I have a Sega Hang-On Ride on that is modified and ready for MAME.
I have cut the base, as in the pictures, added casters, and removed all the original boards and monitor.
This is all ready to re-assemble and hook up the MAME install of your choice.
All the Pots Gears Handles etc are included. The brake handle was a little screwy though
