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.

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
