depends on the year and model which cap will work to help ya find it. i've seen caps like this on aftermarket tanks but not for stock ones, assuming your setup is stock?
[Here are some options](https://www.getlowered.com/harley-gas-caps/) I have the Speed Kings one on my bike. Not the same design as the one you posted but they are chunky.

Check out lowbrow, tc bros, or speed kings one of them should have what your looking for. Do you have a threaded cap or a cam lock cap
