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 mounting brackets for the newly designed skid plate, which is available as a technical accessory.
Together with the new shock mounting, which is no longer connected to the main tube, the anti-squat behaviour of the chassis has been significantly improved. Additionally, the wall thickness of the frame has been optimised to achieve improved reliability and specific rigidity in high stress areas such as the steering head and the shock mount. Parallel frame mounts (same position on left and right sides) improve chassis flex characteristics, while straight line stability remains unrivalled.
Another highlight of the new frame design is that the footrest mounting positions have been moved inwards, resulting in less susceptibility to catching in deep ruts or when scrubbing jumps. The overall size of the all-new footrests has been increased using state-of-the-art Computational Fluid Dynamics (CFD). The new one-piece steering head seal allows easier mounting in case of replacement or service and offers improved reliability.
The frame is finished off in a premium metallic blue powder coating. The standard frame protectors feature a new and improved surface for superior protection, durability, and excellent grip in all riding conditions.
- Specifically engineered longitudinal rigidity → exceptional rider feedback, energy absorption and stability
- New shock mounting design → significantly improved anti-squat of chassis
- Varying frame wall thickness for specific rigidity and improved reliability in high-stress areas (e.g., steering head, shock mount)
- New parallel frame mounts (same position on left and right side) for improved flex characteristics
- Footrest mounting position moved inwards for reduced risk of catching in deep ruts or when scrubbing jumps
- New, service friendly one-piece steering head seal → easier mounting, improved reliability
- Durable powder coated finish with standard frame protectors
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 to guarantee strength and reliability. The upper subframe is made from injection-moulded polyamide, enabling specific flex characteristics and allowing a lightweight construction.
- New polyamide/aluminium hybrid construction
- Lower subframe spars and frame mounts made from cast aluminium→ extremely robust and reliable with no weld joints
- Upper subframe made from injection-moulded polyamide → specific rigidity and flex benefit handling and comfort
Swingarm
The new hollow die-cast aluminium swingarm is designed to offer optimal stiffness and reliability at the lowest possible weight. Engineered to ensure precise rigidity, an improved casting process reduces weight by approximately 190 g. In order to optimise and match the new chassis flex characteristics, a new 22 mm rear axle is fitted.
Additionally, the chain guard and chain slider have been completely redesigned, resulting in improved durability and are less susceptible to catching on external objects. This new design helps reduce dirt build up around the swingarm and chain guard, especially in extremely muddy conditions.
- Chain adjustment markings are easily visible from above to make for simpler adjustment.
- New die-cast swingarm → topology-optimised for optimal rigidity
- Improved casting process for reduced weight → 190 g less than previous generation
- New 22mm rear axle optimised to match chassis flex characteristics
- Newly designed chain guard and chain slider
- Transitions aligned with swingarm surface, spring-steel mounted for improved durability
- Overall, less susceptible to catching on external objects
WP XACT front forks with AER technology
The 48 mm split air forks feature 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. A new 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. Redesigned dust seals prevent dirt intrusion into the fork legs.
Settings are easily adjusted via a single air-pressure preload valve, as well as via easy access click adjusters for compression and rebound. Additionally, the air pump needed to adjust the air pressure is provided as standard.
- WP XACT front forks → 48 mm air type with split damping function
- Midvalve damping system → exceptional damping and consistent performance
- Capsulated air spring and pressurized oil chamber → progressive and consistent damping
- New hydrostop in fork legs → improved bottoming resistance and reduced rebound
- More progressive damping in last 40 mm of travel (total 305 mm) → previous generation hydrostop was only effective in final 10 mm of travel
- Reduced rebound → fork stays lower on initial acceleration after hard landings
- Easy access clicker dials → fast and simple setting changes by hand
- Redesigned dust seals → increased protection against dirt intrusion
CNC-machined triple clamps
Made from high-grade aluminium, the 22 mm offset CNC-machined triple clamps ensure perfect alignment of the fork tubes for increased stability and a smooth action from the WP XACT front forks. The upper triple clamp is stiffer and works in harmony with the front forks to ensure superior handling while the handlebar clamp offers three mounting options for customisable ergonomics.
New handlebar mounts feature a larger clamping area for less handlebar twist in the event of a fall at the same weight as the previous generation. Additionally, they allow for both rubber-damped and fixed mounting of the handlebar to offer customisable handlebar flex.
- Rubber-damped → less vibration, less precise front-end feel (OE)
- Fixed → increased vibration, more precise front-end feel
The front number plate integrates a triple clamp protector which covers the lower triple clamp and protects it from roost damage.
