The FS 450 engine benefits from advanced engineering techniques to deliver maximum performance. For 2023 the engine is lighter, weighing just 59 lb (26.8 kg), and is tilted two degrees backwards to further centralise mass for enhanced handling and significantly improved anti-squat behaviour from the chassis. Servicing of the FS 450 engine is made easier compared to previous models thanks to the addition of service markers on the engine cases. |
|
The SOHC cylinder head is incredibly compact with the camshaft positioned as close to the centre of gravity as possible for unrivalled handling and agility. A durable, fine-punched cam chain runs on low-friction chain guides for optimal efficiency and reliability with a single oil spray jet ensuring 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. |
|
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. Delivering best-in-class performance, the compression ratio is 13.6:1 for incredible peak power while maintaining its crisp responsiveness. |
|
Designed for optimised mass centralisation, the FS 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. |
|
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 450 cc engine. A plain big end bearing comprising two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 90 hours. |
|
Produced by Pankl Racing Systems, the 5-speed gearbox is designed to be extremely light and durable while featuring optimised and proven motocross-specific gear ratios (24:72). A redesign of the shift shaft reduces the operating forces required for gear changes. Integrated into the shift drum, a new Quickshift sensor can be activated by pressing the QS marked button on the map select switch to further aid seamless upshifting. |
|
The FS 450 features a Suter anti-hopping clutch to prevent rear wheel instability and hopping when braking hard into the apex of a turn for total control and perfect drifting. It reduces the physical efforts required by the rider and improves lap times. |
Ride Easier
Lightweight frame
The proven chromium molybdenum steel frame is refined for 2023. A new shock mounting, which is no longer connected to the main tube, significantly improves the anti-squat behaviour of the chassis. With optimised wall thickness in high stress areas improving reliability, the frame continues to offer advanced geometries and flex characteristics aimed at providing unparalleled rider feedback, energy absorption, and exceptional straight-line stability. The frame is finished off in a premium metallic blue powder coating with redesigned standard frame protectors offering superior protection, durability, and grip in any condition. Additionally, the inclusion of forged brackets on the lower frame rails allows for easy installation of the skid plate, which is available as a technical accessory. |
Polyamide-reinforced aluminium subframe
|
CNC machined triple clamps
Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps provide precisely calculated geometry for increased stability. Handlebar flex can be customised with the handlebar clamp, which offers two mounting options - rubber-damped for less vibration, or fixed for enhanced front-end feedback. 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.
|
WP XACT front suspension
The 48 mm split air forks offer impressive bottoming resistance thanks to the hydrostop, which applies a progressive damping force in the last 40 mm of travel. The WP forks are designed with a capsulated, adjustable air spring and pressurized oil chamber for smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with a mid-valve damping system, the forks provide precise feedback to the rider. The settings are easily adjusted via the single air pressure pre-load valve, as well as through easy access click adjusters for compression and rebound. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard. |
|
The WP XACT rear shock offers 266 mm of travel. Inside, a computational fluid dynamics (CFD) optimised main piston enhances initial comfort and 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, consistent damping, comfort, and traction are guaranteed with rebound and both high and low speed compression adjustable by hand. |
|
The 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 generations. In order to optimise and match the flex characteristics from the frame, a 22 mm rear axle is fitted. Additionally, the chain guard and chain slider have been designed for improved durability and are less prone to catching on external objects. |
Made from 60% polyamide and 40% aluminium, the two-piece subframe ensures exceptional strength and durability at an overall weight of just 3.9 lbs (1.8 kg). The lower subframe spars and frame mounts are manufactured from cast aluminium for significantly improved reliability. The upper section of the subframe is made from injection-moulded polyamide to enable specific flex characteristics and ensure a lightweight construction.
