The 250X will bring a smile to just about anyone’s face, while the 450FX is more of a race-ready all-encompassing machine. The two-stroke is light, flickable, and fun to ride. Although the power is broad—thanks in part to the wider gearbox ratios—the 250X didn’t lose the grunt of the motocross version. The Kayaba “spring” suspension is also excellent for off-road—plush, predictable, and comfortable. Where the 250X lacks, the 450FX clearly pulls ahead, as the bigger four-stroke is much easier to ride in slick conditions and far more stable at speed. Much like the two-stroke, the 450FX’s suspension is equally as plush and well balanced; however, the power delivery and stability of the four-stroke elevates the bike above the 250X. It’s difficult to beat a modern four-stroke’s power and reliability. But if you’re looking for a bike that is fun to ride and will get you in and out of anything, the two-stroke is a solid choice too.
