Pressure Plate Spacer Ring
Whenever replacing the clutch assembly, this part should be changed out too. The clutch carrier (flywheel) of the K1200 is aluminum and so this ring's purpose is to provide a solid base for the diaphragm spring. This is a part that wears and should be replaced for optimal clutch performance.
