1985 Honda CB450SC Nighthawk · Seat Base B Support Buying guide
The listing names Honda 77205-286-000 and warns that seats can use multiple rubber shapes and positions. It does not give a complete 1985 CB450SC rubber count. Match the B support’s original profile and reference, then count only the corresponding positions needing this piece.
The product guidance expressly notes more than one possible rubber shape and position in a Honda seat. A request for every seat rubber therefore needs a position and reference list first. This individual B piece should be counted only at its matching support points.
The listed model application supports the corresponding original B-profile seat setting. No dimensions or custom-seat interchange are published. Identify the fitted base and its support shape before treating the motorcycle year as proof that this rubber belongs at every contact with the frame.
Its identity is the molded support profile together with Honda 77205-286-000. The listing notes that Honda seats can use several shapes and positions. Check the required reference at each seat location rather than assigning the same B piece to all supports.
One rubber is supplied per purchase, with no CB450SC total given in the listing. Count the matching B support points that need renewal, keeping other profiles separate. That produces an order for the required individual pieces without assuming a complete seat-rubber set.
Identify that base’s support positions and compare the molded shape with 77205-286-000. The listing establishes the original application but publishes no custom-base dimensions or interchange. Confirm the changed support requirement before buying this individual B rubber from the motorcycle year alone.
