Husqvarna FX 450

Overview

The pinnacle of Husqvarna offroad competition, the FX 450 uses advanced engineering techniques to not only draw 63 hp from the 450cc motor, but also position the engine closer to the centre of gravity to vastly improve 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.

FUNCTIONAL BODYWORK

PHO BIKE DET Fx450 Bodywork 20 %23SALL %23AEPI %23V1

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. As a result of extensive testing, the slim contact points make shifting between riding positions easier and allow the rider to flow with movement. The flat seat profile, together with the seat cover texture, deliver superior comfort and control in all conditions.

WP XACT FRONT FORK 

PHO BIKE DET Mx 2019 Fork %23SALL %23AEPI %23V1

 

The 48 mm split air fork features a capsulated air spring and pressurized oil chamber for progressive and consistent damping. Pressure peaks were reduced through extended oil and air bypasses. 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.

 

WP XACT REAR SHOCK

 

 

With updated settings, the WP XACT rear shock provides advanced damping characteristics for unsurpassed traction and energy absorption. A pressure balance inside the shock ensures consistent damping, resulting in superior rider comfort and feeling. The fully adjustable component delivers 300 mm rear wheel travel, as well as unrivalled traction, feeling and energy absorption.

 

 

 

WHEELS AND TYRES

 

 

Made from high-strength alloy rims by D.I.D and featuring CNC-machined hubs, the wheels of the FX 450 are fitted with DUNLOP GEOMAX tyres with proven design for progressive cornering and superior grip on a variety of terrain.

 

 

components

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 clamp works in harmony with the front forks, 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 FX 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.

 

electronics

MAP SWITCH

Designed for easy, one-finger operation, the map switch is standard on the FX 450 and serves multiple functions. It allows the 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.n.

 

44 MM THROTTLE BODY

The FX 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 FX 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.

POWERFUL ENGINE

The SOHC engine is the perfect example of the advanced engineering techniques used by Husqvarna motorcycles offering class-leading HP at an overall weight of just 61.3 pounds. Mass-centralization is key in the engine design, enabling chassis engineers to position the engine closer to the center of gravity for optimal handling and maneuverability.

GEARBOX

 

 

A lightweight 5-speed gearbox produced by PANKL Racing Systems ensures the highest level of durability and reliability. The gear lever also features a unique design that prevents dirt build-up and keeps the lever tip in its original position, even in the toughest conditions, while an advanced gear sensor selects the ideal engine map for each gear.

LIGHTWEIGHT FRAME

The chromium molybdenum steel frame is expertly crafted using laser-cut, robot-welded, hydro-formed tubes, ensuring the highest level of precision and quality. The specifically crafted geometry utilises advanced longitudinal and torsional flex characteristics, for 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.

 

COMPOSITE CARBON FIBRE SUBFRAME

The carbon composite subframe is unique to Husqvarna Motorcycles and showcases advanced production technology and innovation. Using 70% polyamide and 30% carbon fibre, the 2-piece subframe has a total weight of just over 1 kg. With the help of computational dynamics, specific rigidity was engineered into the light and robust subframe, delivering outstanding handling and rider comfort.
