I have!
Took a HP model out for a couple of hrs while mine was being serviced & having a new tyre fitted.
Wow! It really is like a different bike, everything seemed so slick & positive, if not rather subdued & quiet, a bit characterless! Think I actually prefer the farting sound mine makes on a downshift but the annoying valvetrain rattle is now a welcome thing of the past.
Boy! does it go! Pulling past a line of cars in 4th gear, the pick up was noticeably improved over my 2016 GS no hint of any cam lobe change over hesitancy. Slow speed riding is noticeably smoother, less chuggy! too.
1st time I’ve ridden one with the LCD screen & was very impressed with how it looks & how easy it is to read. Having not dived into the instruction manual or had much pre tuition into how to use its functions, I did struggle a bit with how to acknowledge commands & found it very frustrating to not be able to reset the trip counter by just holding a button. (Later discovered how to do it via a menu page & that the “auto reset” function had been disabled by a previous rider.)
Also new to me was the hill hold assist, which I was informed had two settings? But didn’t discover how to use it other than just pulling hard on the front brake lever.
Might consider a retro-fit if the price is right?
Stuff I didn’t like, the standard GS screen, which I replaced on mine with a tall Puig far quieter, much less turbulent & allows riding with the chinpiece raised
The colour schemes, which I think are terrible, the only one I’d entertain is the metallic blue one.
Would I change for the sake of it? Probably not.
Next bike, probably (hope they bring back racing red by then!)
