I have two GS500 frames that I got from Patrick many years ago. The 2002 has a clean title, the '89 is just itself. My wife had a GS, and I had intended to build a companion bike and/or a track bike. Other projects have taken over, and I'm not going to move forward with the GSs.
$450 for the titled bike, $350 for the other one, or you can have both for $700.
If you're close by, I might be able to deliver.
I assume you're in the US?
I have the other bits but no frame.
Yes, Everett, WA. I do have a truck and can help with a local delivery if necessary. If you're further away and need shipping, I can research what that might take.
