May 2005 Dirt Bike Magazine article "True Power-An Inside Look at the Real World of Honest Horsepower" Pg 84, shows a dyno graph comparing an 1994 KX500 VS. 2005 YZF450, wonderfull wonderfull graph, The stock KX peaked at 60hp! STOCK! @ 7,000 rmp and the YZF a mere 49@ 8'500 rpm Ha, I love it, But tell me why the hell these 450's hang with us? I dont get it, Hmmm....Check this out though, under the dyno chart there is some text and it says, and I quote...
"Want a dose of reality? All the fanfare that the new four-strokes are getting shows that they still are not in the realm of true horspower compared to the 500 two-stroke. You wonder why ty davis' of the world love the KX500; Look no farther than this. They not only made monster power early in the powerband, they (the CR and KX were close) peaked out at at the 60- horsepower mark.
Its like Danny LaPorte was saying," So lets see, after six years the big bore four-strokes are still heavier, slower and require higher mantenance than a decade-old design". (500's)
Wish I could post the graph some how but I dont have the equipment. So everyone Kill the four-strokes!!!
