The next 10 years for the Yamaha YZR500 (1981-1990) were quite spectacular.

The factory version of the mighty Yamaha TZ750 were first called Yamaha TZ750R and later Yamaha YZR750.

The factory YZ623 ccm twin cylinder racer developed from the 1969 AS1 based model up to the latest 0W15 twin in 1975.
