I've just done 7000 miles on My K60 and found them to be totally brilliant on my GSA 1200 LC (2015), I put them on my Wifes GS 1200 (2016) and she did not even feel the difference or know I had swaped her tyres. We both off road and green lane and they are good in anything other than MUD and SAND (or snow).
As the previous responses, in the wet I ride and expect a little bit of twitching from the rear, but the front has always been stable and I ride aggressively on road. They can get a bit light and start to osolate at 110 mph, but crusie all day at 70-100 with no isues ... just some tyre noise.
recommend buying decent ear plugs as it saves your hearing anyway
I would say they are nearly as good as Pilot 3's / 4's in the dry, yet you can do off roading and green laning
