its really off a RC51, but it fits and is on my bike. should fit basically any modern honda. f3, f4, rr, 919, 599 all of them.

mounting screws are missing but i bought some gold flathead screws and thats what was holding it on my bike. works great. off the bike and ready to go.

This is a $120+ gas cap w/ missing screws, thats it, works great.

Asking $80
