Yes, I did it in 1994 on a Yam XJ650 two up and camping/B&B. No motorways, plenty of interesting roads.

My advice: don't bother. Do something which does not require a need to 'complete' it to feel you've done it. A FTFW tour would be a lot more fun.

If you want a focus there are lots of treasure hunt type rides available. Do the waypoints on those and enjoy a ride. For us the Jogle became a slog. Even all these years later it isn't a pleasant memory whereas leisurely touring of Scotland later, on an FJ1200, was a real joy.

In fact, I often ponder foci for trips: graves of particular people, castles and churches are my favourite waypoints.
