possible to cross to Laos on vietnam bikes.
Hey i road north to south in veitnam in 2008 on a minsk. Amazing month of my asian travels. I brought the bike in hanoi from Mr Cuongs but i know you in the south and looking to rent. I ended up selling my bike in Mui Ne beach to an ozzie who runs a par (pogo pogo's) and a burger joint. Its not far from siagon (a few hundred km's) and i know he does up the minsks and sells them on to travellers. Only dissapointment for me was that he tunes the engines and gets rid of that lovely 2stroke thumping thud that the minsk has!
I met two finnish guys who passed with their minsk into Loas and then got into cambodia from southern laos - so i know it is possible! Apparently it very difficult with a vietnamese bike to go into cambodia first. I was going to try but crashed in Mui Ne, hence the sale!
My advice is stay away from the coast highway 1. just a terrible road. Only good part is the Vam trom pass near Hoi Ann. this section it worth it. Stay in land and you will experience the real vietnam away from the tourists. Especially if you do the Northern ho chi minh road like i did. Had people help me for an hour with bike problems and they would not except my money, later that day got to Sapa (beautiful by the way) who wanted 5US just for pointing the direction. Needless to say i didnt pay him!! Get off the tourist trail and you will see just how beautiful Vietnam is.
Me and my suzuki EN125 will be travelling 20'000km through South America - who said life was dull!!!!!
