Charts explained
Here is what our radar gun tells us about our six finalists and the fastest and slowest bikes in the Torture Test. The top chart is the best performance each bike made in front of the radar gun in a full pull going up an inclined 775-foot dirt drag strip. Aside from the KLX160 and its massive horsepower disadvantage, traction plays a substantial role in any dirt launch, and if it had been included, the Christini AWD KX450F would have looked the best until 35 mph. Right at about 30 mph horsepower really starts coming into play, and as the speeds increase, the bikes' engines show what they're made of. The fastest bike in our run, the Zip-Ty Racing Husky 450 just edges out the Am-Pro Yamaha WR450 in pull. Interesting is the difference between the stock KTM 250 XC and the modified Pro-Action 300 XC dancing back and forth. The top speed shows the peak achieved during the run-great information for bench racing, we've heard.
