Before using this site please read the site disclaimer.


This page has specifications for just about everything on the Honda CX500, GL500, CX650, GL650, Turbos and CX400E bikes - with more variants and data to come. Click on a checkbox to show the specs for that model.

Please note - there are almost guaranteed to be some errors in the below figures and this list will get an update once we get some more time with the manuals to double check things.

Also note - currently the table will continue to expand to the right, which breaks the page. Try not to add too many for now until we add some scrolling functionality to the table.
