2021 KTM 250 SX-F

Raw horsepower and leading torque figures, a proven chassis, and improved suspension settings make the 250 SX-F a well-rounded racebike right out of the box.

As winner of Dirt Rider’s Best Motocross Shootout for two consecutive years (2019 and 2020), the KTM 250 SX-F was bound to stoke the fires of competition, and so it did. While the Yamaha YZ250F took first place for 2021′s shootout, the KTM still followed closely behind taking second. Its strong and fast engine, nimble handling, tunable suspension, light weight, and excellent brakes continue to serve this machine well. Its high-rpm powerband makes it a suitable ride for intermediate and pro-level riders.

New inlay graphics, improved WP Xact air fork and WP Xact shock, along with the addition of new low-friction linkage bearing seals made by SKF are the updates seen for the 2021 model.

The KTM 250 SX-F is available for an MSRP of $9,299, $1,000 more than the YZ250F and Kawasaki KX250, but $100 cheaper than the Husqvarna FC 250.

The KTM 250 SX-F is powered by the same liquid-cooled, DOHC, 250cc four-stroke engine as its counterpart, the Husqvarna FC 250. In measuring the machine’s rear wheel power figures for the five-bike comparison, the SX-F produced the highest horsepower figures and second highest torque numbers: 41.1 hp at 13,700 rpm and 19.1 pound-feet of torque at 9,100 rpm.

While the engine doesn’t produce the strongest low-end power, it excels in seemingly endless top-end pull. Contributing to its low-end power performance and rpm recovery characteristics is the bike’s long gear ratios.

The SX-F’s proven chassis and light 232-pound weight make it easily maneuverable on the track. Stability at speed and corners, effortless cornering while standing, and narrow bodywork are notable praises we attributed to the model in the shootout.

The braking system on the SX-F is top of the class. The Brembo brakes with 290mm and 220mm discs, front and rear, provide a ton of braking power that quickly brings the machine to a stop.

Mile-per-gallon figures are currently unavailable.

Although test riders would prefer to swap out the wider-than-usual Neken handlebars, this did contribute to a large and roomy cockpit. The bike received praise for its comfortable seat and excellent ODI lock-on grips.

Traction control, launch control, and handlebar map selection are among the electronics featured on KTM’s four-stroke.

Warranty and Maintenance Coverage

The Austrian brand offers a 30-day limited warranty.

As a top performer in the past and present, the 2021 KTM 250 SX-F continues to be a high-quality four-stroke machine with a quality engine, chassis, and suspension package with a price to match.