Effortless Ergonomics
Functional bodywork
Clean, Swedish-inspired design and ergonomics are tailored to allow riders to perform at their best for extended periods of time. Adapted after countless hours of testing, the contact points and surfaces in the rider triangle have been repositioned for 2023 to improve comfort on the motorcycle. A new, flatter seat offers unrestricted movement with a high grip cover ensuring riders stay firmly in place under hard acceleration. |
Airbox
Designed with precisely positioned inlet ducts aimed at reducing drag and air flow deformation, the airbox ensures unrestricted airflow with maximum filter protection. The Twin Air filter is easily accessed without tools, by simply removing the left side panel for easy maintenance. Offering further performance customisation, the FS 450 is delivered with an additional airbox cover that can be changed without the use of any tools for a sharper throttle response according to rider preference or track conditions.
|
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.
|
Hydraulic brakes
|
|
Developed between Husqvarna Motorcycles and leading handlebar manufacturer, ProTaper, the exclusive bend offers superior comfort, class-leading strength, and fatigue resistance at the lowest possible weight. |
|
ODI lock-on grips feature an innovative integrated throttle mechanism and a glue-free installation. The throttle assembly offers easy free-play adjustment with the option to fit alternative cams for a personalised throttle action. |
|
The CFD-designed footrests offer a large contact area to ensure better control of the machine and with a narrow mounting design, the footrests are less susceptible to catching on trackside barriers and obstacles. |
Exceptional stopping power is guaranteed with Brembo brakes, which feature a 4-piston, radially mounted monoblock calliper in combination with a 310 mm disc at the front. A single piston calliper and a 220 mm disc are fitted to the rear. The perfectly placed controls allow for optimal feel and balance in all conditions.

Black 16.5'' and 17'' Alpina spoked wheels on the front and rear respectively are lightweight and strong. Metzeler Racetec SM K1 125/75 R420 and 165/55 R420 slick tyres are fitted for maximum grip, traction, and agility. |
|
The exhaust system on the FS 450 features a flow-designed resonance chamber, which plays a vital role in delivering class-leading performance. Manufactured in two pieces and designed to be as compact as possible, the header pipe allows for the system to be removed without removing the rear shock. The silencer has a short and efficient design, moving weight closer to the centre of gravity and ensuring impressive power while keeping noise as low as possible. A black coating highlights its premium quality. |
|
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. |
|
A new and bigger 1.9 gal (7.2 litre) 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. |
Technologically Advanced
|
The intuitive handlebar-mounted Map Select Switch allows riders to activate Launch and Traction Control, enable the Quickshifter, and allow riders to toggle between two engine maps. The easy-to-operate component allows for quick changes to the engine characteristics based on track conditions and rider preference. |
|
The Quickshifter function can be activated or deactivated via the Map Select Switch and works by interrupting the ignition for a fraction of a second when upshifting. A sensor on the shift drum registers the force from the shift lever, sends a signal to the ECU, and ensures smooth gear changes - even when the throttle is fully open. To prevent unintended shifts and false neutrals, the function is only active from second gear upwards. |
|
With the engine at idle, Launch Control is engaged by pressing the Traction Control and Quickshifter buttons simultaneously. Both symbols will start flashing to indicate that 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, Launch Control will deactivate automatically. Additionally, the Quickshifter is deactivated when Launch Control mode is engaged. |
|
For personalised power delivery, the FS 450 has two built-in engine maps as standard. Map 1 (white) offers linear, predictable power, while map 2 (green) is more aggressive for a sharper throttle response and more explosive power output. |
|
The new Engine Management System (EMS) is designed to be smaller and lighter while being faster at processing data. It incorporates a new rollover sensor (ROS) which cuts the ignition and shuts off the engine in the event of a severe crash, adding another level of safety to Husqvarna Motorcycles' new generation supermoto. |
|
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. |
|
Along with the benefit of an easy electric starting system, a lightweight Li-Ion 2.0 Ah battery is fitted to the FS 450. The Li-Ion battery weighs approx. 2.2 lb (1 kg) less than a conventional lead battery meaning the convenience of electric starting is delivered while keeping overall weight to a minimum. |
|
The combined engine 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, but the removal of an additional stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall. |
