Cross model Compatibility

Honda street bikes in the 80s' seemed to share a common fork stabilizer/bridge across many platforms and years. Many even seem to share the "skirt" that goes down to the wheel fender. Stainless-steel reinforcement plates sold on e-bay match far more model than they list.

Issues

The fork bridge on the 1985 CB650SC is part number 53240-MB1-050 called "BRACE.,FR.FORK", and this is a very thinly made piece of chromed aluminum with a rectangle of material removed on the sides where the fork tubes hide it, and two slots in the rear that may start a crack, and then will continue to crack to the point of failure.

Analysis of issues

The catalog also lists a "STAB,FR FORK" Part number: 53240-MB1-030 and "STABI.,FR.FORK" Part number: 53240-MB1-040. As the names characterize, -050 is only a "Bridge" while -030 and -040 are "Stabilizers". Looking at the 1983 CB1000, which also lists all three of the parts above in its catalog, there are -020 "STABILIZER FR FOK" which has side/tube cutouts. -010 "STABI FR FORK", which has slots cut rather than the entire square cutout on the side/fork area. Finally it lists -000, perhaps this is the solid bridge?
