I guess the biggest problem is in production numbers. It cost a lot more to produce a bike with limited production. They won't be making them in numbers anywhere near Triumph much less Harley.
When they resurrected Chris Craft Boats, they were very pricey compared to other boats. It becomes a matter of making a profit or not. Look what OCC's production bikes cost. I'm sure they will sell all they can make initially. People are paying that for Screaming Eagle Harleys and they sell all they make.
