Most common question I get is, what problems does it have?
Teething problems in any new model are pretty common, but in today's day and age, there are a lot less than on the good old days and usually they are insignificant in the scheme of things. That doesn't mean that they don't get a lot of airtime on the internet forums though.
One thing to be aware of is that there have been a few of the 800 motors (GS and other models) that leak oil out the valve cover gasket. In my case, it was the left hand side, barely noticeable at about 7,500 km, more noticeable at 20,000 and by 30,000 km it would leave a fair coating on the engine over time. I asked a few dealers, they all were aware of but didn't consider it a major issue. There were no new gaskets available, and are currently backordered here so they are clearly getting replaced. Not a major issue, you'll notice it if you have it and you can let you dealer know so that he can order the gasket and replace it at your 10,000 km (6,000 mile) service.
