Qingqi QM200GY-BA Super Motard

[forchetto]

Hey i live in Colombia South America and im about to get a QM200GY, bu i have a doubt... thing is they advertise the bike here as if it had 18 hp, but everywhere i look on the web i see qingqi says it has arround 15, the sales manager here says, they have a special version, because they simply asked qingqi to make the bike that way for our country... CAN THAT REALLY BE TRUE???

The only thing I can think of is that for South America you might not need the emissions gear that the European bikes have. For example mine has an oxidation Catalyser inside the muffler, and the exhaust pipe close to the head has a port for a SAI (secondary air injection). Both could reduce the power to about the 15.4 HP they advertise in Europe.
As the engine comes from a Suzuki DR200 and that makes about 20HP, I wonder what other things have changed, for example, the carburettor in Europe is 28mm, but the Suzuki's is 31 mm. Do you know what size carb is used in South America?.
