Dave,
At the local dealer in NJ, the 500 Bullet sells for the same price as the 650 Twins. The sales manager says the main market for the Bullets are ex-Pat Indians. Still a status symbol. They buy the bikes, go to the Temple and family gatherings and everyone oohs and aahs.
I asked one of my customers (ex-Pat Indian) who was lusting after a Bullet if he'd ever gone 80 MPH for an hour in the old county. He just laughed. Said he go to 50 for a few seconds.
Explained that a non-counterbalanced single on a major US highway is a truly painful experience. I think he gets it.
Funny thing, he rode his brother's Sportster the other day and thought it was an absolute rocket ship

I wish RE had made the singles counterbalanced and E-Start when they did the Continental GT. Very pretty bike, just gutless and tons of vibration. I believe they discontinued it.
I think the company will see major sales in the US if the new models hod up.
S&S already has performance parts for the twins. Pipes, cam, airbox stuff.
Could be the new tinkerer's special.
