I hope not also. Yamaha is the only Japanese company still doing R&D on a 2 stroke model (YZ250) and continuing to improve it each year so hopefully that model will stay around a bit longer, it is an awesome bike. Many of the woods riders still prefer 2 strokes which is why KTM still offers a full 2 stroke line up, but many woods racers are riding the YZ250. I know there aren't many motocross riders buying the YZ but hopefully there are enough woods guys buying them to keep it around.
