A custom bike builder in Borough Park has returned home after winning big at a national motorcycle competition. Steve Iacona won first place at the Ultimate Builder Custom Bike Show in Daytona Beach, Fla. Up against 37 other contestants, his "Challenger" bike scored him a trophy, a new Harley Davidson motor and $4,000 in prize money. Iacona works nights at a local hospital and spends his days building bikes for customers. He says he is planning for the world championships this summer in Sturgis, S.D.
