No limits
Enhanced with multiple chassis refinements to take on-track performance to an even higher level, the 2024 FC 450 Rockstar Edition sets a new standard for competition-focused motocross machinery.
New engine mounts, together with a revised, lighter frame and updated suspension settings improve agility and stability to create a confidence inspiring riding experience.
Ergonomics are further improved with the addition of new tank shrouds while advanced rider aids, specifically chosen Technical Accessories, and the latest race team graphics complete the build of this premium machine.
The all-new WP XACT rear shock is 100 g lighter and 15 mm shorter than its predecessor yet the travel remains unchanged. Inside the shock is a Computational Fluid Dynamics (CFD) optimised main piston for improved initial comfort which provides strong hold-up in all conditions.
Matching the new frame design and suspension set-up, the CNC-machined triple clamps provide precisely calculated geometry for increased stability.
The upper triple clamp is stiffer to ensure a smoother fork action and plays a vital role in the perfect alignment of the front wheel for superior handling.
The 48 mm split air forks now offer improved bottoming resistance thanks to a new hydro stop, which applies a progressive damping force in the last 40 mm of travel for even greater comfort.
Additionally, the air pump needed to adjust the fork’s air pressure is provided as standard.

Factory Racing Triple Clamps
Producing a peak power of more than 63 Hp, the SOHC, 450 cc engine is the result of advanced engineering techniques and tips the scales at just 26.8 kilograms. Mass-centralisation of the key components was key during the design process, as was repositioning the engine closer to the centre of gravity for improved handling and agility.
This was achieved by tilting the engine 2 degrees backwards, which resulted in the countershaft sprocket being positioned 3 mm lower. The end result is significantly improved anti-squat behaviour from the chassis for smoother acceleration on rough terrain.
Map select switch
A redesigned and intuitive handlebar-mounted map select switch allows riders to activate launch and traction control, enable the new Quickshifter functionality, 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.
Quickshifter
The new Quickshifter 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.
Traction Control
Traction control on the FC 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.
Launch Control
With the engine at idle, launch control is engaged by pressing the traction control and Quick shift buttons simultaneously. Both symbols will start flashing to indicate the launch control is active. This function limits the amount of power to the rear wheel, improving traction, and preventing loss of control under hard acceleration. Once a gear change is made, the launch control will deactivate automatically. Additionally, the Quickshifter function is deactivated while launch control mode is engaged.
Mapping
For personalised power delivery, the FC 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.
Create and adjust the set-up of your FC 450 Rockstar Edition by pairing the new Connectivity Unit Offroad with the Ride Husqvarna Motorcycles app on your smartphone.
Once downloaded, the easy-to-use app offers full control of all engine settings including power delivery, engine braking, and the sensitivity of the Quickshifter. In addition to being able to customise the characteristics of the engine, recommended suspension settings that are based on a variety of racing surfaces, are pre-installed on the app.
The Rider section on the Ride Husqvarna Motorcycles app provides vital feedback to the rider post-race by offering full analytics of how the machine is being ridden, as well as recording lap times, which are added to a virtual leader board.
