I changed tires (to normal sizes) and changed final ratio (front and rear sprockets) to 14/43 (I know maybe it is too much, but it is a test only, hovewer i like it ...) But i have a problem: i tried lot of times to "Tire calibration" (from dashboard menu) but the result is always "Failed". (No error message, all other functions ((ABS, DTC...)) looks like working, so i think the sensors ok...). The tire calibration starting normally, "Ready", after "In progress" - but the result is always "Failed" (i always did it in 2. gear and stable 50 km/h of course. Earlier i went 15/43 final ratio without this "calibration failed" problem.) Does anyone have an idea or experience what could be wrong? Thanks a lot!
If you go back to 15/43 and the issue disappears then you’ve solved the problem. You may well have exceeded the available working parameters that the bike can calibrate.
Was the speed on your dash or on your satnav? If you changed the sprocket ratio the speedo may be out a little.
Changed to 14/40 and it calibrated fine. As Shoboshi says, looks like you maybe out off acceptable range of adjustment if switching towards an OEM ratio solves it.
I often have this faff on my Panigale V4S (track only) after a tyre change. Almost always end up sacking it off after 10 seconds or so and just gunning it!! That’ll learn the pesky tyre calibration!!
had a little explore despite "available parameters exceeded" does sound like the most likely answer. A word with technical via a dealer ought to confirm. I know link below is not for your bike, and probably a red herring:- https://static.nhtsa.gov/odi/tsbs/2019/MC-10168791-0001.pdf
Maybe your shifter has died , mine did when I changed the sprocket size.( though not because of it I don’t think) The tyre calibration process didn’t fix it Fitting a new one did
Thanks to all for ideas and help. I went back to 15/43 and "tire calibration" and quick shifter working properly again. So i can confirm the 14/43 is out of tire calibration range.
