I always thought they chould call themselves Orange County Customs, since they do not build "choppers". In their defense, after 20 years of building custom bikes, a lot of the prefab parts they use are of their own design. Other custom builders (West Coast and Paul Yaffe come to mind) do the same thing. Nothing wrong with that really. If you spent 15 hours perfecting the perfect zero g roll, wouldn't you use it on your next coaster too?
But, a custom bike is a custom bike, not a chopper. I will say, that while I think the OCC bikes are not the greatest, the show itself is entertaining, which is probably the big reason they are on tv rather than the quality of their work.
