I also like the THEORY of a 2t engine, rode 2t bikes for years, also drove trucks w/Detroit diesel engines, Great truck engines, and more power per cubic than a 4t, however the bikes fell short in my expectation in engine life, as I had to replace pistons on a regular basis, especially the road bikes, because miles piled up faster, also altitude was always a problem, heat was more of a problem w/2t's than 4t's. And smoke at high altitude was a serious problem for anyone behind me. So the switch to 4t's for me was good, If they ever produce a 2t, that will not smoke, seize, run crappy at high altitude, or wear out pistons & cylinders 3 times as fast as a 4t, count me in.
Cool because its actually a lot closer than you think. Bill Gates
threw about 25 million dollars a couple years to a small company called Ecomotors. They have built a 296lb 2 stroke with all the emission advantages of a 4 but the power to weight advantages of a 2. It puts out 325hp@3500rpms 664 lbs of torque at 2100rpms. The technology used to charge the engine is incredible and it looks like it is moving into production stage soon. Obviously this would need some adaptions and time to ever move into a bike but the concept is proven for a clean 2 stroke with massive power and superior fuel economy in a lighter weight package.
Its a pretty cool read about the motor. They designed a turbo with a supplimentary electric motor to eliminate turbo lag, which in this case would critical to starting the engine.
