A monster machine refined from the TZ750
This was a factory machine designed for competition in the World F750 and Daytona 200. The engine of the 1975 0W29 was increased to a displacement to 748cc and the chassis featured Monocross suspension and a 1-up, 3-down muffler design. The 0W31 introduced in 1976 was developed with the 0W29 engine and the YZR500 (0W23) chassis as its base units.The exterior styling was based on the YZR500, which distinguished it clearly from the production model TZ750. After that, it continued to evolve until the end of the F750 World Championship as a competition in 1979, and in its final version with six scavenging cylinders, it achieved a max. power output of 160PS and a top speed of 300km/h. The 1977 model TZ750 (domestic release in 1978) was design with feedback from the first 0W31 specs.
