1150GS v 1150GSA v 1200GS

[ricochet]

Okay I've been reading bits and pieces from the forum for the past couple of months having newly discovered the site and thinking its damn good!! My question to hand is this: Other than suspension and a larger tank is there much difference between GS and GSA, and would it be just more cost effective to change the parts on the GS? I've read some good points and not so good points about the new 1200,which could all be placed down to teething problems, [not something I would want to come across in the outback of Oz.] My intention is after a test ride around Australia to then ship to Hong Kong and go on up through into China, Mongolia, and on to Russia and Europe. Since you all know so much more than me about these bikes, any suggestions?? I've plenty of experience racing 650KTM's so a bit of weight isn't too much of a concern..
Look forward to any thoughts
