Sorry but I can't understand the logic of either the above posts.
Firstly, "its a totally different bike". No it isn't, I've ridden both and its only a minor difference. Changing from a Yamaha R1 to a GS would be a "totally different bike" but not from one GS to a later model. As I proved last weekend, all different models of GS did the same thing and were all up to the tasks. You've succumbed to the marketing hype if you believe it is a "totally different bike".
Secondly, the price to change argument is illogical. The depreciation of holding on to the 1150 for one more year would be a lot less than the initial depreciation on a new 1200. Changing bikes more frequently when there is nothing wrong with the old bike is just consumerism for the sake of it. My bike is now depreciation proof and costs me virtually nothing apart from basic running costs. If I was mad enough to buy a new model every couple of years it would cost me many thousands.
I'm always amazed that people seem to be so brainwashed by the manufacturers that they need to have the latest product when it is not necessary and costs them more money. I don't have a problem with this new model need but don't pretend it is for technical or financial reasons because neither of these arguments are valid. The only real reason you buy the new bike in most cases is because you want the "latest toy".
But you guys please keep buying the new models as it keeps the likes of me supplied with nice second-hand machines. And no, its not that I can't afford to buy new (I could easily as many know) but rather I choose to make what I've got last.
I bet the 1200 owners all have the very latest mobiles and plasma screen tellies as well?
