Tony, I purchased a B-King during the summer for $8,900 and think I got a great deal. $7,000 is killer!
Yes, the riding position is more upright, but still somewhat sporty. I've ridden a 460 mile day already and had no soreness or discomfort whatsoever. Most sport touring bikes I've ridden aren't as comfortable, including my '08 Buell Ulysses XT, which gives me some comfort issues after only 300 miles. So, I think the comfort makes the bike an excellent candidate for sport touring and any other type of riding. If you add some luggage, like ZG in the B-King section of this forum(check out his pics), it can become a full blown tourer.
The flat bar also gives you excellent leverage on twisty roads so that even though the wheelbase is 1-1/2" longer than the Busa, it handles extremely well. As others have noted, wind management is outstanding for a naked bike, in fact the best of any naked bike I've owned and I've owned far too many.
For me, I love the fact that they're not common.....and obviously won't be in the future. Parts availability shouldn't be a problem, however, as most parts(engine, brakes, etc.) are from other models. The swingarm, dash and plastic bits are unique, but the fact these bikes were/are sold in Europe for 2008, 2009 and 2010 should help.
Frankly, this was a very good bike for the list price, considering its capabilities and quality of components and manufacture. At anything less than 8,000, it's probably one of the best motorcycle bargains ever.
.. How much work is it to change the bars to a busa setup? I cant seem to find pictures of the bking bars/tree setup online.
