This U.S.-market two-stroke sport bike arrived in the mid-1980s as part of Yamaha’s celebrated liquid-cooled, reed-valve twin family. It was developed during a period when the company was trying to preserve the appeal of high-performance two-stroke street machines just as emissions pressure and the rise of four-stroke rivals were reshaping the market. The result was a lightweight, sharply styled road bike with a direct connection to Yamaha’s racing heritage and to the company’s earlier production-racer-inspired street models.
In Yamaha history, the broader RZ 350 story began in Japan in 1981, where the original machine quickly earned a reputation for its lively character and earned an enthusiast following far beyond its home market. The North American N-code version is generally associated with the 1984 and 1985 model years, with the later bikes reflecting updates and market-specific variations rather than a revived second run. Among riders, it became especially admired for its combination of simple two-stroke character, compact size, and everyday road-bike usability wrapped in a true performance package.
Today it is remembered as one of the defining Japanese two-stroke street motorcycles of its era: not a long-production model, but a cult classic that helped close out an important chapter in Yamaha’s air-and-liquid-cooled sport-bike history.
