Bent Rotor
 

If you put a disc lock on either brake rotor, be sure to remove it before moving the bike -- at all! Trust me on this...

I have seen that a lot after a few beers, good thing you didn't drop your bike.
I HEAR YA! A real good lesson. :D

I have seen a cable that attaches to your throttle & to the disc lock so you don’t forget it. of course you have to use it that way.
1 more tip don’t forget to put down your kick stand especially when a hundred + people are watching you. (Don’t ask me how I know)

Yes, there's a brightly coloured coiled cable that you can get to attach from your disc lock to whatever you want (usually someplace near your handlebar so it's easily noticed). It acts as a reminder to remove the disc lock. :D
