This registry is specifically for the Honda CB450D.  There is plenty of conjecture about how many of these motorcycles were produced and how many still exist.  By listing your bike in the registry collectors everywhere can have a definitive resource to refer to.  Knowing how many of these motorcycles exist, what condition they are in and where they're located helps maintain their value and the authenticity of the information we all share.

​

To be included in the registry please send the following information via our contact page:

First & Last Name, Frame #, Engine #, City, State.  Quality photos are appreciated to show condition.
