FC 450

Base Price: 10,690.00 EUR*

The pinnacle of Husqvarna motocross, the FC 450 uses advanced engineering techniques to not only draw 63 hp from the 450cc motor, but also position the engine shaft arrangements at the ideal centre of gravity to vastly benefit handling and manoeuvrability. The addition of launch control means perfect acceleration off the line, while class-leading ergonomics and traction control keep the rider in full control.

01. Performance

Powerful engine

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.

INTERCHANGABLE AIRBOX COVER

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 FC 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.

Lightweight frame

The chromium molybdenum steel frame harnesses 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 blue powder coating with standard frame protectors for superior protection and durability.

Carbon fibre subframe

Carbon fibre is renowned for its light weight and high strength. For those reasons, the Husqvarna MX range features a unique composite subframe made from 30% carbon fibre. Specific rigidity is engineered into the subframe to deliver optimal handling and rider ergonomics.

Crankshaft

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.

CNC machined triple clamps

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.

Magura hydraulic clutch

The reliable, high quality, German-made 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 hot or cold conditions, as well as over time.

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 that allows the use of thin steel liners and contributes to the compact design of the engine.

Functional bodywork

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.

WP XACT SUSPENSION

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 new 10mm shorter cartridges and outer tubes provide refined rigidity. In combination with a new 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. Together with the fully adjustable WP XACT rear shock, Husqvarna offers superior suspension performance, feeling and comfort.

Wheels and tyres

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.

BRAKES

The highest level of quality is guaranteed with class-leading Brembo callipers and controls. The 260 mm front and 220 mm solid rear discs deliver superior stopping power instilling confidence in any condition.

Map switch

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.

Engine management system

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.

44 mm throttle body

The FC 450 features a 44mm 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.

Electric start and Li-Ion battery

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.
