Gosh, I must be stupid. To my eyes the K 1 was a styling exercise that failed. If you are 6'5" fine. I would take a K1100 over a K1 any day. Better ergonomics for my 5'10" frame. Perfect for my R100RS too.
I don't think anyone paid retail for a K1. About 20 other more desirable and collectible bikes come to mind.
Whatever blows up your skirt.... Hell, some folks collect Vegas.
