Does Husqvarna’s new 250F produce more peak horsepower and torque than the prior-generation model? To find out that and more, we ran it on our in-house dyno.
--
One of two completely revamped bikes in the 250 four-stroke motocross category for 2023, Husqvarna gave its FC 250 a redesigned engine that continues to have a high rev limit of 14,000 rpm. Bore and stroke measurements were changed from the prior-generation (2019–2022) models’ 78.0 x 52.3mm to a larger bore of 81.0mm and shorter stroke of 48.5mm. Inside the all-new cylinder head, titanium exhaust valves are 1.0mm larger and controlled by a redesigned exhaust camshaft.
Husqvarna says its new fuel-injected liquid-cooled DOHC four-stroke 250cc engine is 8mm lower in height and 60 grams less in weight. According to Dirt Rider’s in-house Dynojet 250i rear-wheel dynamometer, it’s also higher in both maximum horsepower and torque. We documented 41.7 hp at 13,400 rpm and 19.3 lb.-ft. of torque at 9,200 rpm, an increase at peak of 2 hp and 0.5 lb.-ft. of torque. With those figures, it makes the most peak horsepower and ranks second in maximum torque of the six bikes tested in our 2023 250F Motocross Shootout.
On track, testers noticed better midrange power as well as some characteristics that carry over from prior year models. “The FC 250 has soft low-end, but good high-revving ability and power that shines toward the top-end of the rpm range,” test rider Michael Wicker said. “I prefer the aggressive map 2 to get as much power as possible, and really enjoy the smooth shifting ability of its Pankl Racing Systems transmission.”
