While both types have their own advantages and drawbacks, I like the 4 stroke. My Whizzer is so American;relatively heavy, loud and inefficient. My Puch 2 stroke moped is smaller, quieter and has a more "modern" look, even if some say it looks gay. The Whizzer and the electric Ford Thinkbike are all that's currently running though. So 4 stroke it is!
