Made up toolkit sets appear on fleabay now and then.
Someone in the UK even specialises in them, but him having one for a specific year and model may be a little hopeful.
As slick says, you can put together a basic toolkit using whitworth/BS type spanners, a screwdriver and greasegun and tire irons, plug spanner, wheel wrench, feeler gauges etc. It soon gets big and bulky if you plan for everything etc. Some folks say to leave it in the workshop, and just carry a credit card (!).
More than a few folks have commented too that tools soon wear through those canvas type toolrolls, unless something fairly tough is wrapped around the tools. You also need to make sure the toolkit can't jump out of its carrying space and disappear off the side of the road. Although the dommie with its underseat tool tray may be immune from this. I bought a cheapy toolkit in a roll for an Enfield, and it came with whitworth spanners and the basics, and was quite inexpensive. Quality was usable, but you won't win a concours display with them.
