Hi. It's been discussed a few times in the NZ forum. You'll find many of the basics in this thread here: http://advrider.com/forums/showthread.php?t=702718 Costs vary depending on several factors. (explained in the thread above). Whether it's worth it or not is a personal choice. The short answer is if the bike is rare or desireable, has sentimental value to you or you're just busting your nuts to have one, then maybe yes. If you could reasonably buy one here... then probably not. If it's purely a money thing I would say youd have to be able to buy it overseas for $3-5k cheaper than you can here just to break even, let alone make it worth while. If you're doing it to make money then it'll need to $4-6k cheaper to make it viable.
