1987 YZR500 (0W86)
(1987 / Racing Machine)
This GP500 factory machine was developed with measures to comply with the new regulation adopted in 1987. The length of the tail pipe was extended for noise reduction (110db→105db). Furthermore, improvements in a number of areas such as a revised mounting position for the engine, increased radiator capacity and expanded air duct for improved cooling performance helped boost power output. Eddie Lawson took 5 wins with Randy Mamola notching 3 wins to give Yamaha its 4th Manufacturer title.
