Features and benefits

Frame

The hydro-formed, laser-cut and robot-welded frame is expertly crafted. Constructed with specifically calculated parameters of longitudinal and torsional flex, the frame provides exceptional rider feedback, energy absorption and straight-line stability. Additionally, the frame features forged brackets for mounting the standard skid plate on the FC 450 Rockstar Edition.

Rotational masses in the frame and the forged steering head connection have been specifically positioned to reduce chassis squat. Together with the shock mounting, which is not connected to the main tube, the anti-squat of the chassis has been enhanced for exceptional balance on acceleration and turning. Also, the frame wall thickness has been optimised to achieve exceptional reliability and specific rigidity in high stress areas such as the steering head and the shock mounts. Parallel frame mounts (same position on left and right sides) improve chassis flex characteristics, while stability characteristics remain unrivalled.

Another highlight of the frame topology is that the footrest mounting is positioned inwards, resulting in less susceptibility to catching in deep ruts or when scrubbing jumps. The footrests have been designed with the help of state-of-the-art Computational Fluid Dynamics (CFD) to provide the optimal contact area for the rider. The one-piece steering head seal allows easier mounting in case of replacement or service and offers improved reliability.

The frame of the FC 450 Rockstar Edition is finished in a fine structured, premium black powder coating. The standard frame protectors feature a specific topology, guaranteeing superior protection, durability, and advanced grip in any condition. Mounted with four screws, using the integrated frame brackets, the newly designed 2K carbon composite skid plate offers superior protection against dirt and hard impacts to the frame and engine.

Polyamide-reinforced aluminium subframe

Using 60% polyamide and 40% aluminium, the two-piece subframe has a total weight of just 1.8 kg. With the help of computational dynamics, specific rigidity was engineered into the light and robust subframe, delivering outstanding handling and rider comfort.

The lower subframe spars and frame mounts are made from cast aluminium profiles to guarantee robustness and reliability where needed. The upper subframe is made from injection-moulded polyamide, enabling specific flex characteristics and allowing a lightweight construction.

Topology-optimised polyamide/aluminium hybrid construction
Lower subframe spars and frame mounts made from (cast) aluminium profiles → extremely robust and reliable (no weld joints)
Upper subframe made from injection-moulded polyamide → specific rigidity and flex benefit handling and comfort

Swingarm

The hollow die-cast aluminium swingarm is designed to offer optimal stiffness and reliability at the lowest possible weight. The topology ensures perfected rigidity, while an improved casting process reduces weight. A 22 mm rear axle is fitted to match the chassis flex characteristics.

Additionally, the chain guard and chain slider have been specifically designed for improved durability and less susceptibility to catching on external objects. This design helps with reducing dirt build up around the swingarm and chain guard, especially in extremely muddy conditions.

WP XACT front fork with AER technology

The 48 mm split air fork features a capsulated air spring and pressurised oil chamber for progressive and consistent damping. Oil and air bypasses reduce pressure peaks and, in combination with a midvalve damping system, the fork provides exceptional feedback and rider comfort. The hydrostop improves bottoming resistance through more progressive damping force in the last 40 mm of travel. Additionally, rebound is also reduced leading to the fork being lower on initial acceleration after a hard landing. Updated shim stack settings focus on improved bike balance and more comfort while keeping needed front-end hold-up. This leads to significantly noticeable improvements in cornering agility.

Settings are easily adjusted via a single air-pressure preload valve, as well as via easy access click adjusters for compression and rebound. The fork protection ring increases protection against dirt intrusion on the fork seals. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard.

Easy access clicker dials → simple and fast clicker settings
Redesigned fork protection rings → increased protection against dirt intrusion

CNC machined triple clamps

Made from high-grade aluminium, the CNC-machined Factory Racing triple clamps feature optimally tuned steering stem stiffness, perfect alignment of the fork tubes, and precise geometry of the fork clamps to ensure highly responsive and smooth fork action. Maximum gains in handling are provided by simple offset adjustment of 20 mm or 22 mm.

The topology-optimised handlebar mounts provide maximised grip surface for less handlebar twist at minimal weight. Additionally, they allow for both rubber-damped and fixed mounting, providing customisable handlebar flex.

Rubber damped → less vibrations, precise front-end feel (OE)
Fixed → increased vibrations, more precise front-end feel

The front number plate integrates a triple clamp protector which covers the lower triple clamp and protects it from possible roost damage.