- CNC-machined aluminium with anodised surface → finest quality and reliability
- Perfect clamping and alignment → smooth fork action
- New handlebar mounts → increased clamping area for less handlebar twist at the same weight as the previous generation
- Rubber damping on top clamp → reduced vibration, increased comfort
- Adjustable handlebar position → customisable ergonomics
WP XACT rear shock
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. The shock is matched to a revised linkage system with new geometry to deliver the same progression as before but with the greatest possible traction and absorption. Combined with the new frame geometry, it improves the ground clearance of the linkage and is therefore less susceptible to damage when bottoming out.
The new, Computational Fluid Dynamics (CFD) optimised main piston in the shock improves initial comfort and provides strong hold-up. Differently sized flow holes in the shims allow them to open more easily and reduces the overall stress of the oil flow and pressure on the shims. Reduced weight also means less moving mass, resulting in lower forces on the main piston.
A fully hand-adjustable dual compression control concept allows high and low speed settings to be easily changed by hand. Together with the newly designed rebound adjuster, which is hand or tool adjustable, riders are now able to adjust their shock settings without tools or need the assistance of a mechanic at the racetrack.
In addition to the tool-free setting adjustment possibilities, a new preload adjuster is introduced, which brings increased resistance to dirt intrusion. A new two-piece retainer allows for quick spring changes without disassembling 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.
- New lightweight, compact rear shock design with 15 mm reduced overall length
- 2022 → 470 mm / 2023 → 455 mm | rear wheel travel → 293 mm
- Reduced weight results in less moving mass → 100 g lighter design results in lower forces on bearings
- New CFD-optimised main piston increases initial comfort and guarantees strong hold-up
- Improved ground clearance, lower risk of damage in extreme bottoming-out situations
- New dual compression control allows high and low speed settings to be adjusted by hand
- New rebound adjuster allows for setting changes to be made by hand or tool
- Reworked preload adjuster with increased resistance to dirt intrusion
- Low-friction SKF linkage seals → refined rear shock response for advanced damping characteristics
- Pressure balance inside the shock body → consistent damping
- Two-piece retainer allows for quick spring changes without disassembling the shock
Brembo hydraulic clutch
The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation, and perfect action in all conditions. This means that play is constantly compensated so that the pressure point and function of the clutch remains identical in cold or hot conditions, as well as over time. The high quality, Italian-made Brembo hydraulic system has been developed from countless hours of race-focused testing to ensure exceptional reliability.
- Brembo hydraulic clutch system → perfect action in all conditions and outstanding reliability
Brakes
The highest level of quality is guaranteed with class-leading Brembo calipers and controls. The 260 mm floating front and 220 mm wave rear discs deliver superior stopping power and instil confidence in all conditions.
- Brembo brake calipers and high-performance discs → superior stopping power with greater control and rider confidence
ProTaper handlebar
The ProTaper handlebar is second to none for function and style. Manufactured to exacting standards, the handlebar features class-leading fatigue resistance at a minimal weight. The handlebar bend is designed to increase comfort by not putting additional pressure on the hands of riders.
- ProTaper handlebar → class-leading function and style
- Husqvarna bend → optimal comfort
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.
- Throttle assembly and ODI grips → easily alter throttle progression; easy grip mounting without glue
Footrests
The all-new footrests, designed using Computational Fluid Dynamics (CFD), offer a bigger surface for boot soles while being less susceptible to catching on deep ruts, take-offs when scrubbing, or trackside barriers. The result is better control of the bike in all conditions, which was achieved by a new, narrower mounting concept integrated in the frame design. This also reduces overall weight.
- New die-cast footrests → reduced weight and less susceptible to dirt build-up
- Footrest mount integrated in frame → narrower profile is less likely to hook on deep ruts
Map select switch, traction and launch control
Designed for easy and intuitive operation, the new map select switch comes as standard. It activates traction and launch control, selects between two engine maps (aggressive/smooth), and activates the Quickshift feature on 4-stroke models. Map 1 is the standard map for linear, predictable power, while Map 2 is an aggressive map for a sharper throttle response and a stronger power delivery.
The new Quickshift can be activated or deactivated via the map select switch. It works by interrupting the ignition momentarily and only functions when upshifting between second and fifth gear. A sensor on the shift drum registers the force from the shift lever, which sends a signal to the ECU to temporarily pause the ignition timing. This ensures smooth gear changes, even with the throttle fully open and without the need to use the clutch.
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 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. Additionally, the Quickshift function is deactivated while launch control mode is engaged.
Traction control on 4-stroke models is engaged by a button 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 to ensure maximum traction. This is a distinct advantage in wet or muddy conditions.
- Newly designed handlebar map select switch → alters engine characteristics according to conditions and rider preference
- New Quickshift function → smooth and clutch-free upshifting
- Traction control → optimal traction in all conditions
- Launch control → maximum traction for perfect starts
Start/stop switch
The new combined start/stop switch on the right side of handlebar allows for easy, intuitive starting and stopping 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 traction control switch on the handlebar, as well as the new Quickshift function. Combined with the gear sensor, power delivery is tailored for each gear.
