The Honda motorcycle built for World Superbike homologation and limited to about 3,000 units was the Honda VFR750R, also known as the RC30.
Honda Racing Corporation created the VFR750R as a road-legal racing special so Honda could compete with a production-based motorcycle in the World Superbike Championship. It was released in Japan in 1987, followed by Europe in 1988 and the United States in 1990.
The RC30 used a 748 cc liquid-cooled 90-degree V4 engine, gear-driven camshafts, a lightweight chassis and a single-sided swingarm. Its solo-seat layout and expensive hand-built construction reflected its racing purpose rather than mass-market practicality. Approximately 3,000 examples were produced.
The Honda RVF750 RC45 is the most likely source of confusion. It was the VFR750R’s successor and also a World Superbike homologation special, but only about 200 were manufactured worldwide. The CBR900RR and NR750 were limited or significant Honda models, but they do not match this specific RC30 description.
