1968 Honda CB450K · Rubber Components Buying guide

Keep front tank, rear tank and seat cushions distinct

The front tank cushion is sold individually with two required per motorcycle. The rear rubber states one used per motorcycle but does not explicitly state supplied quantity. Both seat rubber listings supply individual pieces.

Count front and rear tank supports separately

The front cushion listing gives two required and individual supply. The rear cushion instead states one required but leaves the supplied quantity unconfirmed. Compare the actual mounting arrangement, then verify the rear package contents instead of treating the two descriptions as identical quantity instructions.

Check rubber shape when mounting parts have changed

For an altered tank, seat pan or bracket, compare the support position and removed rubber rather than ordering by year alone. The listings give part references but do not provide measurements to validate every modified arrangement. Confirm the shape and dimensions the installed components need.

CB450K buying questions

Are front and rear tank rubbers supplied together?

They are separate products with different references. The front cushion is explicitly sold individually; the rear listing states one used per motorcycle without an explicit package quantity. Confirm the contents of each purchase before planning the mounting repair.

Does one rear rubber required mean one is definitely supplied?

One used per motorcycle describes the application. The rear listing does not explicitly state supplied quantity, so confirm that detail before ordering. Keep it separate from the front cushion listing, which expressly states individual supply.

How do I check the correct rubber for a changed seat pan?

Compare the seat’s actual support points, the removed cushion shape and the relevant reference. The two seat rubber listings are different parts. Confirm the dimensions required by the altered arrangement before relying on the original model application.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
