1985 Honda CB450SC Nighthawk Sidecover Damper Types and Individual Supply

Two individually sold damper profiles support sidecover mounting on the 1985 Honda CB450SC Nighthawk. Damper A identifies 17247-303-000 and Damper B identifies 83551-300-000. Inspect the rubber type at each cover location before counting a replacement order, since the listings publish no CB450SC per-side total.

1985 Honda CB450SC Nighthawk · Cover Mount Rubber Profiles Buying guide

Record the rubber type at each cover mounting point

Each product supplies one damper. The application tables describe different A and B totals for other Honda models, but those totals do not establish the 1985 CB450SC arrangement. Keep a location-by-location record for the covers actually fitted, especially if replacement covers were used.

Use the original profile to distinguish the two choices

The damper reference and shape belong together. Other profiles can be used at remaining cover mounting points, as Damper A’s listing explains. Ordering repeated pieces of one type without checking those points can therefore leave the fitted cover’s actual requirements unresolved.

Keep model-specific quantity tables within their stated applications

The descriptions enumerate various CB750, CB550 and other model arrangements. The CB450SC is listed without a corresponding per-side count. Use those tables to understand why quantities vary, then obtain the actual cover arrangement before deciding how many individual A and B dampers to buy.

Common questions

How do I distinguish the two damper choices at a missing cover mount?

Identify the required profile and Honda reference at that location. Damper A is 17247-303-000 and Damper B is 83551-300-000; each is an individual purchase. Cover mounts can use mixed profiles, so a similar rubber appearance alone is insufficient.

Can the per-side counts listed for another Honda determine my order?

The published tables describe those named models, while the CB450SC entry gives no per-side total. Count the matching A and B locations on the fitted covers or confirm their parts diagram. Each damper is sold separately, without an established complete-cover quantity here.

What changes when the motorcycle has replacement sidecovers?

Confirm the mounting-point profiles required by the covers actually installed, using 17247-303-000 or 83551-300-000 only where they match. The listing’s model coverage does not describe an unidentified replacement cover arrangement. Resolve its locations before ordering individual dampers by the frame year.
