I still love the 1190, only thing I really desire from the 1290 is the cruise control.
Unfortunately the demo bikes do not have the QS so I have not tried it, on the 2017 GS I rode I was not impressed, I reckon I can change gear quicker without it and it was a bit clunky and shite at lower speeds, certainly would not pay £500 (or whatever it costs) to find out the KTM one is no better....
...if my local dealer gets a used 1290 in with it fitted I might ask for a quick run up the road and back to try it.
What KTM ought to do with all these electronic unlock thingies is allow the dealer to turn them on for a limited period so punters can try before they buy (or chuck them on the demo bikes)
