Frequently Asked Questions
What does Honda center-stand spring plate 50523-300-010 do?
The plate provides the attachment point for the center-stand return spring on the compatible SOHC CB500, CB550 and CB750 models and replaces Honda OEM 50523-300-010.
How many center-stand spring plates are included and required?
One spring plate is included, and one is used in the center-stand spring linkage on one compatible motorcycle. The return spring is not included.
What should be inspected if the center stand will not retract?
Check the spring, both hook points, stand pivots, frame mounts and stop for wear, binding or bending. Support the motorcycle securely and use a controlled spring-installation method because a stretched center-stand spring stores significant energy.
