When I lock my top box, it won't lock the little latch properly, and if I pull hard then I can remove my top box entirely without using a key. Had anyone have a similar problem? Bike & Top box are new, I've ridden about 300km's.
Mines fine, hardly been off the bike in 12 months, very useful box. Make sure locking catch and box lock are unlocked, install box, shut the locking latch with the box shut. When you lock with key all should be secure.
