In 2001, Yamaha released their most recent SR250 due to popular demand for reliable commuters. This model is modeled after the SR500. Despite sharing the SR designation, these bikes are very different. The engines are different in the most fundamental sense and the frames are also very different - no seat or tank components are interchangeable without frame modification.
