Hello - I'm a new member on HU - my first post... hopefully in the right place??

Am at the early stages of planning a rtw trip, starting in Sth Africa, up to Egypt, Middle East, Caucuses, Central Asia, Russia, Mongolia, China (maybe...) and sth east Asia. Currently I have organised the bike, a lot of maps, a year off work, the budget and a lot of enthusiasm

So I'm now working on Insurance and Visas... which brings me here - do I try to organise all the visas and insurance before i leave, or can i do this as i go without too much headache?

Reading these threads it seems possible to do it as i go, but am wondering if people have done this, is it a real pain in the a??

And if i do choose to do it this way, are there things i can do to simplify the process on the road?

I want my route to be fairly flexible so if visas can be done along the way that would be great.

Insurance might be simpler to try and get a policy in place before leaving to avoid more work on the road though. And does anyone in the world offer a comprehensive insurance policy or is it all excess coverage (as per motorcycle express)?

Would like to know if there is a consensus for this among experienced travellers?

Any feedback would be much appreciated!

Thanks Dean.
