One more tip on locks: If you're going to use a keyed lock, take an extra key with you on your trip and keep this key with your spare motorcycle key, electrical-taped to somewhere on your frame. Do not keep spare keys in your pockets or jacket, but that's another thread too. If you use a combination lock, whether its electronic like the one I posted above or your standard gym locker model, send an email to yourself with the combination, and save this email to your saved file. Same way you've sent emails to yourself with copies of your important docs attached.
Anything you travel with that has a key or combination, have a backup system. Motorcycle, pannier boxes, locks, whatever.
