unless your bike in indonesia is really non stock, and has been set up in a very specific way for your needs, i'd sell the bike in indo, and buy one here in NZ, it is a small market, but there are plenty of good bikes to be had.

The money saved on shipping can be used to stay on the road longer

Have a look on the website Trade Me.

thanks for all the replies and comments.
@fern:
i'm goin to NZ first and then head over to indonesia. i agree with you there is a lot more good bikes on the market in NZ. thats why i wanted to take a bike from NZ to Indo because the market for dirt bikes in indonesia is rather small.
but i think the best option would be to sell the bike when i leave NZ and get a new one in indonesia

last year I had a quote from Mainfreight, from Auckland to UK, sea freight, $600 (not including crating, and excluding destination port clearance costs)
