On his arrival at Bedford's train station, Mutt Williams drove through a cloud of steam generated by the locomotive of a departing train on his motorcycle. Mutt then rode on the platform alongside the train to look for Professor Indiana Jones. Jones left the train, and the pair traveled to Arnie's Diner where Mutt asked for Jones's help to find Mutt's mother Marion Ravenwood and his "uncle" Harold Oxley.
After they were forced by two KGB agents to leave the diner, they proceeded to escape on Mutt's motorcycle. They were then chased by KGB agents across the Marshall College campus until they arrived in the library where the motorcycle fell onto its side and the pair slid under multiple rows of benches before stopping. Thereafter, they drove to Jones' home.
When they flew to Nazca in Peru, Mutt took his motorcycle with him on the airplane. He hid it when he and Jones arrived at the Chauchilla Cemetery, but he was forced to abandon it when they were captured by Soviet agents.
Behind the scenes
As Mutt's motorcycle, a 2006 Harley-Davidson Softail Springer Classic was used. The motorcycle had been modified by bike builder Justin Kell using original Harley accessory parts to make it look fifty years older. Nevertheless, some details such as the twin cam cylinder heads or the the front disc brake made it appearant to Harley-Davidson fans that the motorcycle was a more recent model.
Justin Kell also made the motorcycle better suited for the use in stunt sequences by reducing the weight by about 35 kilogramm and increasing the power by about 30 horsepower.
In total, five motorcycles were used for the movie. In April 2009, two of these motorcycles were exhibited at the Harley-Davidson Museum in Milwaukee. One of them had been used in settings in which it was ridden by Shia LaBeouf and Harrison Ford, the other one had been used for filming stunt sequences.
