I've been saying this all along
Beemers have it right and so does Harley. You don't even have to adjust valves on Harleys and Buells, except for the V-Rod. Now with fuel injection you don't even have to sync carbs anymore. I understand that Ducatis have desmotronic valve trains that are pretty difficult to adjust (just what I've read). If you ask me, the less you have to maintain the better off you are. Ok, a crotch rocket is way faster but you know what? Who cares. When you factor in all the speeding tickets and higher insurance premiums and the high cost of replacing plastic body panels and skin grafts, and relearning the alphabet, you are way ahead on a Harley, or Beemer.
