CNC Machined Triple Clamps 8211 Matching the new frame design and suspension set up the CNC machined triple clamps provide precisely calculated geometry for increased stability Customised handlebar flex can be achieved by the new handlebar clamp which offers two mounting options 8211 rubber damped for less vibration or fixed for enhanced front end feedback The upper triple clamp is stiffer to ensure a smoother fork action and plays a vital role in the perfect alignment of the front wheel for superior handling

WP XACT Shock Absorber 8211 An all new design results in a 15 mm shorter rear shock which is 100 g lighter compared to the previous generation while the rear wheel travel is set at 293 mm Inside the shock is a Computational Fluid Dynamics CFD optimised main piston for improved initial comfort which provides hold up in all conditions Different sized holes in the shims allow them to open more easily which reduces the overall stress of the oil flow Complete with low friction SKF seals and a revised linkage system consistent damping comfort and traction are guaranteed with rebound and both high and low speed compression now adjustable by hand

Swingarm 8211 The new hollow die cast aluminium swingarm is manufactured from a single piece of aluminium using an improved die cast production process for optimal stiffness and a 190 g weight reduction over previous versions In order to optimise and match the flex characteristics from the new frame a new 22 mm rear axle is fitted Additionally the chain guard and chain slider have been completely redesigned for improved durability and are less prone to hooking on external objects

Functional Bodywork 8211 Clean Swedish inspired design and ergonomics are tailored to allow riders to perform at their best for extended periods of time Adapted after countless hours of testing the contact points and surfaces in the rider triangle have been repositioned for 2023 to improve comfort on the motorcycle A new flatter seat offers unrestricted movement with a high grip cover ensuring riders stay firmly in place under hard acceleration

Airbox 8211 Designed with precisely positioned inlet ducts aimed at reducing drag and air flow deformation the airbox ensures unrestricted airflow with maximum filter protection The TWIN AIR filter is easily accessed without tools by simply removing the left side panel for easy maintenance Offering further performance customisation the FC 450 is delivered with an additional airbox cover that can be changed without the use of any tools for a sharper throttle response according to rider preference or track conditions

Hydraulic Clutch 8211 The high performance Brembo hydraulic 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 cold or hot conditions as well as over time Countless hours of race focused testing have proven the high quality Italian made Brembo hydraulic systems 8217 exceptional reliability

Hydraulic Brakes 8211 The highest level of quality is guaranteed with class leading Brembo callipers made from single pieces of aluminium for strength at the lowest possible weight

Cooling System 8211 Manufactured from high strength aluminium the radiators are designed using Computational Fluid Dynamics CFD to channel air in the most effective way
A large centre tube channels coolant through the frame to reduce pressure at this point in the system for a more consistent flow while a new internal thermostat further enhances reliability

Fuel Tank 8211 A new and bigger 7 2 litre fuel tank integrates neatly into the revised bodywork Due to the new fuel pump design and position the tank is emptied further for increased running times For improved safety the external fuel line is specifically routed to make it less exposed and susceptible to damage

Map Select Switch 8211 A redesigned and intuitive handlebar mounted map select switch allows riders to activate launch and traction control enable the new Quickshift functionality and allows riders to toggle between two engine maps The easy to operate map select switch allows racers to quickly alter and set up the engine characteristics on a race by race basis dependent on track conditions and rider preference

Quickshift 8211 The new 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 open without the use of the clutch 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 second gear upwards

Traction Control 8211 Traction control on the FC 450 is engaged by a button marked 8216 TC 8217 on the map select switch 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 to ensure maximum traction This is a distinct advantage in wet or muddy conditions

Launch Control 8211 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 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 a gear change is made the launch control will deactivate automatically Additionally the Quickshift function is deactivated while launch control mode is engaged

Mapping 8211 For personalised power delivery the FC 450 has two built in engine maps as standard Map 1 offers linear predictable power while Map 2 is more aggressive for a sharper throttle response and more explosive power output

EMS 8211 The new Engine Management System EMS is designed to be smaller and lighter while being faster at processing data It incorporates a new Rollover Sensor ROS which cuts the ignition and shuts off the engine for safety in the event of a severe crash adding another level of safety to Husqvarna Motorcycles 8217 new generation motocross line up

Hour Meter 8211 A new hour meter comes with an integrated fuel level indicator which is visible on the FI status LED indicating to the rider when the fuel level is becoming low

Start Stop Switch 8211 The new combined start stop switch is located on the right side of the handlebar for easy thumb operated use Not only simplifying the starting and stopping of the engine the removal of a designated stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall

Electric Start 8211 Along with the benefit of an easy electric starting system a lightweight Li Ion 2 0 Ah battery is fitted to the FC 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
