The Honda NSR250 and Honda RS250RW were race motorcycles manufactured by Honda Racing Corporation to race in the 250cc class of the Grand Prix motorcycle World Championship. Both names identified the factory specification bikes entrusted to works teams, while customer teams used the production racer Honda RS250R. The first bike debuted in 1985 as Honda RS250RW, then from 1986 to 2002 the factory bikes were named NSR250. In 2003 the RS250RW name was resurrected until the demise of the 250 cc class. Honda also mass-produced a road legal Honda NSR250R.
