I don’t have any direct info on how it works, but I would have assumed it could be done completely offline with some sort of accelerometers. But I am a Lay Person so… ¯\_(ツ)_/¯
Accelerometers don’t work that great with motorcycles; when you go into a hard turn, the accelerometer still thinks that you’re straight up, due to centripedal force. You’d actually need gyroscopes. (…Which is why adaptive headlights for motorcycles end up being so expensive, and why only BMW specs them, and only on one or two touring models.)
