2023 Husqvarna FX 350 Technical Information

What’s new on the 2023 Husqvarna FX 350?

Updated: October 16, 2022

The 2023 Husqvarna motocross and cross-country models are all-new. This is not just some hype about tweaks, adjustments, and improved settings. The bikes are completely revamped, featuring a new frame, subframe, swingarm, engine, WP Xact shock, and bodywork. The WP Xact 48mm air fork from earlier models will still fit with the front wheel, but that’s about it. We compiled some detailed photos showing some of the new features offered on the 2023 Husqvarna FX 350. Check them out below.

The engine features a new cylinder, cylinder head, and cases. It has a plain bearing connecting rod, 88.0mm piston, a compression ratio of 14.6:1, and a 13,400 rpm rev limit. There’s also a six-speed gearbox.Mark Kariya

The new swingarm is die-cast and topology-optimized to provide optimal rigidity and is said to be 190 grams lower in weight.Mark Kariya

A smaller 22mm rear axle is used to match the new chassis flex characteristics.Mark Kariya

The lower one-piece cast subframe spars have no weld joints for increased reliability, and the upper subframe is made of injection-molded polyamide. A key feature is that the subframe can flex and return to its original position in the event of a crash.Mark Kariya

New die-cast footrests are lighter, less susceptible to dirt buildup, and less likely to hook on deep ruts because of a new mounting position that is more integrated into the frame.Mark Kariya

The electronics are neatly tucked away under the seat. The new one-piece fuel pump is designed to improve fuel supply and further empty the tank, allowing for extended running times. The external fuel line has been relocated to make it less exposed and susceptible to damage too.Mark Kariya

New handlebar mounts sit atop CNC-machined 22mm-offset triple clamps. The new lower support features a one-piece assembly that can be either rubber mounted for more comfort and less vibration or solid mounted for a more precise front end feel but with slightly more vibration.Mark Kariya

New handlebar switches clean up the cockpit. On the left is the map select switch, and on the right is a multifunction engine start/stop switch. The FX 350 does not have a traction control (TC) option, and because it has a six-speed gearbox, there is no quickshift (QS) mode either.Mark Kariya

A new fixture attached to the top triple clamp has a multifunction design. Husqvarna uses it to hold the hourmeter and new wiring harness connectors for the handlebar-mounted switches. It’s also the mounting point for the front number plate.Mark Kariya

An added accessory that was not included on prior year cross-country models is the new polyamide composite skid plate. It’s just big enough to be very functional but not overkill, and features openings large enough to allow air to flow and mud and water to escape.Mark Kariya

The FX 350 comes with a 2.25-gallon polyethylene fuel tank that is larger than the FC 350 motocrosser’s by 0.35-gallon, but you would never know it by how narrow and open the cockpit is. All the additional volume is located in the lower areas of the fuel tank.Mark Kariya
