Hidden GEM - Yamaha, the renowned Japanese motorcycle manufacturer, is synonymous with exotic designs and powerful performance. However, in the early 1970s, Yamaha ventured into uncharted territory by secretly developing a motorcycle equipped with a Rotary/Wankel engine, known as the Yamaha RZ201.

During this period, the engine for the Yamaha RZ201 was developed exclusively by Yanmar Diesel, a Japanese company licensed by NSU for Rotary/Wankel engine production. The motorcycle's sketches and designs, bearing the project code YZ587, received approval on August 22, 1972, and were officially unveiled to the public for the first time at the Tokyo Motor Show in the same year.

The presence of the Yamaha RZ201 at the exhibition was a monumental surprise, even for Yamaha's own employees. This project had been shrouded in secrecy at Yanmar Diesel, with only a select few within Yamaha being privy to its existence.
In terms of design, the Yamaha RZ201 shared many components with the Yamaha TX750 and GL750, including the fuel tank, frame, front dual-disc brake system, suspension, and various other elements. What set the RZ201 apart was its utilization of a Rotary engine with two rotors, giving it a distinct appearance compared to other Yamaha motorcycles available at that time.

The Yamaha RZ201 served as a testament to Yamaha's determination to penetrate the motorcycle market, which was then dominated by European brands and other Japanese competitors. Notably, it was the first Japanese motorcycle to employ a Rotary engine. Armed with a dual-rotor Wankel engine, the Yamaha RZ201 possessed undeniable power, positioning it as a formidable competitor to the 4-stroke motorcycles of its time.
