I'm currently building a chopper. I purchase my frame at Rolling Thunder. They are the best, and most of my parts at Demon's cycles. It took me over 1 year to get my parts from this company even though I had fully paid ($11,000.00) for my order. DON'T DO BUSINESS WITH DEMON'S CYCLES. THEY ARE A PAIN IN THE ASS. I STILL HAVEN'T GOT THE MSO FOR THE MOTOR NOR THE TRANNY.
