The demonstrator I tried before I bought mine did not have the transmission clunk, as described, but my bike does. In two trips to my dealer they've replaced the gearbox, then the final drive (excessive play) and driveshaft. It still clunks though not quite as badly. New gearbox has a noticably lighter action though. Not sure what to do next, 'cos it's still nagging me. It's either something else - I can only think of the clutch, or one of the new components has the same feature. Or the demonstrator was a rare exception.
