EDDIE LAWSON’S 1989 NSR500

When Eddie Lawson left Yamaha after six years and three 500 GP titles to join the Rothmans Honda team for the 1989 season, many people felt it was a mistake. He exchanged the sweet-handling YZR500 he’d won the 1988 title on for the ferocious NSR500 Wayne Gardner had battled with for so long.

Initially, Lawson tried to get crew chief Erv Kanemoto to change the Honda to suit his riding style, then they changed tack and tried to make the NSR stiffer and more predictable.

The previously smooth-riding Lawson looked more out of shape than ever in his career, but thanks to his incredible talent and one very fast powerplant, he won the title for a second successive year against all the odds.
