That must be one shiny bike!!
Regular cleaning and occasional polishing is all you need to keep that chrome looking perfect. Adam's Green Wheel cleaner with the Boar's hair brush is your safest way to clean it. Dry thoroughly and use Detail Spray with a single or double soft microfiber to keep that "mirror" look to the chrome. Use Metal #1 and follow with Metal #2 to bring back a better than new look to it once it starts to loose its original luster. With proper maintenance you will not have to polish much at all!
Chrome rusts very slow compared to many metals. It takes moisture and carbon dioxide to combine with that chrome to start the rust process. So the biggest step you can take to minimize chance of rust is to keep it dry.
You can wax it but it will be very tedious and I personally find it is not worth the extra time.
I hope this helps and post some pics:)
