The Honda NSR250R is a street-legal road-orientated 249cc two stroke sport bike produced by Honda Motor Co., Ltd between 1987 and 1999.
It evolved from the popular NS250R MC11 and was produced over four distinct generations, each powered by liquid-cooled, reed valve inducted 249cc 90° V-twin two stroke engines. All engines incorporated the Honda RC-Valve power valve system, and nikasil-sulfur lined cylinder bores (hence the 'NS' in 'NSR').
The road going NSRs were built in the image of the Honda RS250R (also known as the NSR250) production race motorcycle series, although they shared no mechanical parts. This was in the style of competing factories Yamaha and Aprilia.
