This part was never sold by Honda as a separate item, originally this part would have come supplied with the air filter element. This reproduction part has been made as close as possible to the original, one side is smooth which should be glued to the air filter element and the other side has raised ridges to help form a seal with the metal plate on the CZ100 frame.  
  • Made in the United Kingdom. 
  • Made from a hydrocarbon resistant material.
We sell a genuine Honda air filter element and a reproduction air filter element, both are compatible with this rubber seal.

We originally had this part produced for the Honda CZ100 but later found out it will also work on the Honda C100.
