Here are some brands and part numbers for the Honda CX500, GL500, CX650 or GL650's radiator cap. It's a recovery-type cap - there's an expansion tank behind the motor that the coolant flows into when it expands and it's retrieved as the bike cools down, and the recovery caps allow this to happen. Turbo owners should look in the next section of the page.
