Linkage Pivot Service
On the 1982 CR125, the rear suspension linkage pivots were a new addition to the CR line. Inspect all pivot bolts and bearings for wear or seizing during each seasonal service. Clean and re-grease the linkage pivot bearings annually, and torque all pivot hardware to spec. Worn or seized linkage pivots significantly degrade rear suspension performance—replacement bearings for this vintage model are available through specialty suppliers if originals are beyond service life.
