The Big Yella Bike is, officially, a 1997 Honda GL1500-C Valkyrie.
Known as a"Standard", since she came without saddlebags or windshield, her flat six engine was advertised as making 100 hp. With a dry weight of 680 lbs. she had the best power-to-weight ratio of any of the big cruisers of the time.
The Valkyrie was dubbed the 1990s' "Cruiser of the Decade".
