Hi,
You mean the storage compartment(s) and using a combination padlock instead of a key?
Obviously, it's more than feasible to fit lock type x or lock type y, so long as you are the manufacturer of the storage box/motorbike.
Why would you ask if you already know that suitcases and briefcases have them? - The proof of concept is there in both cases.
It would be far more interesting to use RFID or facial or voice recognition some other kind of electronic system. A battery of kinetic energy-harvesting devices could be used to power a reciever in the box/briefcase which could power a nanobot-solenoid which is activated and deactivated by a key fob/a hand gesture/a special utterance/thumbprint and retina recognition scanner.
Thought control of electronic devices would be the next advance I'd like to see in the near future.
