All Balls Ktm Rear Wheel Spacers

OE spacers typically wear out within a year of hard riding. OE
wheel spacers should be checked and replaced as needed
with every bearings service. Water and dirt act as a grinding
compound between the seal face and the mating surface of the
spacer. Once the grooves are deep enough, the sealing surface
is lost, allowing water and dirt to pass through and contaminate
the bearing.
