Yamaha YR2 350 Motorcycle - Street (1968-1969)

The Yamaha YR2 350 series, produced from 1968 to 1969, marked Yamaha's entry into the 350cc production motorcycle segment, establishing the foundation for future two-stroke parallel-twin models. In 1968, the YR2 was introduced, featuring a 348cc air-cooled, two-stroke parallel-twin engine producing 36 horsepower. Key updates from its predecessor included a five-port cylinder system for improved scavenging and a stiffer frame. Two trims were offered: the standard YR2 "Grand Prix" road bike and the YR2C "street scrambler." The YR2C distinguished itself with high-rise handlebars, an upswept exhaust, fork gaiters, and off-road oriented tires. For 1969, the model evolved into the YR3, retaining a similar 36 horsepower output from its 347cc engine. This iteration focused on refinement, offering a wider powerband and significantly reduced engine vibration. Notable changes included separate instrumentation (replacing the headlight-mounted unit) and color-matched side panels. The YR3C scrambler also received a redesigned seat and pea-shooter style mufflers. These changes represent a clear evolution of the platform.
