Where can i find how much horsepower the 2008 dualsport motorcycles (like Kawasaki 250cc and Honda 230cc) have

I was looking at the Lifan LF200 GY-5 and wanted to see how they compare.|||http://bikez.com/ is a good website to get comparisons from. They don't always have h.p. ratings on all models, but will have loads of other info and you can view side by side comparisons with other models.|||go to the dealers on the internet click on the yr,make,of the bike it will tell you then compare to th next make|||my son owns the 125 lifan and it works great.
