The Origin
BOB SMITH &
ATTIC RAT
PERFORMANCE WORKS
"Go Like Hell wasn't just a name. It was a promise — that your Valkyrie would perform like nothing else on the road."
From his shop in Tulsa, Oklahoma, Bob Smith engineered and installed the GLH performance package on Honda Valkyrie motorcycles from 1997 to 2003. Between 100 and 120 bikes were ever modified — making every GLH Valkyrie a rare piece of American motorcycle history.
The original six builds were slightly different from later production packages, representing the earliest evolution of the GLH specification. This registry exists to document, verify, and preserve the complete history of every bike Bob touched.
