2024 Husqvarna FC 450 Technical Information

Features and specs of Husqvarna’s 2024 standard-model 450cc motocrosser.

Husqvarna’s FC 450 stole much of the limelight in the 450cc motocross bike segment last year thanks to a complete overhaul. It continues to differentiate itself from class competitors (including KTM’s 450 SX-F and GasGas’ MC 450F) with a lower suspension setup, which it’s had since 2021. The Austrian brand revised suspension settings on its flagship motocross bike for 2024, and gave it a new high-grip seat cover and mildly altered radiator shroud graphics. Before we publish our first ride review of the 2024 Husqvarna FC 450, let’s take a closer look at some of the details and features that make it a premium offering in the category.

The 2024 Husqvarna FC 450 isn’t dramatically different from the 2023 model. In addition to revised suspension settings, the Austrian brand gave it a new high-grip seat cover and radiator shroud graphics.Jeff Allen
According to Husqvarna, the FC 450 mill weighs 59 pounds.Jeff Allen
When run on our in-house dyno, the FC 450’s fuel-injected liquid-cooled SOHC four-stroke 450cc single-cylinder engine pumps out 55.6 hp at 9,900 rpm and 33.9 lb.-ft. of torque at 7,200 rpm.Jeff Allen
Unlike GasGas, Husqvarna and KTM use a flow-designed resonance chamber integrated into the header pipe on their respective flagship motocross bikes.Jeff Allen
Constructed of 60 percent polyamide and 40 percent aluminum, the two-piece subframe is similar to that of KTM’s, but with less airbox ventilation.Jeff Allen
Husqvarna and its Austrian cousins use 1.8-bar radiator caps in stock trim. This latest-generation design makes them quite difficult to remove, so checking coolant is a bit more of a chore.Jeff Allen
Engine start and stop buttons are within thumb’s reach on the right side of the handlebar.Jeff Allen
Electronics abound, the FC 450 offers riders two engine maps, traction control (TC), launch control, and quickshift (QS).Jeff Allen
This sticker on the frame serves as a reminder of which map is which, and how to activate launch control.Jeff Allen
Husqvarna’s full-size standard-model motocross bikes use a WP Xact 48mm air fork that’s 10mm shorter than KTM’s and GasGas’.Jeff Allen
The WP Xact shock is like the ones found on the orange and red Austrian rides, but Husqvarna uses a different linkage that makes the rear of the bike sit 10mm lower.Jeff Allen
Once accessed behind a plastic cover, the shock’s low- and high-speed compression damping adjusters are easily turnable by hand.Jeff Allen
Shock rebound adjuster can be moved by hand as well, and there’s a slot for a flat-blade screwdriver to make it even easier.Jeff Allen
The FC 450, FC 350, and FC 250 feature Excel rims in 2024, while the TC (two-stroke motocross), TX (two-stroke cross-country), and FX (four-stroke cross-country) models still use D.I.D hoops.Jeff Allen
CNC-machined triple clamps have a 22mm offset. Engraved pinch bolt torque specifications are a nice touch.Jeff Allen
Stock sneakers are Dunlop’s Geomax MX33, which have now been replaced by the Geomax MX34 as Dunlop’s soft-to-intermediate-terrain motocross tires.Jeff Allen
Brembo brakes contribute to the FC 450’s status as a premium offering.Jeff Allen
In addition to calipers, Brembo also supplies the brake and clutch master cylinders. Levers are adjustable by hand using the black knobs.Jeff Allen
A ProTaper handlebar comes standard with a bend unique to Husqvarna models.Jeff Allen
Although it doesn’t cover the entirety of it, Husqvarna is the only manufacturer to offer bottom triple clamp roost protection in stock trim.Jeff Allen

Husqvarna’s fuel tank isn’t the largest-capacity in the class (that honor belongs to GasGas’ MC 450F), but is generous by motocross standards at 1.9 gallons.Jeff Allen
The 2024 Husqvarna FC 450 weighs 241 pounds wet on Dirt Rider’s automotive scales.Jeff Allen
