By 1990, the last year of RC30 production, the bike finally went on sale in the United States, about three years after its Japanese debut. It remained the same hand-built homologation machine with a gear-driven-cam V4 and single-sided swingarm, by then a proven winner at the Isle of Man TT. About 3,000 were made before the fuel-injected RC45 took over.
