I also have an R and yep,you've described it better than i could.I once in a while drag race mine and the clutch action is callenging to say the least,i've now junked the slipper and put one in from a 748 S .The clutch plate wear is also interesting ( 3.000 miles ),which should also improve.The horrible (fluffy)low throttle and R.P.M responce is kind of normal too.Dont forget that they are basically ever so slightly detuned race bikes.If you fit a F.I.M chip instead of the usual,the whole fueling can be adjusted by a "plug in and play"on the rolling road.They really are pleasure and pain in one package but put 50mm Termis on and the noise is ,well frankly expensive,boom and bite at the same time.
