The Honda CR250R was a Honda racing dirt bike. The prototype was built in 1971, but it was not until late 1972 that production of "out of the box racers" began. It was made available for sale to the general public in 1973. The CR250 was produced for nearly 37 years, 2007 being the final year of production.^[2]

Chassis: Starting in 1997, Honda started the first gen aluminum frames. The first gen frames were thick, rigid and were a big change from the previous steel frames. Then in 2000, Honda came out with the second gen aluminum frame, which was less rigid. It also had a smaller and thinner twin-spar aluminum frame, which provided the rigidity decrease. That made for better handling. Then in 2002, they came out with the third gen aluminum frame, which was thinner, and lighter. They kept the same frame with minor suspension changes until they stopped production of any 2-stroke in 2007.
