1986 YZR250 (0W82)
(1986 / Racing Machine)
This was the first pure 250cc class factory machine since the 1973 YZR250 (0W17). Mounted in an aluminum Deltabox frame, the engine was an evolved version of the 2-axis crankshaft, 60° V-twin built as a prototype in the development process of the YZR500 (0W81). The simultaneous firing configuration adopted to reduce vibration resulted in superbly dynamic performance and agile handling that helped Carlos Lavado win his second World Championship in 1986. In the final round of the same year, Tadahiko Taira chalked up his first GP win at the San Marino GP.
