Off topic slightly, but, was on a 3 day ride with some mates and QS was not working sometimes. Checked the switches and all ok. Had a fiddle with the plug in the solenoid unit and no problems for the whole weekend. Maybe a dry connection? This post just  reminded me to remove and spray some contact cleaner on the plug connections. My bike is 2015. Cheers.

While on this topic, I have a 2020 and going up through the gears, shifter is great. It's the first time I have owned or ridden a bike with one so I don't have any previous experience with them. Every once and a while from 1->2 it will end up in neutral and rev out, which is startling. the biggest issue I have is downshifting. I have read on this forum that if you are "on or off the throttle" it works great. I take "off the throttle" to mean, throttle closed. But I find that if I have the throttle closed, it won't shift AND if I have the throttle on but not accelerating, same issue. In this instance, it will shift but it feels like I am just forcing it into gear and certainly doesn't feel smooth. It works fine if I close the throttle completely closed and then give it just the slightest opening. Not enough to actually give any gas to the engine, literally, the smallest movement in the throttle, it works great. that is a bit hard to explain so hopefully that makes sense. It makes me think there is a position sensor that might be a bit off? But again, I don't have any experience to relate.

Hopefully some kind soul will explain it a bit more to me OR possibly have a fix if it is not correct. Thanks all.

Throttle open when shifting up and closed when downshifting.
Also, upshifting at very low rpm's (below 4000 rpms) can be a little jerky, especially first 3 gears, so give it more revs. On my 2020 I found that the worst QS spot  :001: is when shifting from 2nd to 3rd below 4000 rpm's. It almost always gives a very jerky shift. Also, downshifting gives some resistance in the pedal, so give it some push

Good thought actually mate, it would also cop a lot of rain/water/crud when riding in inclement weather so pulling the connector to give a squirt of contact cleaner and squeeze in some dielectric grease every now and then would definitely help. :028:

I have a qs on my track and race bikes so I’m familiar with them. I have a 16’ xr and compared to the track bikes the xr works as good or better. The higher the rpm the smoother it gets. Auto blip works perfect with throttle fully off but the same applies with the rpms. The higher the better. I believe these features clearly are meant for high performance riding. You can use them for casual riding but I wouldn’t expect them to work flawlessly. Riding the bike in a spirited fashion I find the feature to be amazing!

thanks for the replies. I will definitely have the dealer take a look at it. clutch and chain checked and do not need adjustment.

I have this exact same issue. 2021 S1000XR just bought 12 days ago. It's has with 550Km on the clock and I'm completely frustrated with downshifts.
I'm very used to up&down quickshifters and it used to work flawlessly and very quick on my MV Agusta, but I'm having a difficult time with the XR, so started searching and found this page, so I decided to join the forum (I already introduced myself in the "New Members" page) to ask if you were able to find a fix for this? Thank you in advance.

Sadly no. I used my GS-911 to recalibrate the throttle position but that did not solve it. I don't live all that close to a dealer so I haven't been in to have it fixed yet. I'll probably go in the next month or two during my yearly service. I'm glad to see that I am not the only one with the issue. Misery loves company and all that. I know it shouldn't be that was because I have ridden other year XRs as well as the newer RT and it was exactly the way it is supposed to be....which is not like mine. Welcome to the forum Nuno, please keep me posted with how you make out.

Sadly no.
Sorry to hear that! :(
Well, right now, Portugal is again in confinement, at least until February 15th, so I will not get a chance to go to the dealer before that. Anyway, I'll come back to this topic if there are any developments.
Thank you for welcoming me in the forum, all the best, stay safe.

Unfortunately this is not going to help you out. My QS on my 16XR is as smooth as butter both up and down. Maybe a software update will help?

I know, I've tested a 19XR and it was simply perfect! I also had QS Up&Down on other bikes (still have on my K1300R but that's only UP) with no issues at all.
I'm supposed to get feedback from the dealer tomorrow, let's see...
