I have heard two different stories and I'm wondering which one is true. You take 2 bikes... say a raptor and a banshee for example. (One being a four stroke and the other being a two stroke of course). Lets say they both make 100hp on the dyno. Then you take them to the sand and drag race them, both have equal riders and are correctly set up. I have been told that 2 strokes make power differently and you need a little more hp on a 2 stroke to be faster. Then I have been told hp is hp. So who wins?
