Mit dem Motorrad durch Laos

I have asked many Motorbikedrivers in Vietnam, if it possible to cross the Border from Vietnam to Laos by Motorbike. Nobody didn*t realy know that. Also in the Net was written a lot of maybe, no or sometimes. Just one guy has said, that it is no Problem and he has done it. Thats way i have try it too and i can say, yes it works. The Customs just wonted to see the Bluecard of my bike and my drivier licence. I have paid 32 USD for my visa on Arrival and nothing else.
By the way, i have bought my bike in Hanoi for 220 USD, i paid 100 USD for repaiers and services and i sold it after 9 weeks for 320 USD in Vang Vieng, Laos.
