I understand the point you make about the bad types of example being ghost, FF bikes, and chopper, but I do not understand the Harley type of bike. For me a Harley bike is considered a touring bike, and if I am not mistaken, the military has very similar models that not only are touring models adapted for military purposes, but also have bikes made by the company. For example:
-Harley Davidson WLA
-Bullet 500
-The 1964 KMZ (Dnepr) K750M
-The Zündapp KS750

They have almost the same build as today's Fat Boy Motorcycle, and maybe even the V-rods.

Can you please be clear on that specification of Harley motorcycle? :/
