Last weekend I did a short errand into the city and at some point I started feeling like I had to brake more than usual when approaching traffic lights, with the throttle released.
It seems that the throttle often doesn't reach 0 so the engine braking doesn't always kick in. Also, sometimes when stopped, the power display shows 0.3 or 0.8 kW instead of 0. And I can hear the motor spinning softly then too. It's supposed to be totally silent, at least I remember that it used to be like that.
Does anyone else have experience with an issue like this? I don't know if it's relevant, but when I first noticed this issue, I stopped by the roadside and restarted the bike. Then it came on with a "TWIST THROTTLE TO 0" message and an S65 error. But luckily those errors went away after some restarts.
