6 months should be no problem at all. 4 major concerns/solutions I would have:
1: Security. Being overseas I would want my baby to have the safest home possible.
2: Stands to keep the tires off the ground, not to mention they're a great investment for a bike anyway
3: Battery tender. You don't have to take it out of the bike (PITA) just hook up the cable leads to the battery and plug her in
4: LEAVE THE FUEL IN! Properly treated, low ethanol fuel is a very small risk for plastic tank warping issues and will help protect the internals of your motor, injectors, and other various metal bits. Aside from moisture, corrosion can be a pretty big enemy of an engine.
I have several bikes. Some that get very little mileage and get stored a lot. I live for Sta-Bil treated gas. I'm using the Sta-Bil Marine Formula now since it kicks ass on ethanol treated gas better than the normal Sta-Bil. I also live for Battery Tenders. Every one of my bikes and even my farm equipment has one hooked up. They have saved me un-told hundreds of dollars in replacement batteries. In all my long term storage bikes (like yours would be) I drain the fuel every 3-6 months and replace it with fresh Sta-Bil treated fuel. And I run them for a little while to get the fresh treated fuel in the system. Not so much a problem with EFI bikes but a real problem with carb'd bikes! Sta-Bil and Battery Tenders have changed my life for the better!
