I'm sure some of the saavy enthusiasts have heard about this site, but for those who haven't, it's well worth visiting. Sure, some might think it's a little too European, but there is a lot of interesting / valuable information available.

The originator / moderator has invested a tremendous amount of time in this site and the data base of links is one of the best I've ever seen. I'll also say that "Duckman" (the originator) is right on, I requested some information about a specific product from one of his affiliates and he responded within a couple of hours.
Did you check out most of the C.A.D. bikes on the site? I'd say "Duckman" is a master at his craft. I also think it's wild to compare the differences between the European style of customizing and what is popular here (photo gallery). There are some bizarre creations shown there like the V-twin "Rolls-Royce" bike, etc. Not to mention some of the odd makes / models of vintage bikes.
