Designed for optimised mass centralisation, the FC 450 crankcases arrange the shafts and engine internals in the perfect position to achieve the best possible handling. Manufactured using a high-pressure die-cast production process, the result is a thin, exceptionally strong wall thickness at the lowest possible weight.

CRANKCASES
DDS CLUTCH
The FC 450 features a dampened diaphragm steel (DDS) clutch that includes a single-diaphragm steel pressure plate instead of traditional coil springs. It integrates a damping system for better traction and durability. The clutch basket is a single-piece, CNC-machined steel component using thin steel liners, which ensures a compact overall engine design.
WP XACT FRONT SUSPENSION
New shim stack settings improve the overall balance, cornering agility, and riding comfort on the FC 450 for 2024. The 48 mm WP XACT forks are designed as a closed cartridge system with a capsulated, adjustable air spring and pressurized oil chamber for smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with a mid-valve damping system, together with a hydrostop, which applies a progressive damping force in the last 40 mm of travel, the forks provide precise feedback to the rider. The settings are easily adjusted via the single air pressure pre-load valve, as well as through easy access click adjusters for compression and rebound. Additionally, the air pump needed to adjust the fork's air spring pressure is provided as standard.
WP XACT SHOCK ABSORBER
The WP XACT rear shock offers 293 mm of travel. Inside the shock is a computational fluid dynamics (CFD) optimised main piston for improved initial comfort, which provides strong hold-up in all conditions. Differently sized holes in the shims, which feature updated stack settings for 2024 to improve balance and handling, allow them to open more easily, which reduces the overall stress of the oil flow. Complete with low friction SKF seals fitted throughout the linkage system, consistent damping, comfort, and traction are guaranteed with rebound and both high and low speed compression adjustable by hand.
The FC 450 continues as the flagship machine in the Husqvarna Motorcycles motocross line-up and delivers class-leading performance. The engine not only produces a broad spread of controllable power, but positions the shaft arrangements at the ideal centre of gravity to vastly benefit manoeuvrability. Retaining the advanced electronics and high-quality components throughout, the 2024 FC 450 is finished with ergonomic bodywork adorned with new white, yellow, and grey graphics, inspired by the Swedish heritage of the brand.
