I am looking for a show which had a man as the star. He was somekind of a superhero who had a robot suit of some kind. I don't remember much else besides that he had the robot suit which he used while rescuing the day and that he rode a motorcycle. Think the suit was black but I could be wrong.

Take a look at the last post in this thread: https://www.askmehelpdesk.com/movies/late-80s-early-90s-tv-show-20395.html . Might be the same TV series you're looking for.
