Name that Game

Remember Road Rash, originally for the Genesis by Electronic arts? Well, it appears I have found it's "father" of sorts. This game, developed by Nintendo in 1985, has most everything that made Road Rash exciting(sans great graphics). You must navigate treacherous courses, winding around every wild turn after another, while shooting and destroying your motor biking enemies. Very simple in concept but it gets hairy quick! What is this game?
