I should really have taken it in and asked them to plug it in and reset ECU or whatever but Covid was still on the go, they were very busy and I just thought it was because I had not been on bikes for 1/4 century. As time went on I got used to it and was much more able to manage things or maybe it got slightly better as time went on but I still had to use the back brake 90% plus of the time and I had covered 2,000 miles so it should have bedded in by then if it was the clutches..
When I got the 2022 I saw what it should really have been like, nice smooth take off as if the clutch was being eased out as you would a standard bike/car/whatever.
A few other things on the 2021, engine braking never worked correctly, mostly it was like I was pulling on the brake quite hard, changing between the EB settings had no noticeable effect. I learned to slow gently by rolling off the throttle and sometimes that would make the EB work like I expected but even then it seemed to have a mind of its own and 99% of the time it was abrupt.
Because of the EB that made coming off the cruise control a pain as it felt like you were braking hard, I found the only way to mitigate that was to open the throttle to where it was just acting and then tapping the gear shift paddle (or brake) , that cut the cruise control and throttle was where it should be for the revs I was doing so no jolt forward.
The different power settings didn't seem to have much effect either, certainly nothing like on my 2022 where I can tell which mode I am in, just by the feel even if I have Waze on the main screen and thus can't see the mode info.
I fitted throttle spacers to take the initial free play out of the throttle and that made a massive difference to the behaviour and absolutely transformed my experience but it was still not as it should have been as the 2022 has shown me.
