How Much Power Does the 2023 GasGas MC 250F Make?

While KTM and Husqvarna moved to a new-generation platform of motocross and cross-country models last year, GasGas stuck with the tried-and-true motorcycles it had used since 2021. For all of the red Austrian models, this meant a familiar suspension and chassis setup. In the case of the MC 250F, it retained the same fuel-injected liquid-cooled DOHC four-stroke 250cc engine with a 78.0 x 52.3mm bore and stroke. Those dimensions give it a 3mm smaller bore and 3.8mm longer stroke than the 2023 KTM 250 SX-F and 2023 Husqvarna FC 250.

With those powerplant differences among others, the 2023 MC 250F spun less peak horsepower and torque than its Austrian cousins. With a Dunlop D404 street tire on its rear wheel, we documented 40.3 hp at 13,600 rpm and 19.2 lb.-ft. of torque at 9,000 rpm on our in-house Dynojet 250i rear-wheel dynamometer. Despite not churning out the highest peak figures in the class and having a noticeable dip in the horsepower and torque curves from 3,400 rpm to 5,800 rpm, the MC 250F engine won over many testers with its characteristics on the track.

“The GasGas engine is possibly the most fun of all the 250 four-stroke motocross bikes,” test rider Allan Brown said. “There’s decent roll-on power with tons of top-end and great over-rev, which helps with giving the chassis a lighter feeling. Gear ratios are just OK with a slight gap between the second and third, which is a common characteristic on Austrian bikes.”
