What Motorbike should I get?

I am going to get a new motorcycle. The question is, what should I get?
I want to do long rides, and I do mean long ..... around New Zealand, around Australia type long.
When looking at various motorcycles, I am taking into account the following "must haves"

• Must be an upright riding position
• Must have a comfortable seat
• must be capable of carrying lots of luggage
• Must have nationwide coverage for service and support, or at least be a common brand that it is likely there will be people around who know how everything works.
• Must have good fuel economy and a large (20l+) tank.

My 1st choice at the moment is a Suzuki DL650 Wee-Strom. Seems to fit my requirements nicely and isn't too expensive.
Keen to hear what anyone else thinks. So drop me a comment below with what you would buy to do the kind of trips I am planning.
