I bought a K1300GT today. I'll pick it up in two weeks. Wahay! That is all.
FOAF has one, and was with a group of four who stopped in en-route from a 6-day trip to Austria. Apparently the K, with 170bhp, had at least 50% more, and possibly 100%, than the other bikes, but its rider was so painfully slow he'd make Ginge look like a TT winner.
I would be that slow person. But I'm still going to enjoy it. It's only 160bhp, anyway. 170 would be silly.
