From the back of the box:
You're sitting on 750 cc's of screaming machine, chrome and pistons ready for the course. It's you and your cycle against the road, the curves, the other motorcycles and the clock. Hot rubber on hot streets as you scream to victory.
Racing was never so fast and furious.
It takes split second timing. You must know when to cut, when to speed up, when to brake. Hesitate, and there's no way you'll win. Act rashly, and you crash.
You race through progressively harder courses. Finish successfully an you get to try the next one. But don't push your machine too far. Keep your eye on the instruments. Push it to the limit and you win. Push it over and you crash.
