I love the looks of the F6B but want to be able to put a 55 litre GIVI trunk on the back for extra storage and a backrest for my girlfriend when she comes along.

Is there a way to install a monokey adapter on the OEM rack or will I need to get an aftermarket rack like the one available from Twisted Throttle (Twisted Throttle Steel Rack Toprack For Honda F6B '13-'16) to do this?

Many thanks.
