Shock wave of power

The FC 450 takes Husqvarna back to the very top of Motocross. It is imbued with power and breathtaking force, encased in a lightweight and cutting-edge chassis. Thanks to the 60 hp power plant and a wave of torque across the entire rev range, the FC 450 is a supreme example of what Husqvarna stands for: raw performance at the pinnacle of motorsport. And with a chromoly frame matched to a composite rear subframe and electric start, it is also one of the most advanced Motocross bikes on the market.

The FC 450 takes Husqvarna back to the very top of Motocross. It is imbued with power and breathtaking force, encased in a lightweight and cutting-edge chassis. Thanks to the 60 hp power plant and a wave of torque across the entire rev range, the FC 450 is a supreme example of what Husqvarna stands for: raw performance at the pinnacle of motorsport. And with a chromoly frame matched to a composite rear subframe and electric start, it is also one of the most advanced Motocross bikes on the market.

ENGINE

Exceptional power in a compact SOHC design layout delivers class-leading engine performance by maximising cutting-edge technology. The extremely wide power band of the FC 450’s engine allows riders to confidently tackle any track, and the high-tech engine management system combined with the super-smooth 5-speed gearbox and light clutch action, are sure to deliver race winning performance at every level.

CYLINDER HEAD

The FC 450’s engine is characterised by a single overhead cam that actuates four lightweight titanium valves via lightweight and rigid rocker arms (DLC coated on the intake). The broad power band of the FC 450 stretches to 11,500 rpm, peaking at 60 hp while maintaining exceptional torque low in the rev range. A three layer head gasket is used to guarantee durability.

PISTON

The König bridge-box-type piston was developed to reduce engine vibration and optimise strength. The compression ratio is 12.6:1 for an amazing peak output of 60 hp.

COUNTER BALANCE SHAFT

Vibrations are kept to a minimum on the FC 450 thanks to the multifunctional counter balance shaft. The side-mounted shaft cancels inertia forces and drives the water pump and timing chain, contributing to the compact layout of the engine.

FRAME

The priority in designing the frame was to meet strict performance goals while maintaining optimal torsional rigidity, longitudinal stiffness and extreme lightness, while offering excellent feedback and instilling complete confidence in the rider. To achieve their goals, the engineers designed the lightweight chromium molybdenum frame with precise longitudinal flex that helps absorb impacts from the rear wheel, working together with the suspension for better comfort and giving the rider greater feedback. The torsional rigidity, on the other hand, has been optimised to enhance turn-in, sharp handling and stability even on the roughest terrain, giving the rider complete confidence in finding his lines and increasing his pace lap after lap.

SUBFRAME

For the first time in Husqvarna’s centennial history, the engineers designed a composite rear subframe united with a chromoly frame. The three-piece composite subframe, made of high strength polyamide with a precision injection moulded production process, has been designed to offer stiffness while flexing more than an aluminium subframe, complementing the flex characteristics of the frame in order to offer optimum rider feedback and feeling in all conditions. The lightweight design offers engineers unlimited opportunities in integrating features such as all the electronics and the airbox.

SWINGARM

The design of the swingarm has been optimised according to the stiffness characteristics of the rest of the chassis. In order to give maximum rider confidence and comfort, while making the most of the Husqvarna engine characteristics in terms of traction and power, the aluminium swingarm has specific flex characteristics. The single-component casting process eliminates welding and guarantees consistent behaviour and quality. Strong but light, the beautifully styled aluminium cast swingarm provides perfect stability and safety.

BRAKES

Exceptional stopping power is guaranteed by the latest generation of Brembo brakes, featuring a new master cylinder and floating calipers in combination with 260mm wave discs at the front and 220mm wave discs at the rear. The perfectly placed controls allow for optimal feel and balance under extreme conditions.

FRONT SUSPENSION

WP suspension stands for top quality and offers the best performance levels. Adjustability is a key factor in tailoring a motorcycle according to varying requirements. With the WP forks, the ease of changing clicker settings is as simple as a twist of a dial, allowing all riders to adapt the rebound and compression damping settings to their own riding styles and track conditions. The 48mm closed cartridge front fork, matched with CNC machined black triple clamps, feature 300mm of travel and ensure exceptional handling and feel of the front end, thanks to accurate and consistent damping characteristics of the closed cartridge technology.

REAR SUSPENSION

The high performance DCC (Dual Compression Control) rear shock made by WP suspension is adjustable in rebound and high/low speed compression, and guarantees excellent comfort and world class damping. Combined with the white colour of the frame, the white spring gives the all-new Husqvarna Motocross bikes a striking appearance.

REAR LINK

The Husqvarna linkage system has excellent characteristics in fast and flowing sections. Due to its progressive characteristics it takes big hits in its stride, offering great rider comfort in all situations, even on the roughest track sections and the biggest jumps. The versatile linkage system is sure to meet the need of riders of all levels, with a consistent, confidence-inspiring and light feeling chassis in every situation.

CNC MACHINED TRIPLE CLAMPS

As on the other major components of the chassis, the CNC machined triple clamps have precisely engineered flex designed into them that allows the fork tubes to flex under stress. This gives the rider more feeling under braking and on landing off jumps. They are designed to evenly distribute the clamping force on the fork leg, maximizing contact area for optimal sensitivity and minimum friction. In addition, the handlebar can be mounted in 4 different positions.

DISTINCTIVE LOOKS

Traditional Husqvarna white, blue and yellow adorns the newly designed Motocross range, enhancing the modern styling.

ERGONOMICS

Tightly wrapped around the engine and frame, Husqvarna’s new bodywork is designed to connect the rider’s body to the bike, for a perfect fit of man and machine, allowing for total control in all conditions for the most diverse body sizes.

HANDLEBAR

Tapered 827 Renthal Fatbar handlebars feature a Renthal bar pad and are mated with Husqvarna grips for excellent control of the bike.

EQUIPMENT

Standard equipment includes handguards and map switch, as well as some of the best components on offer in the motocross segment, such as Brembo brakes and hydraulic clutch. For the die hard enthusiasts, riding pleasure and visual appeal can be further enhanced by a complete range of Husky Power accessories.
