The TX750 is a two-cylinder standard motorcycle built by Yamaha.The bike was released in 1972. Significant reliability problems affected the engines in early bikes. Yamaha made several changes to solve the problems but the bike was withdrawn from most markets after 1974 and production stopped in the home market after 1975.
The TX500 and TX750 twins both featured a vibration control technology that Yamaha called an "Omni-phase balancer". In the TX750 two chain-driven shafts with bobweights counteracted vibrations generated in the engine, while the balancer in the TX500 was a simpler version with just a single balance shaft.
