Although your heart's in the right place, I am sure that the makers of Indian (and Buell) will be surprised to know this.
I think Indian declared bankruptcy again last year. Not sure, though. The point is, American M/cycle manufacturers are not as healthy servicing a niche market as Honda & Kawasaki are.
Hondas have been made here for more than 20 or 30 years - Maryville Ohio. The Accord plant is right beside the motorcycle plant.
