it all comes down to personal preference, jap bikes are cheap initially but most chop parts have to be made from scratch. they make nice looking bikes but most of them still have that high pitched wine (no offense to anyone with a jap bike) that i don't like. british bikes have a nice sound an lots of torque but on the triumphs you have to be careful with the dreaded sludge trap and they don't have as big of a motor as the HD's but they are lighter. HD's are everywhere so you won't have a problem finding one or parts for it, it just comes down to finding the right one that fits your taste and your vision but you'll pay extra for the HD brand parts(but that's easy to avoid) so choose wisely and don't forget to start a build thread when you get it
