Yes, definitely I'd do it again.

I appreciate you thinking to ask this wonderful question.

The only difference this time, I'd go for a bigger and better motorcycle. I learned to drive in Vietnam before I made my motorcycle driver's licence back in Germany. After ten years of experience on two wheels and a few real badass motorcycles, I'd love to have another experience there.
Though, travelling by a van, a little camper van, should be comfy and luxurious. Or on a bicycle. Not minding the time. No pressure. No competition, only the joy of the environment's and culture's difference.
