Powerful engine
The FC 450 engine benefits from advanced engineering techniques to deliver maximum performance. For 2023 the engine is lighter, weighing just 59 lb, 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 FC 450 engine is made easier compared to previous models thanks to the addition of service markers on the engine cases. |
Cylinder head
The redesigned SOHC cylinder head is incredibly compact with the camshaft positioned as close to the centre of gravity as possible for significantly improved handling and agility. A new, more durable fine punched cam chain runs on low-friction chain guides for optimal efficiency and improved reliability with a single oil spray jet guaranteeing 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. |
Cylinder and piston
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. For improved performance, the compression ratio has been increased to 13.1:1 to create an incredible peak power to ensure the FC 450 remains firmly at the front of the pack. |
Crankcases
Designed for optimised mass centralisation, the FC 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. |
DDS clutch
The FC 450 features a Dampened Diaphragm Steel clutch, which includes a single-diaphragm steel pressure plate instead of traditional coil springs. It integrates a damping system for better traction and durability. The clutch basket is a single-piece CNC-machined steel component, which has been revised to accommodate the new gearbox in 2023, and continues to allow the use of thin steel liners that contribute to the compact design of the engine. |
Gearbox
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 (29:72). 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. |

CNC machined triple clamps
Matching the new frame design and suspension set-up, the CNC-machined triple clamps provide precisely calculated geometry for increased stability. Customised handlebar flex can be achieved by the new 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 suspensionThe 48 mm split air forks now offer improved bottoming resistance thanks to a new hydrostop, which applies a progressive damping force in the last 40 mm of travel for even greater comfort. 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 midvalve 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. For improved durability, new fork protection rings prevent dirt intrusion. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard. |
|
WP XACT shock absorberAn 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. |
|
SwingarmThe 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 hooking on external objects. |

For increased traction and stability through ruts, the FC 450 is fitted with a 120/90-19 rear tyre while a 80/100-21 front tyre ensures optimal grip on a variety of riding surfaces. |
Exhaust system
The exhaust system on the FC 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. |
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 1.9 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.

|
|
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 ControlWith the engine at idle, launch control is engaged by pressing the traction control and Quickshift 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 Quickshift 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. |
|
EMSThe 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 for safety in the event of a severe crash, adding another level of security to the Husqvarna Motorcycles' new generation motocross line-up. |
|
Hour meterA 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 switchThe 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. |
|
Electric startThe convenience of a lightweight starter motor and compact battery set-up means starting the motor, or recovering from a stall effortlessly, is as simple as a push of a button. |
