One of the first truly excellent motorcycle racing games, SuperBike Challenge features smooth CGA graphics, multiplayer options, a wide variety of tracks, and intuitive keyboard and joystick controls. The game's split-screen display in two-player mode is one of the best and first of its kind, and the track selection (12 worldwide) is excellent. You can opt for a practice lap before the competition to get a feel for the track, as well as toggle between three difficulty levels.
Although the game has largely been superseded by newer, more graphically appealing titles, it is definitely worth the nostalgic play-through as a game that was once years ahead of its time. Thumbs up!
