I don't think it's that hard to to understand why the big four went down the four stroke road. It probably wasn't all that difficult to see, or believe at the time that the envi'ros would crack the s@#$ts at the two stroke hydrocarbon problem sooner or later.
Given the other machines they were producing at the time, the crossover between road and off road wasn't that far apart and with improving technology getting closer all the time.
Once it could be seen that the future was multi valve per cylinder the investment dollars and R&D dollars made it bad economics to run two parrallel programs for two engine types.
So to help there business model along a little the major offroad sanctioning bodies were convinced that the two stroke was going to die and you might as well set up the rules so that the gov's and envi'ros could see they were at least trying to be responsable/green.
Problem was racing being what it is the thirst for more power from light weight got expensive and noisier and racing machines are'nt that clean anyway,
and as we know the two stroke didn't die, and of course some manufacturers didnt completely follow the Honda mantra, and they know the consumer will enevitably dictate the direction they go.
So now technolgy has caught up to the two stroke, and the big four are still resisting, probably because they have'nt got full return from there investment.
The air assist direct injected two stroke has the ability to decimate the four stroke world and they are hanging on by there fingertips, because it's all about money.
