How Much Power Does the 2024 KTM 250 SX-F Make?

Dyno testing KTM’s 250cc four-stroke motocrosser for horsepower and torque.

KTM has a solid track record of manufacturing some of the most powerful bikes in the 250cc four-stroke and 450cc motocross bike segments, and that rings true once again for 2024.

In the case of the 250 SX-F, its fuel-injected liquid-cooled DOHC four-stroke 250cc single-cylinder engine sends an impressive 42.8 hp and 19.8 lb.-ft. of torque to the rear wheel when run on our in-house Dynojet 250i rear-wheel dynamometer. Compared to class competitors, it ranks second in peak horsepower and tied with GasGas’ MC 250F for runner-up in maximum torque.

KTM’s 250 SX-F shines at high rpm, which is where it needs to be ridden to get the best performance out of it,” test rider Michael Wicker said. “Gears are long, quickshift (QS) is beneficial on starts, and traction control (TC) is nice to have for slick conditions. Also, I’m always impressed with this bike’s smooth shifting and the consistency of its Brembo hydraulic clutch.”
