John I Posted this on the performance forum "I just installed the EBC floating rotor with sintered pads. Bike stops real nice now but rotor did not install easily. Apparently, even though this floating rotor is sold for our bike as MD601LS, the rotor rivets that seperate the floating rotor from the section that bolts to the wheel interfere with the brake caliper bracket. The fix was to grind down the part of the caliper bracket that came into contact with the rivets. Otherwise, the rivets would clip the bracket as they turned possibly shearing off or worse! I would definetly recommend this upgrade, especially with the progressive springs, but don't think the install is for the novice mechanic like me!"
