The 1983 season would be remembered as one of the most dramatic title chases in the history of Grand Prix racing; Honda's Spencer and Yamaha's Kenny Roberts fought back and forth for the points lead with each of them earning six victories. The season culminated at the penultimate round in Sweden when the two riders collided on the last lap. Roberts ran off the track leaving Spencer to sprint to the finish line and victory. Roberts won the last race but Spencer finished second, securing his first world title by two points.
