that bike is awsome,i believe it is factory racer ?Moultonguy's photostream goes into detail on some racer's,some company back then did do after market racing arms,forks,etc,as far as the rear bracing it would have to be cut and shorted and welded,,YIKES!,i think i'll keep it for longer hauls so i can throw a trunk on there,plus it's good for hauling a 6-pack heres a updated pic
