steering crown. The rear frame hoop was bent upward to accommodate a 4.00 x 18 Dunlop sports knobby, and to it were welded brackets for the Bates cross-country seat. The bars are by Flanders, with leather hand guards, and the throttle cables run over the tank, through alloy brackets to the twin 1 1/8″ Amal carburetors.
