I just got my B-King a week and a half ago(already have almost 1,200 miles on it) and I've got to say it's probably the best deal I've ever made on a bike.
As far as spare parts are concerned, '09's and '10's are being sold in Europe(and Canada, I believe), so spare parts shouldn't be a problem. There are quite a few aftermarket items available from European suppliers as well.
To think that I was able to purchase a bike with perhaps the best engine in motorcycling, with an "all day" riding position and a "unique" look for less than the price of a "cookie cutter" 600cc sportbike is just amazing.
I'm absolutely thrilled with my purchase. If you're thinking about getting one......do it now before(as was mentioned previously) supplies dry up, especially as people find out how good this bike really is.
