Hi Julien, I was just thinking after reading this post and your recent update(s), maybe you might be interested in a trip/ride that a few riders will be doing at the end of the year: PRC -> Laos -> Thailand (Northern Thailand where there is some fantastic riding routes, and way friendlier circumstances than here IMO), and then back again.
Dates are not set in stone as yet, but looking at possibly December. The time expected for the ride is likely no less than 6 weeks, though realistically probably more, as it would take at least a week or ten days to ride from this part of PRC down to CR. Getting a legally plated PRC bike into the aforementioned countries is easy as Prince666 has just done a complete circumnavigation of said routes (crossing borders without issue) over the last 2 months on a YBR125G (legally plated/documented) - which as turns out was pretty ideal for the trip - as a more dual purpose bike was a necessity for approx 30% of the journey based on the routes chosen - of that 30% roughly 10% a road bike would not have gotten through. Many mud sections and landslides encountered along the way.
Different route choices might make taking a more road orientated bike a viable option.
That said though, there are some really great off-road riding sections worth the ride in Northern Thailand, that makes a dual purpose adventure style bike a worthwhile choice.
Another choice is that one can/could fly into Northern Thailand (ChiangMai or ChiangRai) and rent a bike for the duration. I undertook this option this past January & February 2014, flying from Ningbo - CR and renting/riding a CB500X (excellent bike and did very well off road). I'll add a couple of photos from the trip here shortly... just to get ya taste-buds a-flowing
For the upcoming trip, I've purchased a new imported ADV bike suitable for the intended journey.
PM if you're (or anyone else is) interested.
