I dont mind shaft drive, my old R100RS had it. never gave any bother.

I read a report in one of the magazines last year that most of the noise generated by a bike is from the chain drive system, and now that we have whisper quiet emissions from our silencers ( When standard ) The noise generated by the chain drive is an area where manufactures can cut down noise to meet the standard. I think the test in the mag was a standard Honda Fireblade was driven past as required under the test with the engine on and then with the engine off. There was virtualy no difference in the noise recorded. It is an area where manufactures can cut noise hence thicker chain caseings, rubber inserts in sprockets.
