Unfortunately my bikes are 4000 kms (2500 miles) away and I won't be with them until late April when I go back to my flying job so no measuring until then. I'll also have to look up the gas cap part number for my 03 ZX-6R. I actually have the stock cap here with me because the bike has a keyless Vortex cap on it now.

I read an owner's review of the Givi setup and he mentioned locking would be nice but its still harder to steal it compared to a magnetic or strap mount bag. He said most people would have no idea how to take the tanklock bag off, unless they were familiar with it.
