GIVI Locks for motorcycle cases
If your relationship with your passenger gets a bit strained, you can easily change the locks on your bike cases.
But seriously, here you can find security locks for cases. Because you've lost all your keys, because bought a second hand motorcycle and want to make sure you're the only one with access to the cases, or because your relationship with your passenger is more than a bit strained.
For each lock it is clearly indicated for which cases it is suited.
