I was wondering why the 450 frame until I saw your post on picking it up cheap.

I dropped the frame off at a fabrication shop to be welded up yesterday he said it will probably be this next Friday when he will get to start on it . the welds are going to done kinda like square tube telescoping which is putting smaller square tubing inside of the tubes on it to have perfect alignment and so the welds are strong but that's all I have for right now I will post pictures of the frame once I pick it up it a few days.

I think I'd be asking for my money back and taking it somewhere else to have those welds redone if it was my bike.
