The costliest bikes are Trike conversions, which can top out near $40,000, regardless if they started out as Honda Gold Wings or HD's. For two wheelers, HD tops the list for American made bikes. Full dresser Road King is in the 30's. Understand Ducati makes 900cc carbon fibre chassis crotch rocket that tops out at over 220 MPH right off the show room floor. Not sold in this country, but if did, would be in the high 40's - hand built, limited edition, made to order bike.
