The 2019 Yamaha YZ250F motocross bike is raced by Monster Energy/Star/Yamaha Racing’s Dylan Ferrandis, Colt Nichols, Justin Cooper, and Mitchell Oldenburg. We ran it on our in-house Dynojet dynamometer to find out how much power it makes. We documented 37.45 hp at 12,390 rpm and 18.53 pound-feet of torque at 8,440 rpm.
