I didn't think I explained that concept very well. My Bad!

When I use my spare tank helmet lock, my helmet seems to always be upside down, i.e. if it rained, it would fill up, this is because I don't want the helmet resting against my drive chain and get the helmet greasy.
OK, I think I understand.

My drive chain has a full chain guard, so I don't have a similar problem. For that matter, I can have the helmet (actually either of two helmets) on the lock, with the top facing outwards, and no part of the helmet touches the chain guard. That's with the bike on the center stand.
