Agree with previous poster...
Yep, heres another one who believes that this news only regards importing NEW big bikes to Vietnam, and tourists bringing their own ones in thru their land borders, is another matter altogether (read: WONT get in).
Sorry to think this way, but theyre a communist system, and they just dont like the idea of falangs roaming freely around their land. Will only believe it when I see it, that they actually have lifted their ban on foreign bikes. BTW, my own experience is that it doesnt even matter if you have a smaller/bigger than 175cc bike, you still wont get in. The only way is to buy a bike in Vietnam, then go to Laos, Cambodia, etc, then bring it back, but otherwise is a big problem.
