"The OG Muffler Bike" -A George Utterback masterpiece




I spoke with Jeff Utterback last year about Bigtube 001 after buying a few other things from him. Very nice guy. He told me that Bigtube was the brainchild of Mr. George Utterback, Jeff's dad, of "G"JS. It was 1983 and this f/f was purpose built for pro-class racing ex. 1983 ESPN event where Jeff utterback was piloting one.


I bought this bike as a f/f in primer. I sandblasted it and is now finished in silky gloss black with custom hand cut decals. 


This particular refresh of Bigtube 001 has been done in a freestyle theme for the 2020 buildoff, as a salute to it's gnarley freestylin "dualsport" past. 


There is a black and white ramp shot of a Bigtube getting air in in the 80's attached. I first built it back up as a race machine for a show (see previous thread).  Big Booty is my pride and joy. I wish everyone could have one.
