So your trip is going to take more than 25 days, since you are going to stop for a few days at 2 different locations? However you present the whole plan as 12k km in 25 days! Oh and I did 17k km last year in 9 months, mainly NOT on highway, freeway, expressway or whatsoever. So I could just say I did 17.000 km in X hours :P

You still didn't answer the question on how you are going to pass the borders with an illegal bike, I'd like to know how?
