With just a bit more engineering, the Morgan designers could have left the Iconic V-Twin in place, but gutted of all internals. That would have made for a better front/rear weight distribution, and the motive force could have come from an electric motor in the back, with batteries in the area where the current oil reservoir exists. The bevel box would be history.
Completely feasible with today's electronic technology would have been a "noise generator" that would mimic the incomparable JAP or Matchless sound, properly matched to the throttle position.
Then the machine would have satisfied the purists, the ecology-minded, the techno-freaks, and the European authorities on noise, pollution, etc.
