The FX 450 offers class leading performance in a lightweight, capable package. All aspects are designed to offer exceptional performance in conjunction with rider comfort and ergonomics making the FX 450 equally appealing to amateur and professional off-road riders alike. Traction control, map select and WP AER 48 forks are just a few of the standard features which ensure the FX 450 embodies premium quality and feel.
The SOHC engine is the perfect example of the advanced engineering techniques used by Husqvarna motorcycles offering a peak power of 63 hp at an overall weight of just 61.3 pounds. Mass-centralization is key in the engine design, enabling chassis engineers to position the engine closer to the center of gravity for optimal handling and maneuverability.
The inertia produced by the crankshaft is carefully calculated to deliver optimal traction and ride-ability from the powerful 450 cc plant. The crankshaft is specifically positioned to harness the rotating mass in the ideal center of gravity resulting in a lightweight and agile handling feel. A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 100 hours.
The crankcases are designed to house the shaft arrangements and internals of the engine in the position that offers the best possible centre of gravity. Additionally, the position of the clutch shaft keeps the clutch above the oil level resulting in decreased friction and increased efficiency.
Integrated cooling system
The radiators are expertly crafted by WP Performance Systems using high strength aluminium. CFD (computational fluid dynamics) is utilized to channel air through the radiators more efficiently and provide optimal cooling in all conditions. The cooling system is integrated into the frame increasing heat dissipation by channelling coolant through the frame while eliminating the need for additional hoses. Additionally, the radiator protectors do not only protect against flying debris but also act as a brace divert any energy from an impact around the radiator and into the frame.
