The pinnacle of Husqvarna motocross, the FC 450 uses advanced engineering techniques to not only draw massive power figures from the 450cc engine, but also position the engine shaft arrangements at the ideal center of gravity to vastly benefit handling and maneuverability. The addition of launch control means perfect acceleration off the line, while class-leading ergonomics and traction control keep the rider in full control.
For 2022 we upgraded the hydraulic clutch to an all new high-performance Brembo system for perfect modulation at all times. On top, striking new dark blue and white graphics stylishly adorn the Swedish inspired design.
“some see obstacles, others see opportunity. whatever the challenge, make sure you’re up for it.”
Discover what sets the Motorcross FC 450 apart from the rest.
Clean, Swedish-inspired design and ergonomics are tailored to deliver exceptional comfort and control, enabling riders to perform at the highest level for extended periods of time. Adapted after countless hours of testing, the contact points are specifically positioned to allow seamless movement around the motorcycle.
The 48 mm split air fork features a capsulated air spring and pressurized oil chamber for progressive and consistent damping. Extended oil and air bypasses reduce pressure peaks and 300mm cartridges and outer tubes provide refined rigidity. In combination with a midvalve damping system, the fork provides exceptional feedback and rider comfort. The setting is 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.
Made from high-strength alloy rims by D.I.D and featuring CNC-machined hubs, the wheels of the FC 450 are fitted with DUNLOP MX33 Motocross tyres with proven "block-within-a-block" design for more progressive cornering and superior grip.
The highest level of quality is guaranteed with class-leading Brembo callipers and controls. The 260 mm front and 220 mm rear discs deliver superior stopping power instilling confidence in any condition.
The SOHC cylinder head is incredibly compact and lightweight using a short profile with the camshaft located as close to the center of gravity as possible, significantly improving handling and agility. The lightweight valves are actuated via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.
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 450cc plant. A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 100 hours.
The 22 mm offset CNC-machined triple clamps feature an integrated rubber damping system that reduces vibration and increases rider comfort. The triple clamps have been meticulously designed to evenly distribute the clamping force on the fork leg, maximizing contact area for optimal sensitivity and minimal friction and offering superior handling and stability. Additionally, the front number board integrates a triple clamp roost protector.
The new, 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 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 that allows the use of thin steel liners and contributes to the compact design of the engine.
Designed for easy, one-finger operation, the map switch is standard on the FC 450. This allows riders to easily select between 2 engine maps, activate the launch control or toggle the traction control feature.
The KEIHIN EMS is designed to be small, lightweight and fast at processing data. It integrates launch control for perfect starts, selectable engine maps via the switch on the handlebar as well as traction control.
The FC 450 features a 44 mm Keihin throttle body. The injector is positioned to ensure the most efficient flow into the combustion chamber while to ensure optimal throttle response the throttle cable is mounted directly without a throttle linkage providing more immediate throttle response and feeling.
Along with the benefit of an easy electric starting system, a lightweight Li-Ion 2.0 Ah battery is fitted to the FC 450. The Li-Ion battery weighs approx. 1 kg less than a conventional lead battery meaning the convenience of electric starting is delivered while keeping overall weight to a minimum.

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.
Made using high-strength aluminium, the cooling system on the FC 350 features computational fluid dynamics to channel air through the radiators more efficiently. The cooling system is also integrated into the frame allowing improved cooling by channelling coolant through the frame while eliminating the need for additional hoses.
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.
The FC 350 frame features an innovative, self-cleaning footpeg mount that helps prevent mud build-up, springing back to the original position for sure footing at all times.
