The church is in session! The 2025 KTM 350 SX-F is arguably one of the most fun bikes to ride/race. If you’re looking for a place to start with your suspension settings, look no further. We feel these settings could help your KTM 350 SX-F become more balanced and help you enjoy your moto day more.
Suspension: Try these settings if you’re anywhere near the 175-200 pound mark. This setting, along with the other chassis mods here (after an 8 hour break in period) should help the KTM feel less harsh and settle more. The Husqvarna FC350 has a different suspension spec so this setting will not work. IT TAKES 6-8 HOURS FOR THIS SUSPENSION BREAK IN!
Fork:
Height: 2-3mm (helps with stability)
Air Pressure: 10.8 bar
C: 14 out
R: 15-16 out
Shock:
Sag: 103mm
LSC: 12 out
HSC: 1.5 out
R: 16 out
Torque Specs: (This will works with Husqvarna and Gas Gas as well) Even though some engineers say that torque spec doesn’t really matter in the grand scheme of “feel” on the bike, my body says different. The KTM chassis feels slightly rigid from the swingarm pivot bolt back as I get a lot of deflection (side to side) movement out west on braking bumps as well as acceleration bumps. Lowering the torque spec on the swingarm pivot bolt to 95 Nm helps settle the rear end slightly as well as helps the rear of the bike keep straight (less side to side movement) during off throttle situations. This will not give you added comfort, but will help settle the chassis with less side to side movement (mostly on-throttle type situations). Keep an eye on your swingarm pivot nut as it will back out over time (vibration) so either blue Loctite it or check it every now and again. The stock plastic frame guards will hide it and you will never know it’s backing out until it’s too late and your pivot bolt screws up your swingarm bearings
