We managed to cross the border at Na Meo with a european registered KTM 950. At first they wouldnt let us in but we kept waiting and waiting..and more waiting. Finally a higher ranking officer came talking with us. We promised him to exit at the same border and he ordered the customs to let us in. We got the pink temp import document and after three hours we were in vietnam! They asked us 20USD for the temp import document which I guess went straight into their pocket but I didnt want to push my luck so I just payed it. Meanwhile we enjoyed the, very cold, north of vietnam and got out of vietnam yesterday. I'll post a trip report later. Hope some other will be able to cross here too!
