2024 Husqvarna® FX 350, 2024 Husqvarna® FX 450

Benefitting from new WP XACT Closed Cartridge spring 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.

Features may include:

• Engine

The FX 450 engine benefits from advanced engineering techniques to deliver maximum performance. Low in weight and weighing just 59 lbs (26.8 kg), 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 redesigned SOHC cylinder head is incredibly compact with the camshaft positioned as close to the centre of gravity as possible for significantly improved handling and agility. A new, more durable fine punched cam chain runs on low-friction chain guides for optimal efficiency and improved reliability with a single oil spray jet guaranteeing 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.

• Cylinder and piston

The lightweight aluminium cylinder is undoubtedly an engineering masterpiece and features a 95 mm bore with a 63.4 mm stroke. Inside, the CP bridged-box-type piston features anodised annular grooves, adding durability and longer service intervals at a weight of just 327 g. For improved performance, the compression ratio has been increased to 13.1:1 to create an incredible peak power while maintaining its crisp responsiveness.

• Crankshaft

The crankshaft is specifically positioned to harness the rotating mass in the ideal centre of gravity resulting in a lightweight and agile handling feel. As such, the inertia produced by the crankshaft is carefully calculated to deliver optimal traction and rideability from the powerful 450cc plant. A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 90 hours.

• Crankcases

Designed for optimised mass centralisation, the FX 450
