I think this is a 2016 V7 II fuel tank.
- mocked up on a 2018 Milano with a factory Milano in the background.
Looks like everything is the same - except the fuel cap on the 2016 blue tank is different. It requires a ring that mounts to the tank and the cap mounts to that.
This was at Flying Tiger Motorcycles in Maplewood (St, Louis) Missouri. I walked in there, looking for a blue one and you know that they will go that extra mile to get you what you want.
LOL - I walked in to buy a blue V7 III that they had on the showroom floor, but when I got there - there was a nice man outside, fastening his license plate to it.
Oh well.
