Also, if any Aprilia owners (or any motorcycle, but I don’t expect Honda or Yamaha owners to relate) had any weird behaviour with their bike, I’d like to hear your stories.
The weird behaviour that makes me ask: after some driving through the mountains and taking a 5min break, the bike wouldn’t start any more, it wouldn’t even try to start. But after another 5mins of staying at the rest stop, the bike decided to start like normal. I’m thinking it didn’t start at first because the bike was really leaned on its stand, because the ground wasn’t leveled, and when I tried starting it the second time I was holding it upright, but still weird.
Soubds like a very sensitive tilt sensor? You want the bike to stop running if it drops, that's what the sensor is for, it is triggered by lean angle. Try and reproduce to test!
