The only sense I can think of is that they are afraid of the tree huggers creating more bs laws. 4 of 6 bikes in my garage are two strokes. The duel sport DR250 doesn't get ridden/fixed because there's too many idiots in cars.
The klx110 is great for chasing the kids around on the pw and kdx50. When the kids are bigger the klx will be gone.
Eventually it will be all two strokes for us, if Junior ever thinks he needs a 250f he can get a job or 2.
