Tips for long distance comfort

[dickturpin]

So, yesterday I rode back from Campbeltown on the Mull of Kintyre to my home on the Yorkshire coast. About 350 miles over 11 hours as I took the scenic route.
Much as I love my fazer I do have an issue with comfort on a long haul...admitidly it would probably be he same on any bike after that duration.
I have tried putting different foam in the seat and that has helped.
So what is the secret to comfort on long trips? Share your secrets here.....
