There is nothing so special that we can't make it or get it made for the M3W. After all that has been the situation for decades so why worry about it now? Look at many of the owners clubs, both car and bike, and their spares schemes. Where there is a will there is a way - as my dad always said!
I would bet that a lot of the parts are off the shelf from major manufacturers and not made inhouse by S&S.
