It's a YZ 250. They are trying to say that with the class CC changes, the 2-strokes will be popular again.

It's working in my neck of the woods. Only 2-strokes can race the 125 class- 250F's have to race with 250 2-strokes.

Yeah, they were just trying to look at the 2-stroke 250 as if it had just been invented. How if it had, people would be praising it as a all new, far superior motor design. So now that it is allowed to race the 250 4-strokes, you can now look at it like a new technology. Simpler, more powerful, and faster.
