it's subjective and also depends on what you are used to.
For alot of people, it will likely be their first QS experience, but you take the KTM 1290 out for example and you will soon realise thats one smooth quickshifter in comparison
It is subjective, but I still don't accept that mine's working correctly when it completely mis-shifts on occasion and is rough in the first few gears. Lol.
I just don't understand it because they've done a good job on the S1000RR and XR and then complete trash in comparison for the GS. I'm sure that the characteristics of the engine could play a part, but if everyone is saying different things then it sounds more like a calibration issue or something? Don't know, and I'll stop moaning about mine now. Haha.
