I'm replying under John's post for convenience but from what I read in the posts I wonder how much experience some of the posters have of Harley engines ( I'm OK here because I have had four of them plus a couple of Buells plus two Guzzis)
I really can't see why MMC have gone for the Harley lump on any grounds except a quick publicity fix.
It is not an efficient engine and to achieve he "screamin' eagle" output is well -nigh on impossible. Why the heck they haven't gone for a Guzzi engine with appropriate torque characteristics is beyond me. Equally, we've had a couple of posts about the jap engines. I have only one comment- take a look at the power curves and you'll see why they would never suit the three wheeler Morgan spec. If you doubt what I say, try any Megabusa engined car and you'll soon be disabused.
Me, I'm still a Triking fan!"

All joking aside,
I think that the Morgan company are very brave in thinking and then putting into production their 3 wheeler.
It truly looks magnificent and a credit to the designer who finds himself in the 21 century.
Considering that the Vee engine is at the very front, and that legs only take up so much room....
It would be a golden opportunity to install an electric engine and become a "Green 3 wheeler" to boot?
The modern electric engines I presume dont take up much room and could be scaled down to suit the Morgan?
Do they need lots of extra space for ancillaries or extra fittings?
I dont know, but I wonder if they have thought about this avenue of propulsion?
A solar panel moulded to the shape of the rear topside would be unique, even colour coded to the car body.
Brembo brakes as used on racing motor cycles would give the car more appeal to the boy racers in this forum?

Another "Morgan moment of brilliance"