A new Rollover Sensor cuts the ignition in the case of extreme crashes, adding another level of safety to the new generation of Husqvarna motocross machines. Additionally, the new hour meter now comes with an integrated FI status LED and a fuel level indicator.
- Keihin EMS → smaller, lighter, and faster at processing engine data for more efficient engine management
- New Rollover Sensor (ROS) → automatically stops the engine in extreme crashes
- New hour meter with integrated FI status LED and fuel level indicator
- Gear sensor → specific engine maps for each gear
Keihin throttle body
The 4-stroke range feature a 44 mm Keihin throttle body with an injector positioned for optimal flow with the throttle cable mounted directly, without a linkage, for optimal engine response.
The new 39 mm Keihin throttle body on the 2-stroke models feature dual injectors. These are positioned to ensure the most efficient flow into the combustion chamber, with the throttle cable mounted directly to the throttle body for a more immediate response from the engine. Idle is controlled over the throttle valve (not over a bypass system as on Transfer Port Injection) with a new dual injector setup – one low load injector (positioned as on 4-stroke models) and one “top-feed” oriented injector for maximum performance before the throttle valve.
The Keihin throttle bodies provide much better idle control, more stable idle behaviour, and a much-improved fuel/air mixture. The result is more power, more response, and a larger fuel/air mixture operation window in comparison to TPI. Therefore, it is less prone to engine cut-outs or hesitations, and less sensitive to different ambient conditions (e.g. temperature, altitude, humidity).
- 4-stroke throttle body → 44 mm, injector positioned for optimal flow, more immediate throttle response thanks to direct cable mounting
- 2-stroke throttle body → 39 mm with two injectors positioned for optimal flow and more immediate throttle response thanks to direct cable mounting
Exhaust system
Tailored specifically for each model using an innovative 3D design process, the 2-stroke header pipes offer optimal geometry and performance, and ground clearance, meaning they are less susceptible to damage. The 2-stroke mufflers also feature an aluminium mounting bracket and advanced internal construction for excellent noise damping and weight saving.
The 4-stroke exhaust systems are expertly designed to deliver leading performance at the lowest possible weight. The header pipe has been designed and manufactured in two pieces to be as compact as possible, with section one featuring an integrated flow-design resonance chamber for reduced sound and maximum performance. The position of the join in the header pipe allows for easy disassembly without the need to remove the rear shock. Further innovation allows for a short, compact silencer with no increase to noise levels or restrictions in performance. The silencer is crafted from lightweight aluminium and is stylishly finished in a black coating that highlights its premium quality.
- Compact exhausts → lightweight and engineered for maximum performance
- Header pipe mounted directly onto engine mount for improved serviceability
- Header join position → easy removal of exhaust without removing rear shock
Electric start and Li-Ion battery
Along with the benefit of an easy electric starting system, a Li-Ion 2.0 Ah battery is fitted to the full Husqvarna motocross range. The Li-Ion battery weighs approximately 1 kg less than a conventional lead/acid battery, so the convenience of electric starting is delivered while minimising overall weight.
- Electric starter → easy starting when time is critical
- Li-Ion battery → lightweight, 1 kg lighter than a conventional battery
Integrated cooling system and radiators
The radiators are expertly crafted by WP using high-strength aluminium. Computational Fluid Dynamics (CFD) optimisation was used in the design process to channel air through the radiators efficiently to provide optimal cooling in all conditions. The cooling system integrates into the frame, eliminating the need for additional hoses, where a large centre tube ensures a more consistent flow of coolant. A new internal thermostat aids reliability.
Additionally, the radiators are mounted close to the centre of gravity for improved handling agility.
- Integrated cooling → maximum efficiency in minimum space
- New bayonet closure radiator caps
- WP radiators → efficient for optimal cooling
- Large central tube → consistent coolant flow
Fuel tank
New 7.2 litre polythene fuel tanks use a reliable threaded filler cap and a new, one-piece fuel pump with integrated filter. This improves fuel supply and allows the tank to be emptied further at low fuel levels, allowing for extended running times. The external fuel line is specifically positioned to make it less exposed and susceptible to damage.
- New 7.2 litre polythene fuel tanks → larger capacity for extended running times
- New one-piece fuel pump and filter for improved fuel supply → tank can be emptied further at low fuel levels
- External fuel line routing → less exposed and susceptible to damage
Airbox and tool-less air filter access
Computational Fluid Dynamics (CFD) were used to optimise the airbox design with precisely positioned inlet ducts preventing air deformation and ensuring maximum airflow and filter protection. Replacing or inspecting of the air filter is quick and easy, without tools, by removing the left side panel. A Twin Air filter element is fitted to a filter cage designed with a simple fail-proof mounting system for safe and accurate filter installation.
- CFD optimised airbox → improved air flow and maximised filter protection
