So I received my V mini tank bag today, boy is this bag tiny, exactly what I wanted. It holds my wallet, keys, EZ pass, garage door opener, Eye drops, etc. I attached an Otter Box phone cradle to the clear plastic, phone wouldn't fit inside sleeve. Here's the crazy thing, I have a 2021 goldwing tour DCT with a plastic tank. I velcroed strong magnets on the inside cubby/ gas cap covers, works great. I'd score this bag a 5 out of 5, as I got exactly what I wanted
I got the mini for the same reasons you stated. Keys, wallet, phone, phone charger, garage door opener, insurance and registration cards… all fit in a small bag that’s easy to put in a helmet (that happens to fit in a pannier on my Versys 1000) if I need it secured.
