It is quite a bold move for Honda to eliminate all US 2-strokes. For the diehard CR fans the way to go will be north to Canada for importing. The other manufacturers should see an increase in motocross 2-stroke sales, but the death of the 2-stroke comes quickly upon us and Honda is promoting it. This is certainly good news for enviro-freaks, but in the big picture, does it really make much of a difference. My feeling is that even the modern 4-stroke is antiquated in ways and that there should be more development towards alternative power sources, or at least use of alternative fuels for the 4-stroke. Whichever bike manufacturer gets to the hot setup first (probably Honda) will be sittin' pretty when it comes time to convert.
Lets not forget... FERRARI turned to Honda for engineering help on it's mid 90's F-1 engines (last 3 years of the 4-stroke V-12s), in an effort to produce more power, more reliability and lower frictional losses. Note I am not comparing Ferrari to Honda, I happen to be a big fan of both companies.
