Default Re: difference in a 4 stroke and 2 stroke motor

The beauty of a china girl engine is they're tuned for low hp, wide power band. You can run them down to almost 1000 rpm, and they'll still take full throttle, and run up to 7000 plus, which wouldn't be all that high of a rpm on a high hp 2 stroke.

That's a good design feature for a bicycle with a motor.
