This model embodied a high-level marriage of comfort when cruising on the expressway, running stability and the kind of spirited riding feel that customers wanted in a motorcycle. In the quest for high performance, high durability and high reliability, this model adopted unique Yamaha technologies in features like its compact, laterally-aligned DOHC 3-cylinder engine and a maintenance-free shaft drive. The next year the GX750II was introduced with a 3 into 2 muffler and a big boost in power up to 67 ps.
