2025 Husqvarna FC 450 Technical Overview

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

While some assume Husqvarna’s FC 450 is a KTM 450 SX-F dressed in different clothing, that’s not the case. The FC 450 differentiates itself from comparable models that are also owned by Pierer Mobility Group (the 450 SX-F and GasGas MC 450F) and others in the 450cc motocross bike segment with a 10mm-lower suspension setup, which gives it a low seat height of 37.4 inches (according to our measuring tape) and positive handling characteristics—namely cornering prowess. Prior to our annual 450 Motocross Shootout, we took a moment to get up close and personal with the 2025 Husqvarna FC 450, and have highlighted some of its features here as well as what differentiates it from the competition.

Husqvarna’s FC 450 sees a mid-generation update for 2025. The biggest change is its reworked double-cradle chromoly steel frame.Jeff Allen
Husqvarna says its fuel-injected liquid-cooled SOHC four-stroke 450cc single-cylinder engine weighs 59.1 pounds.Jeff Allen
On Dirt Rider’s dyno, the FC 450 hits 53.0 hp at 9,100 rpm and 32.7 lb.-ft. of torque at 7,000 rpm.Jeff Allen
Like KTM’s 450 SX-F and unlike GasGas’ MC 450F, the FC 450’s header pipe features a resonance chamber.Jeff Allen
The FC 450 has relied on a Brembo hydraulic clutch system since 2022.Jeff Allen
Quickshift (QS) was first seen on the FC 450 Rockstar Edition in 2022, and same goes for the combined engine start and stop switch on the right side of the ProTaper handlebar.Jeff Allen
A quick way to tell a 2025 Husqvarna FC 450 from a 2023–2024 model (aside from the graphics) is the former’s use of cutout engine mounts.Jeff Allen
According to Husqvarna, refinements made to the swingarm result in a longer-lasting chain slider.Jeff Allen
Another component shared with the 450 SX-F but not the MC 450F are CNC-machined triple clamps. Standard fork height is at the second line (pictured here).Jeff Allen
The WP Xact AER 48mm closed-cartridge fork on Husqvarna’s full-size motocross bikes is brand-specific being that it’s 10mm shorter than comparable models from KTM and GasGas. The WP Xact shock is lowered by 10mm as well via different shock linkage.Jeff Allen
Of the standard-model 450cc motocross bikes from Austria, Husqvarna’s is the only one to come with D.I.D DirtStar rims.Jeff Allen
Gearing is common among the trio of standard-model Austrian 450cc motocross bikes at 13/51.Jeff Allen
Brembo brakes have been a staple on the FC 450 since it hit the market in 2014.Jeff Allen
Husqvarna altered the seat for MY25, making it slightly higher and wider.Jeff Allen
In addition to radiator shrouds, fork guards, and rear fender all being switched to white, the Austrian brand decked out its FC 450 with fresh graphics.Jeff Allen
On our automotive scales, Husqvarna’s MY25 standard 450cc motocross bike weighs 239 pounds wet.Jeff Allen
