Might be cheaper to buy a used 600cc sport bike if you want to go fast. To make significant horsepower will cost a bucket of money. A ZX-6R makes 112 hp out of the box which is about 40 percent more hp than the ol' CB and it handles better as well. Of course, you will have to invest in one of those leather crotch rocket riding suits and I personally wouldn't want the public to see in one of those outfits... scare the little kids and make the adjust ill I suspect.
