I installed Galfer Kevlar front brake pads on my 07' 250. Love them. Had to re-adjust my "shorty" lever. The Kevlar pads are very kind to the disc and in fact are "polishing out" the damage the O.E.M. semi-metallic pads have done to my disc. They have great feel and terrific stopping power. I'm even going to dump my nearly new O.E.M. rear pads for Kevlar. I bought the front pads in February and then Motosport.com came out with an offer to buy the fronts and the rears were free. Story of my life.
Try em', I think you'll like em'.
