You are having difficulty with the numbers because the dealers do not understand the difference between the Imperial System, and the Metric system. You see, most of the china bike dealers are not too bright, so we have to deal with problems related to their stupidity.
Some of the websites list the 11.5 number as horsepower when it is kw and visa versa. I have also seen the NM (metric) torque numbers given as HP.
The engines are all the same, as is their power output for both watts/HP and torque in NM/foot pounds.
The real question is how was it measured? Was it measured with the choked to death carb and exhaust system complete with cat? Or was the engine measured on the bench unrestricted? Are we trying to get back up to the listed power, or are we working up from those numbers?
When you take one of these CG engines, no matter what the factory numbers were listed as, properly tune the carb and replace the exhaust it feels and acts like you are doubling the power.
Derestricting and proper tuning increased my top speed from 45mph to 60mph. Others here have had the same experience, or better.
