Hi All, While my buddy and I were tinkering with our bikes yesterday we noticed a movement in the front end of his bike while holding the brake. He had just changed out the front wheel bearings so was sitting on the scoot and holding the brake while pumping the front end a bit. He noticed that there was still some play in it. After looking at it, it was due to the front rotor and a none solid design, the outter hub was shifting a bit with the brake. Mine did the same but not quite as bad. Mine is new vs. his being about a year old. Does anybody know the reason for this 2 piece rotor from Yamaha?
