Radar Runs
Once again, we brought our favorite toy-the radar gun-to a comparison. Why? Well, mostly because we like shooting the radar gun and telling our friends how fast bikes go, but it's also a great comparison tool. As you can tell by looking at the runs below, each of our 24-Hour modified 250Fs is unique. Sure, we had them undertake a motocross-style start to show where the bikes are making power and, more important, traction.Right away, you'll notice a tall orange line. That's the KTM. No big surprise there. In fact, the KTM would be the smart money for almost every holeshot, and if you need a good start, the KTM is a good place to, well, start. The softness of the bottom-end helps the bike with traction down low and gets you to the motor's launch point effectively. Then it pulls away, killing everything in sight until the Yamaha finally catches up around 70 mph.Speaking of the blue bike, did you notice how steep that line is? That's aggressive acceleration from a powerful motor. The bike is the slowest on bottom, not because it isn't making power, but more so due to the rear wheel spinning like crazy. A YZ and WR mixed-breed is snappy for sure and, once under control, a pretty wild ride.The Honda occupies the middle road. The modified X pulls great off bottom and through the mid, then tapers off consistently and smoothly. It doesn't fall on its face at all, even though, when compared with the other two fire-breathers on this chart, it seems to do just that. The great part about this power is you can short-shift and grunt around at speed with enough pull to loft the front or jump out of trouble. For long hours on the trail, this is hard to beat.
