Think I want a touring bike?

I really want to do London to Delhi. didn't make it all the way on the last try as was thwarted by the lack of Iranian visa. might go for it again next summer if funds allow.

The Pakistan part of that trip would scare the shit out of me. All the travel logs I've read of people who go through Pakistan seem to say it's a big hassle with security and having to have military escorts in some places.
