I know you won't get it in time but probably the best chain lock in the world for a motorcycle is an
Almax.
Always chain your bike to an immovable object and put a piece of fluorescent cord between the lock/chain and the brake or clutch lever (front wheel secured) or the rear grab rail (rear wheel secured - better).
The fluorescent cord has two purposes:
1. To remind you to remove the lock (DAMHIK
) Note you can (will) damage the brake discs as well as the bodywork and yourself, if you ride off without removing it.
2. To quickly show miscreants that the bike is secured and they should try an easier target.
