I just found this site through the Mini Moto Maniacs website. I have a NS50f, and have never seen another in real life, and I'm psyched to see so many on this site.
I live in Milwaukee and do mini racing on the NS, and I've been through Wildcat Mt. area on this last M2M (Milwaukee's Fuel Cafe to Mineapolis) on my big bike. Great roads. Can't wait to get out there on the NS.
By the way I've started a NS50F website. It's my first time, and it just went up, but take a look!
