02. Maîtrise absolue

Habillage

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-mold technology for a high-quality, long-lasting finish.

Suspensions avant WP XACT

The high-performance WP XACT 48 mm split air forks feature new settings to match the revised frame and linkage, ensuring the motorcycle delivers 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.

Amortisseur WP XACT

Optimized 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.

Cadre

New engine mounts and a revised frame reduces overall weight while improving flex characteristics and stability, which is particularly noticeable 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 is fitted to protect the frame and engine from hard impacts.

Boucle arrière

The composite subframe is manufactured using advanced technologies. Constructed with a blend of 60% polyamide and 40% aluminum, the subframe weighs only 3.9 lb (1.8 kg) 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.

Bras oscillant

The aluminum 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 utilized. Additionally, the chain guard and glider have a smooth profile and offer outstanding durability.

03. Puissance inégalée

Moteur

Producing an impressive amount of power, the SOHC, 450 cc engine is the result of advanced engineering techniques and tips the scales at just 59 lb (26.8 kg). Mass-centralization of the major components was key during the design process, as was positioning the engine close to the center of gravity to aid handling and agility. The position of the engine inside the chassis ensures refined anti-squat behavior from the chassis for smooth acceleration across rough terrain.

Culasse

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

Cylindre et piston

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

Boîte de vitesse

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 enhances positive gear changes.

Embrayage DDS

The FC 450 Rockstar Edition is equipped with a DDS (Dampened Diaphragm Steel) 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 for better traction and durability. Complete with a CNC-machined steel clutch basket adapted for the five-speed transmission, the single-piece component allows the use of thin steel liners and contributes to the compact design of the engine.

Freins Brembo

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. A new, stronger rear brake pedal tip is less susceptible to damage for continued control.

04. Électronique de pointe

Sélecteur de cartographie

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 personalized 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.

Contrôle de la traction

Traction Control on the FC 450 Factory Edition is engaged by pressing the 'TC' button on the Map Select Switch. Analyzing 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.

Contrôle de départ

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. Additionally, Quickshift cannot be activated while Launch Control is engaged.

Démarreur électrique et batterie Li-ion

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 2.2 lb (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.
