I dont know much about riding a bike in Myanmar, but I have spent some time there, and thought that I would just give a bit of what I know about it.

I found it to be one of the richest countries I have ever been to as far as having true, genuine kind hearted people. Seriously the nicest people I have met in the world. It is a very poor country, and as was mentioned earlier, sufferes from a very corrupt government, but the people! So good and kind!

I went to bagan (a must! its like a temple paradise!) Yangon, and Bago. I met people who had not seen a white person before (I did some trekking out around bago and up towards the golden rock)! I would HIGHLY recommend you going there.

One thing as noted earlier, you dont want to give money to the government. Make sure you stay with the people, support locals, not 5 star hotels (even though you can get like the nicest room in the county for something like 75 bucks a night). Most temples and monestaries will let you stay and sleep for free. Even eat!

I found that there was kinda a clear way that you should go and shouldnt go as far as what the government wants. I did some hitch hiking and saw some military brutality, but if you stick to the main roads, you wont see anything like that.

One intresting thing, is it really is where cars go to die. I saw them stiched together with chicken wire and ducktape. Im sure if you have a nice bike, you will be very popular everyhere you go. Bring toys or small gifts for people. It is VERY illegal for you to give them foreign money. Oh and alway get your money exchanged on the black market. the offical exchange rate is like 400 kyat (''Chat'') to a dollar, but if you bring crisp (really, they must be crisp and new) bills (bigger the better exchange rate) you can get around 1300! Also there are no ATMs or good ways to get money out so bring it with you.

Hope that helps! I wish I could go with you. Myanmar is probably one of my most favorite places in the world!
