For 1988 Yamaha rebuilt the 0W98 with a different V-angle (60>70 degrees) in order to create more space for the larger reed-valve system. The rear swing arm was a-symmetrical because of the new exhaustsystem. Eddy Lawson won 7 races and his third World Championship and with also Kevin Magee and Wayne Rainey as GP winners Yamaha clinched the Manufacturers title once more. During one race Eddy won with carbon discs for the first time.
