Hello MarcGimbel
The tracker may exit sleep mode when the motion sensor is triggered, so even slight vibrations (including external ones) can potentially wake it up and increase power consumption. In some cases, the device may also wake up periodically for service tasks, such as checking connection or status. Otherwise, when the motorcycle is off and no movement is detected, it typically remains in sleep mode.
Please note that this behavior depends on the specific tracker model and its configuration. For precise details, it is best to check with the device manufacturer.
