Yea, the roads are slick as shit here, if it rains they are like Ice. You don NOT want to get stuck out in the rain. Most of the Okinawan/Japanese don't like sport bikes too much as they are all in to the naked bike thing, but the population of sport bikes is definitely on the rise.
Remixx02, be sure to send your bike in your household goods, but you will have to pay about 2k ish to run it threw gas testing before they will let your register it. Or you can sell it and get a 07 R6 for about 10K that has been imported from Canada. That is the out the door price with all of the importation crap taken care of. You will have to do some importation stuff to bring it back to the USA with you when your tour ends.
Rainking32, I'm thinking of going for a little run up north here in a few, if your not doing anything and wanna shoot up that way shoot me a PM..
