I got 18,000 miles out of a chain and sprockets in the US, although I have to say they were totally shot by then - adjusting chain every couple of days!

You can check the chain wear by lifting it off the rear sprocket (it shouldn't lift more than a couple of mm). To be honest, if you've been using a scott-oiler, it should still be fine after only 9.5K, unless you've been riding in a lot of dusty or wet conditions perhaps?

I don't imagine the [tread pattern of] Tourances would cause significant vibration, although as Tony660x suggests, you might want to check the wheel balance.

I'd go through things one by one - check tyre pressures, wheel bearings, chain wear/slack, cush drive rubbers - those would be the 'physical' things...

However, if it feels more like it coming from the engine itself, then possibly something is up with the fuel mixture and/or TPS (throttle position sensor), but I'm not techy in that respect - Kev can probably offer more precise advice there...
