Yes, it is possible to replace the headlight and mask of a new CB Hornet 160R with those from an old CB Hornet 160R, as long as they are compatible and designed to fit the same model. However, please note that modifications like this may require some additional work and adjustments to ensure proper fitment and functionality.
Before proceeding with the replacement, it is recommended to consult with a professional mechanic or authorized service center to ensure compatibility and receive guidance on the necessary steps involved in the modification.
