Last week I ordered a new Vulcan S and I'm currently waiting for delivery. In the meantime I'd like to buy a security lock which I would stash while riding in the compartment on the clutch side of the bike. I'm not able to find the inner dimensions of the compartment so I'm not sure which lock to get. I'd appreciate if someone could tell me the dimensions (with depth), maybe just as a comparison with some every day item. Does someone also use it for this purpose?
