While in general I would agree that twins and singles have that right look, to me one of the few exceptions is the big Indian inline 4 with the full flowing fenders. I think those fenders are some of the best in all of motorcycling. They make the bike look so flowing just sitting still. And I just like the concept of the inline 4 sitting longitudenal, matches the rest of the bike. It looks purpose built as well, but for a much different purpose than a Bonnie or Commando or Manx.
