FC 450 FACTORY EDITION 2025

01. Finest Componentry

FMF titanium exhaust

As used by Rockstar Energy Husqvarna Factory Racing in AMA Supercross and Pro Motocross competition, the FMF Factory 4.1 RCT silencer is a championship-winning component. Beautifully crafted with a blue anodised titanium body and finished with a carbon fibre end cap, the silencer is considerably lighter than standard, slightly shorter to centralise mass, and delivers a notable boost to overall performance.

Factory wheel set

Superior craftsmanship at its finest. Black anodised EXCEL Takasago rims laced to black CNC-machined hubs using high-quality spokes create an exceptionally strong pair of wheels. Incredibly robust while saving weight, the Factory Wheel Set contribute to the overall handling of the FC 450 Factory Edition thanks to the reduction in unsprung weight.

Factory triple clamps

Featuring a unique clamping design for perfect fork alignment and uncompromised suspension performance, the CNC-machined Factory Racing Triple Clamps are fully adjustable to offer true customisation. With a choice of two offset positions, 20 mm or 22 mm, as well as the option to install the handlebars with rubber mounts for added comfort, or without for a more precise front-end feel, a personalised set-up can easily be achieved.

Pro Taper handlebar

Second to none when it comes to function and style, the ProTaper handlebar is lightweight and incredibly strong. The specifically selected bar bend reduces pressure points on the rider's hands with soft compound ODI lock-on grips offering additional comfort.

Tyres

Delivering best-in-class performance, the Dunlop GEOMAX MX34 tyres feature a race proven 'block-within-a-block' design for progressive cornering and exceptional grip on a wide variety of racing surfaces.

Bodywork

Slim-profile bodywork ensures unrestricted movement on the motorcycle, while the high-grip GUTS Racing seat cover holds riders firmly in place under hard acceleration. The ergonomic bodywork features the latest Rockstar Energy Husqvarna Factory Racing graphics, which are applied using in-mould technology for a high-quality, long-lasting finish.

WP XACT front suspension

The high-performance WP XACT 48 mm split air forks feature settings developed to work in unison with the advanced chassis for the highest level of comfort, balance, and cornering agility. With oil and air bypasses reducing pressure peaks, in combination with a midvalve damping system, the fork provides exceptional feedback from the front wheel. A hydrostop system creates a more progressive damping force in the final 40 mm of travel for improved bottoming resistance on hard landings.

WP XACT shock absorber

Optimised linkage geometry and low-friction seals ensure the fully adjustable WP XACT shock delivers exceptional performance. In addition to offering 300 mm of rear wheel travel, the WP shock offers progressive damping, energy absorption, and confidence-inspiring cornering agility.

Frame

The advanced chassis is both strong and lightweight, with a carefully calculated level of flex, which is particularly advantageous when braking into corners. The frame itself is expertly crafted from hydro-formed, laser-cut, and robot-welded steel and finished with a premium white powder coating for a true race team look. Constructed with specifically calculated parameters of longitudinal and torsional flex, the chassis provides exceptional rider feedback, energy absorption, and straight-line stability. Additionally, a 2K carbon composite skid plate protects the frame and engine from hard impacts.

Subframe

The composite subframe is manufactured using advanced technologies. Constructed with a blend of 60% polyamide and 40% aluminium, the subframe weighs only 1.8 kilograms and is incredibly durable. Designed with the assistance of computational dynamics, specific rigidity has been engineered into the subframe to enhance overall handling and rider comfort.

Swingarm

The aluminium swingarm is designed for optimal stiffness and durability thanks to the proven die-casting process that ensures the lowest weight possible. To further accentuate the flex characteristics from the chassis, a 22 mm rear axle is utilised. Additionally, the chain guard and glider have a smooth profile and offer outstanding durability.

Engine

Producing an impressive amount of power, the SOHC, 450 cc engine is the result of advanced engineering techniques and tips the scales at just 26.8 kilograms. Mass-centralisation of the major components was key during the design process, as was positioning the engine close to the centre of gravity to aid handling and agility. The position of the engine inside the chassis ensures refined anti-squat behaviour from the chassis for smooth acceleration across rough terrain.

Cylinder head

An incredibly compact SOHC cylinder head positions the camshaft as close as possible to the centre of gravity to aid overall handling and agility. Lightweight valves are actuated via a rocker arm while the timing is optimised to create impressive torque and ensure a precise throttle response.

Cylinder & piston

The lightweight aluminium cylinder is an engineering masterpiece. Inside the 95 mm bore, the CP bridged-box-type piston features anodised annular grooves for maximum durability and long service intervals.

Gearbox

Manufactured by Pankl Racing Systems, the five-speed gearbox is low in weight while offering incredible durability. A Quickshifter sensor fitted to the shift drum ensures smooth upshifts at all times, while a low-friction coating on the shifting fork further aids positive gear changes.

DDS clutch

The FC 450 Factory Edition is equipped with a Dampened Diaphragm Steel (DDS) clutch. Unique in design, the exclusive characteristics of this system include a single diaphragm steel pressure plate, instead of traditional coil springs, with an integrated damping system ensuring maximum traction and durability. Complete with a CNC-machined steel clutch basket, the single-piece component allows for the use of thin steel plates and contributes to the compact design of the engine.

Brembo brakes

Brembo brakes deliver class-leading braking performance. With a 260 mm floating front disc, protected by a 2K carbon composite front disc protector, and a 220 mm wave rear disc, the incredible stopping power created allows for late braking, which leads to faster lap times. Additionally, the rear brake pedal tip has been designed to be durable for a continued high level of control.

Map select switch

The intuitive handlebar-mounted Map Select Switch allows riders to engage both launch and traction control, enable the Quickshifter, and activate one of two engine maps. The easy-to-operate Map Select Switch allows racers to quickly alter the engine characteristics on a race-by-race basis depending on track conditions and rider preference.

Mapping

For a personalised power delivery, the FC 450 Factory Edition has two built-in engine maps as standard, which can be selected and engaged via the Map Select Switch. Map 1 (white) offers linear, predictable power while Map 2 (green) is more aggressive for a sharper throttle response and a more explosive power output.

Quickshifter

The Quickshifter function can be activated via the Map Select Switch and works by interrupting the ignition for a fraction of a second for smooth and precise gear changes, even when the throttle is fully open. The Quickshifter is only active from second gear onwards to help avoid accidentally shifting into neutral when moving from first to second gear.

Traction Control

Traction Control on the FC 450 Factory Edition is engaged by pressing the 'TC' button on the Map Select Switch. Analysing throttle input from the rider and the rate at which engine RPM increases, if the RPM increases too quickly, the Engine Management System (EMS) registers a loss of grip and reduces the amount of power to the rear wheel to ensure maximum traction. This is a distinct advantage in wet and slippery conditions.

Launch Control

With the engine at idle, Launch Control is engaged by pressing the Traction Control and Quickshift buttons simultaneously. Both symbols will start flashing to indicate that Launch Control is activated. Designed for race starts, this technology limits the amount of power to the rear wheel, improving traction, and helps to prevent loss of control under hard acceleration. Once a gear change is made, Launch Control deactivates automatically.

Electric start and Li-Ion battery

Keeping overall weight to a minimum and ensuring fast, reliable starting, the Li-Ion 2.0 Ah battery fitted to the FC 450 Factory Edition is approximately 1 kg lighter than a conventional lead battery. Additionally, the electric start and engine stop buttons are located inside the same housing for a simplified experience.
