Even with felt backing the belt still rubs the paintwork with the vibration.

It's purely decorative from Morgan but I've seen custom straps made and fitted which fasten to the lower body and actually function as a restraining strap.

I've considered fitting the strap ends to some discreet smooth chrome hinges then to the other hinge end to the M3W lower body but I haven't found the appropriate fixings to date.

One day I'll achieve it.
