In fact it is possible to make an emissions-compliant 2-stroke engine, yet it would be harder to justify from a marketing standpoint after some countries effectively banned the imports of new 2-stroke motorcycles around 2008, and some of those countries in fact have a larger motorcycle market than the United States. Not to mention the latest successful 2-stroke engines became more concentrated around lower displacement brackets.
