After successful Filth Rider’s 250F Motocross Shootout twice (2019 and 2020) and ending runner-up in one other two (2021 and 2022) with its prior-generation mannequin, one would possibly assume KTM would proceed refining that bike. However the Austrian producer isn’t one to settle and be content material, so its 2023 motocross vary was given an entire overhaul. Though the revamp didn’t catapult the 250 SX-F again to the highest spot, the orange machine retains a runner-up place amongst a stacked subject of rivals—not a straightforward feat to perform within the first yr of an all-new platform.
2023 KTM 250 SX-F Engine
Spinning the drum on our in-house dyno, the orange steed makes 41.5 hp and 19.5 lb.-ft. of torque, inserting it second in peak horsepower and first in most torque. Midrange is healthier than ever, however at the price of some over-rev. Nonetheless, the KTM stays a category chief in top-end energy, as evidenced by its spectacular dyno numbers. Backside-end is common and there’s nonetheless some engine vibration felt within the handlebar and footpegs. The Brembo hydraulic clutch on the KTM, Husqvarna, and GasGas works flawlessly, and is better of the bunch.

2023 KTM 250 SX-F Suspension
A contest-focused setup of its WP Xact 48mm air fork and WP Xact shock give the KTM the most effective suspension packages within the class. It’s the firmest setting of the Austrian trio, and provides extra consolation than the Honda’s and Kawasaki’s suspension, however isn’t as plush because the Yamaha’s.
Riders can assault the monitor with confidence figuring out the WP elements will maintain up, however the fork rides excessive within the stroke and goes via it too shortly at instances. Just like the Husqvarna, its fork hydrostop is simply too efficient at stopping bottoming and limits the quantity of usable journey. The shock doesn’t compress as a lot beneath acceleration in comparison with the prior-generation mannequin, and the flexibility to regulate its damping by hand is yet one more trade first from KTM.

2023 KTM 250 SX-F Chassis/Dealing with

A sophisticated electronics suite with two engine maps, traction management, launch management, and QS, and suspension that may be adjusted by hand sweetens the deal that rather more.

Extra low-end energy, extra constant fork motion, and a plusher suspension really feel are what the KTM must win this comparability sooner or later.
