TheYamaha TZ750 is aseries production two-strokerace motorcycle built byYamaha to compete in theFormula 750 class in the 1970s.Motorcyclist called it "the most notorious and successful roadracing motorcycle of the 1970s".[1] Another journal called it the dominant motorcycle of the era, noting its nine consecutiveDaytona 200 wins, starting in 1974.[2]
Another triumph of note was whenJoey Dunlop rode to victory in the 1980Classic TT during the process of which he upped the lap record on theSnaefell Mountain Course to an average speed of 115.22 mph (185.43 km/h).[3] This is also the fastest recorded lap of the Mountain Course by a Yamaha 750cc two-stroke machine.
It was rated by journalistKevin Cameron as one of the five most influential motorcycle designs: its monoshock suspension, high-strength frame and wide tires were necessary to handle the high engine output, and became standard for sportbikes.[4]
