I have owned my K1300s for nearly a year now.
It is amazing. It has the power to give the 1000cc sports bikes a scare down the straights and the handling isnt that far behind them either, I have been held up behind more than one blade when the road got twisty.
The bike is comfortable if you fancy doing a bit of touring and will return 57mpg if you stick below 80 on the motorway. Mine came fully loaded with all the toys and I have to say the quickshifter is well worth the money, even for use on the road. Forget about the Jap sports bike. Get one of these and you will wonder why you even looked at anything else.
