Motorbiking in Asia forum

I recently did some dirtbike riding which helped me realised my motorbike skills are not too bad (said in a humble tone).

I like the idea of hiring a bike here and there and do some pleasant one day rides. Maybe to a site, maybe just for the scenery and in a loop when possible.

Any suggestions for Cambodia, Laos and Vietnam would be appreciated as in specific routes from A to B or C and back to A.

2 or 3 day rides would be interesting also.

Riding in the mayhem of HCMC or Hanoi is tempting! Or just going in or out in the early morning.

Also, should I bring my Australian driver's licence with me or one of those International licences or just nothing?
