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 Fluid 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.
Swingarm
The new hollow die-cast aluminium swingarm is manufactured from a single piece of aluminium using an improved die-cast production process for optimal stiffness and a 190 g weight reduction over previous versions. In order to optimise and match the flex characteristics from the new frame, a new 22 mm rear axle is fitted. Additionally, the chain guard and chain slider have been completely redesigned for improved durability and are less prone to catching on external objects.
Bodywork
Clean, Swedish-inspired design and ergonomics are tailored to deliver exceptional comfort and control, enabling riders to perform at their best for extended periods of time. Adapted after countless hours of testing, the contact points have been repositioned for 2023 and together with a flatter seat profile, riders can move freely on the motorcycle for total control at all times.
Tool-less airbox
Easy access to the TWIN AIR filter is possible without tools, for quicker cleaning and easier maintenance. Precision inlet ducts maximise airflow and offer increased levels of filter protection.
Hydraulic clutch
The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation and perfect modulation in every condition. Meaning that play is constantly compensated so that the pressure point, and function of the clutch remain identical in cold or hot conditions, as well as over time. Countless hours of race focused testing have proven the high-quality, Italian-made Brembo hydraulic systems exceptional reliability.

The muffler features an aluminium mounting bracket for strength at the lowest possible weight, with an advanced internal construction ensuring excellent noise damping without sacrificing performance.
Cooling system
Manufactured from high-strength aluminium, the radiators are designed using Computational Fluid Dynamics (CFD) to channel air in the most effective way. A large centre tube channels coolant through the frame to reduce pressure at this point in the system for a more consistent flow while a new internal thermostat further enhances reliability.
Fuel tank
A new 2.24 gallon fuel tank integrates neatly into the revised bodywork. Due to the new fuel pump design and position, the tank is emptied further for increased running times. For improved safety, the external fuel line is specifically routed to make it less exposed and susceptible to damage.
Map select switch
A redesigned and intuitive handlebar-mounted map select switch allows riders to activate launch and traction control, and allows riders to toggle between two engine maps. The easy-to-operate map select switch allows racers to quickly alter and set up the engine characteristics on a race by race basis dependent on track conditions and rider preference.
Quickshift
The new quickshift function can be activated or deactivated via the map select switch. The function works only when upshifting, interrupting the ignition for a fraction of a second. This allows upshifting while the throttle is fully open without the use of the clutch. A sensor on the shift drum registers the force from the shift lever, sends the signal to the ECU and the ignition timing is interrupted. To prevent unintended shifts and false neutrals, the function is only active from second gear upwards.
Mapping
For personalised power delivery, the FX 450 has two built-in engine maps as standard. Map 1 offers linear, predictable power, while Map 2 is more aggressive for a sharper throttle response and more explosive power output.
E-Start
As with all 4-strokes in the Husqvarna range, the FX 450 starts with the ease of pressing a button thanks to electric start. A lightweight Li-Ion 2.0 Ah battery is fitted, giving the convenience of electric starting while keeping overall weight to a minimum.
Engine management system
The KEIHIN EMS is designed to be small, lightweight and fast at processing data. It integrates traction control for perfect starts, selectable engine maps via the switch on the handlebar, as well as launch control.
Hour meter
A new hour meter comes with an integrated fuel level indicator, which is visible on the FI status LED, indicating to the rider when the fuel level is becoming low.
Start/stop switch
The new combined start/stop switch is located on the right side of the handlebar for easy, thumb-operated use. Not only simplifying the starting and stopping of the engine, the removal of a designated stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall.
Traction Control
Traction control on the FX 450 is engaged by a button marked ‘TC’ on the Map Select Switch and functions by analysing throttle input from the rider and the rate at which engine RPM increases. If the RPM increases too quickly, the engine management system (EMS) registers a loss of grip and reduces the amount of power to the rear wheel to ensure maximum traction. This is a distinct advantage in wet or muddy conditions.
