Fieldline Motorcycle Backpack

Will this fit a basketball inside?
Looking at the specs, it lists depth at 5.9", baskeballs have a 9" in diameter. Anyone knows if a basketball would fit?

The attached product tag only shows placing it on a Sissy Bar / Backrest bar. I guess it would depend on the thickness of your seat and how it’s designed.

We grabbed the photo sample. A basketball fit just fine. It would probably hold 3-4 basketballs actually.

there is no way a motorcycle will fit in that thing.

Think I can talk them into throwing the motorcycle into the deal??
