Yamaha’s YZ250FX generally receives changes similar to the YZ250F motocrosser one year later. This means 2022 brought updates that are rather inconspicuous, but notable, for the bLU cRU’s quarter-liter cross-country racer. The main power-focused revisions include a new intake port shape, different exhaust camshaft profile, higher-volume muffler, newly shaped airboot, and an optimized ECU setting. The rest of the 2022 Yamaha YZ250FX’s engine, suspension, and chassis updates are detailed in our technical information article.
Prior to being reviewed and included in a four-bike comparison test in Green River, Utah, we ran the updated off-road competition bike on our in-house dyno. With a Dunlop D404 street tire on its rear wheel, the YZ250FX spun 37.9 hp at 12,100 rpm and 18.3 pound-feet of torque at 8,800 rpm. Compared to last year’s model, that’s an increase of 0.1 hp at peak. Maximum torque is the same, although the 2022 model makes it at 400 rpm higher.
