I didnt know an older r1200r can be had for $6k. I will have to look into one as a replacement for one of my cruisers. I think the r1200r is the best looking standard bike out there.
As far as big muscle cruisers go, the yamaha raider 1900 is hard to beat. That bike has a great engine, its geared well, and the ergos are very nice as well.
