Benefitting from multiple technical upgrades for 2023, the FX 450 retains its class-leading on-track performance and continues to headline the Husqvarna Motorcycles off-road line-up. With an all-new 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, accentuating the lightweight feel of the FX 450. Aiding this agile feel is the new chassis which has been developed and manufactured using advanced engineering techniques to offer improved anti-squat behaviour for enhanced handling and manoeuvrability. Retaining the advanced electronics and high-quality components throughout, the FX 450 is complete with a new flatter seat and finished with functional bodywork adorned with white, yellow, and grey graphics inspired by the Swedish heritage of the brand.
Designed for optimised mass centralisation, the FX 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.
An all-new design results in a 15 mm shorter rear shock, which is 100 g lighter compared to the previous generation while the rear wheel travel is set at 293 mm. Inside the shock is a Computational Dynamics (CFD) optimised main piston for improved initial comfort which provides strong hold-up in all conditions. Different sized holes in the shims allow them to open more easily which reduces the overall stress of the oil flow. Complete with low friction SKF seals and a revised linkage system, consistent damping, comfort, and traction are guaranteed with rebound and both high and low speed compression now adjustable by hand.
