What does motorcycle clock-in mean?

[OAubrey]

Motorcycle clock-in is a specialized device used to lock motorcycles. The concept of an overrunning clutch: An overrunning clutch, abbreviated not as a clutch (it has no abbreviation), manages electric starting, while the clutch handles driving, transmitting the torque generated by the crankshaft. If the overrunning clutch is faulty, it will produce noise during startup and exhibit symptoms similar to rebound. How to open the seat of a ladies' motorcycle: To open the seat of a scooter (ladies' motorcycle), first check if there is a keyhole on the left plastic guard of the seat. If there is a dedicated keyhole, insert the key and turn it slightly to open the seat. If there is no keyhole there, it is usually integrated into the handlebar lock. Insert the key into the handlebar lock without pressing it down (just insert it fully), then turn it directly to the left (counterclockwise, with some resistance) to open the seat.
