lets get rid of some confusion before we start.
There are a coupla different tires that Michelin makes
Pilot Road 2
Pilot Power 2ct
That being said, i dont think you should have problems pairing any of the tires listed above together, they all have a similar profile... i know my buddy who has a KTM 690SMC just got a set, Road 2 out back, and Power 2ct in the front, and absolutely loves it. I went with Road 2's front and back because the 919 is a little heavier than his KTM.
