Keith Gold courier top box, unsure if originaly built for Honda NC700 or Honda CB500
It's big, it's designed to use the space of a pillion rider.
This one has a metal reinforcement plate so technically it could be fitted on anything with will and effort.
This has been taken apart, repaired with heavy duty hinges and bolted rather than riveted to aid longevity.
And will come with new barrel lock.
It came with a 25mm ply wood fixing plate, a bit old school but if it helps , it's included.
New these things are nearly £500
