now why not in the front?? makes absolutely no sense seeing that the majority of your braking power comes from the front?!?! (according to MSF site)
another thing to consider when braking to remember to use the front more is which would be easier to changeout when worn?! 
... i'd like to move up to a drilled or slotted front rotor eventually but have always been asked why we only have ONE rotor and not two?? why, i don't know but it hasn't made a difference on the bike... the thought was that TWO allowed for equal pull when braking so less of a tendency to have it pull one way.

EBC makes some aftermarket rotors for the drifter. I'm going to do this myself on the front asap.EBC Brakes MD4125LSLeft Contour Rotor EBC PN MD4125LS; Rear Rotor PN MD4148
