During the few of factory tours I've been on, they always said they didn't want to go small on engine size.
They kept saying how their sales were growing year on year and didn't want to venture into the smaller cc bike market - too many other manufacturers are already established there.
There wasn't any money to be made in the smaller bikes.
I hear they have their bike stratergy already mapped out up to 2015/16 but as with everything, things change and if they could get some £££ out of building small cc bikes (or re-badging other bikes) in their far east factories, I bet they would look into it.
There is a massive market in the far east alone.
