2024 HUSQVARNA FX 450

POWERFUL ENGINE

The FX 450 engine benefits from advanced engineering techniques to deliver maximum performance. Low in weight and weighing just 26.8 kilograms, the engine is designed to centralise mass for enhanced handling and significantly improved anti-squat behaviour from the chassis. Servicing of the engine is made easier compared to previous models thanks to the addition of service markers on the engine cases.

CYLINDER HEAD

The SOHC cylinder head is incredibly compact with the camshaft positioned as close to the centre of gravity as possible for unrivalled handling and agility. A durable, fine-punched cam chain runs on low-friction chain guides for optimal efficiency and reliability with a single oil spray jet ensuring effective cooling. The lightweight valves are actuated via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.
 
 
 
 
 
 
 
 
 

GEARBOX

Produced by Pankl Racing Systems, the 5-speed gearbox is designed to be extremely light and durable with a revised transmission ratio of 29:72 offering smooth and precise shifting. Integrated on the shift drum, the Quickshifter can be activated via the Map Select Switch to further aid smooth upshifting.
 
 
 
 
 
 
 
 
 
 

DDS CLUTCH

The FX 450 features a dampened diaphragm steel (DDS) clutch, which 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.
 
 
 
 
 
 
 
 

Benefitting from new WP XACT front forks for 2024, the FX 450 retains its class-leading performance and continues to headline the Husqvarna Motorcycles offroad line-up. With an engine that not only produces a broad spread of usable power, but also positions the engine shaft arrangements at the ideal centre of gravity to centralise mass, the FX 450 offers a lightweight feel for all riders. Aiding this is the chassis which has been developed and manufactured using advanced engineering techniques to offer improved anti-squat behaviour for impeccable handling and manoeuvrability. Retaining its advanced electronics and high-quality components throughout, the FX 450 is complete with a flat profile seat, ergonomic bodywork, and finished with yellow and grey graphics inspired by the Swedish heritage of the brand.
