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.
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.
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.
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 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.
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 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.
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.
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 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.
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 solid rear discs deliver superior stopping power instilling confidence in any condition.
