After 19 hours aboard Yamaha’s new dedicated off-road 2-stroke, the YZ250X, it is proving to be more than capable of tackling any terrain. From first gear rocky climbs, to fast desert trails, this bike has been put through the wringer in the past several months. In order to take the 250X out and see how it did on public trails, an FMF Turbine Core 2 silencer was installed because the stock muffler isn’t equipped with a spark arrestor. Seeing as how this bike was designed for cross-country racing, we jumped at the opportunity for the bike’s first real test, a tight and rocky sprint enduro. Throughout the day at the enduro we paid close attention to the changes that Yamaha had made from the motocross bike that make the “X” more off-road capable. The changes made to the fork and shock work well on flowing trails and small trail chop providing a plush, progressive ride even when speeds are picked up. The only time we found the suspension to be uncompliant was when the whoops got very deep and far apart, or when we came up on large drop offs or g-outs. The power delivery of the “X” in stock form was strong from the bottom to mid-range, but the power softened when revved. The FMF Turbine core helped the mid to top-end slightly, along with adding bottom end with the installation of the FMF Gnarly pipe.