CNC-machined aluminium with anodised surface → finest quality and reliability
Perfect clamping and alignment → smooth fork action
Topology optimised handlebar mounts → Enhanced grip surface for less handlebar twist
Rubber damping on top clamp → reduced vibrations, increased comfort
Adjustable handlebar position → adjustable ergonomics

WP XACT rear shock

The Computational Fluid Dynamics (CFD) optimised main piston in the shock improves initial comfort and provides strong hold-up. Differently sized flow holes allow the shims to open more easily and reduce the overall stress of oil flow and pressure on the shims. Reduced weight also means less moving mass, resulting in lower forces on the main piston. Updated shim stack settings focus on improved bike balance and more comfort while keeping needed rear-end hold-up. This leads to significantly noticeable improvements in cornering agility.

A fully hand-adjustable dual compression control concept allows high and low-speed settings to be changed by hand. Together with the rebound adjuster, which is hand adjustable, riders are able to change their shock settings without tools and without the help of a mechanic at the racetrack.

On top of the tool-free setting adjustment possibilities, the preload adjuster is fine-tuned for increased resistance to dirt intrusion. The two-piece spring retainer allows for quick mounting without splitting the shock.

With its low-friction SKF linkage seals, 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 feel.

Grips and throttle assembly

The ODI lock-on grip on the left side does not require gluing, while on the right, the vulcanised grip features an innovative integrated throttle mechanism. The assembly has easy free-play adjustment and, by changing a cam, throttle progression can be altered. The ODI lock-on grips come standard in a softer, grey compound on the FC 450 Rockstar Edition.

Throttle assembly and ODI grips → easily alter throttle progression; easy grip mounting without glue

Footrests

The CFD designed footrests offer a bigger surface for boot soles while being less susceptible to catching on deep ruts, take-offs when scrubbing, or track barriers. The result is better control of the bike in all conditions. This was achieved by a narrow mounting concept integrated in the frame design, which also benefits of a low weight.

Topology optimised, die cast footrests → low weight and less susceptible to dirt build up
Footrest mount integrated in frame → narrow profile is less susceptible to catch on deep ruts

Map select switch, traction & launch control

Designed for easy and intuitive operation, the Map Select Switch comes as standard. It activates traction and launch control, selects between two engine maps (smooth/aggressive) and activates the Quickshift feature on the FC 450 Rockstar Edition. Map 1 is the standard map for linear, predictable power, while Map 2 is an aggressive map for added throttle response and more explosive power output.

The Quickshift function can be activated or deactivated via the Map Select Switch. The function works only when upshifting, interrupting the ignition for a fraction of a second. This allows upshifting while the throttle is fully opened without the use of the clutch lever. A sensor on the shift drum registers the force from the shift lever, sends the signal to the ECU and the ignition timing is interrupted. To prevent unintended shifts and false neutrals, the function is only active from 2^nd to 5^th gear.

With the engine at idle, launch control is engaged by pressing the traction control and Quickshift switch simultaneously. Both symbols will start flashing to indicate the launch control is active. This function limits the amount of power to the rear wheel, improving traction and preventing loss of control under hard acceleration. Once the rider shifts up a gear, the launch control will deactivate automatically. To benefit from the Quickshift feature during the launch control the QS button must be pressed before activating launch control. Otherwise, Quickshifter will not be available between 2^nd and 3^rd gear on the start.

Traction control on 4-stroke models is engaged by a switch marked ‘TC’ and functions by 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 ensuring maximum traction. This is a distinct advantage in wet or muddy conditions.

Handlebar Map Select Switch → alters engine characteristics according to conditions and rider preference
Quickshift function → clutch-free upshifting
Traction control → optimal traction in all conditions
Launch control → maximum traction for perfect starts

Start/Stop switch

The combined start/stop switch on the right side of the handlebar allows for easy, intuitive start and stop of the engine.

Engine Management System (EMS)

The Keihin EMS is specifically designed to be smaller, lighter, and faster at processing data. It integrates launch control for perfect starts, selectable engine maps via the switch on the handlebar, traction control, as well as the Quickshift function. Combined with the gear sensor, power delivery is tailored for each gear.

A Roll Over Sensor (ROS) kills the engine in case of extreme crashes, adding another level of safety to this generation of Husqvarna motocross machines. Additionally, the hour meter comes with an integrated FI status LED and a fuel level indicator.
