Mutt's motorcycle was the motorcycle used by Mutt Williams in the movie Indiana Jones and the Kingdom of the Crystal Skull. It was an amalgamated Harley-Davidson.
The motorcycle first was seen when Mutt appeared on it at the station to look for Professor Jones. It was then used for the sequence in which Mutt and Jones were chased through the town by KGB agents. When they flew to Nazca in Peru, Mutt took his motorcycle with him in the airplane. He hid it when he and Jones arrived at the Chauchilla Cemetery, but had to leave it back when they were captured by Russian 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.
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.
