The new FX 350 engine is designed to deliver maximum performance. For 2023, the repositioning of all major engine components and shaft arrangements enhances overall handling with the design improving anti-squat behaviour from the whole chassis. The engine is tilted two degrees backwards and is 8 mm shorter in height to further centralise mass. Weighing just 59.9 lb (27.2 kilograms), the new 350cc 4-stroke engine produces a higher and more usable power output. |
|
Fully redesigned for 2023, the DOHC cylinder head offers improved durability and serviceability, with Diamond Like Carbon (DLC) coated finger followers to guarantee minimal friction and optimal performance. These actuate large titanium valves, 36.3 mm for the intake and 29.1 mm for the exhaust, which optimise gas flow for strong, usable power across the rev-range, all the way up to the 13,400 rpm limit. Revised valve timings work in perfect harmony with the redesigned camshaft which now features a new bearing bridge designed to increase stiffness and improve serviceability. |
|
An 88 mm bore and 57.5 mm stroke cylinder is professionally engineered from high-strength aluminium for maximum reliability and houses the high performance forged bridged-box-type piston from CP. For 2023, the compression ratio is increased to 14.6:1 for improved torque and peak power. |
|
At the heart of the high-output, high-revving FX 350 engine is the crankshaft which features a plain big end bearing rotating on two force-fitted bearing shells for maximum reliability and guarantees long service intervals of 90 hours. |
|
Designed for optimised mass centralisation, the FX 350 crankcases house all internal components in the perfect position to achieve the ideal centre of gravity. Manufactured using a high-pressure die cast production process, the result is a thin, exceptionally strong wall thickness at the lowest possible weight. |
|
The FX 350 features a revised (DS) Diaphragm Steel clutch. Engineered from a single piece of CNC-machined steel, the redesigned clutch basket accommodates the new gearbox and allows the use of thin steel liners, which contribute to the compact design of the engine. |
|
Produced by PANKL RACING SYSTEMS, the 6-speed gearbox is designed to be extremely light and durable with optimised gear ratios |
|
The proven chromium molybdenum steel frame is refined for 2023 to reposition rotational masses inside the engine which together with a new shock mounting position, significantly improves anti-squat behaviour of the chassis. With optimised wall thickness in high-stress areas improving reliability, the frame continues to offer advanced geometries and flex characteristics aimed at providing unparalleled rider feedback, energy absorption, and exceptional straight-line stability. The frame is finished off in a premium white powder coating with redesigned standard frame protectors offering superior protection, durability, and grip in any condition. Additionally, the inclusion of forged brackets on the lower frame rails allows for easy installation of the standard skid plate. |

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 - 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. |
|
The 48 mm split air WP XACT forks now offer improved bottoming resistance thanks to a new hydrostop, which applies a progressive damping force in the last 40 mm of travel for even greater comfort. The WP forks are designed with a capsulated, adjustable air spring and pressurized oil chamber for smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with a midvalve damping system, the forks provide precise feedback to the rider. The settings are easily adjusted via the single air pressure pre-load valve, as well as through easy access click adjusters for compression and rebound. For improved durability, new fork protection rings prevent dirt intrusion. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard. |
|
The all-new WP XACT rear shock is 100 g lighter and 15 mm shorter than its predecessor yet the travel remains unchanged. Inside the shock is a Computational Fluid Dynamics (CFD) optimised main piston for improved initial comfort which provides strong 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. |
|
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 catching on external objects. |
|
The bodywork clearly showcases Husqvarna Motorcycles' progressive approach to offroad motorcycles while the Swedish heritage-inspired blue and yellow graphics create a distinctive look. The ergonomics are tailored to deliver exceptional comfort and control, enabling riders to perform at their best for extended periods of time. Adapted after countless hours of testing, the contact points have been repositioned for 2023 and together with a flatter seat profile, riders can move freely on the motorcycle for total control at all times. |
|
Easy access to the TWIN AIR filter is possible without tools, for quicker cleaning and easier maintenance. Precision inlet ducts maximise airflow and offer increased levels of filter protection. |
|
The high-performance BRAKTEC 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, Braktec hydraulic systems' exceptional reliability. |
|
The highest level of quality is guaranteed with class-leading BRAKTEC callipers made from single pieces of aluminium for strength at the lowest possible weight. Together with a 260 mm front and a 220 mm rear disc removing dirt efficiently, superior stopping power and braking confidence is guaranteed in all conditions. |
|
Developed between Husqvarna Motorcycles and leading handlebar manufacturer, ProTaper, the exclusive bend offers superior comfort, class-leading strength, and fatigue resistance at the lowest possible weight. Fitted to the handlebar as standard are our open handguards for added protection in the demanding offroad environments. On top sits the black ProTaper handlebar pad adding style and safety. |
|
ODI lock-on grips feature an innovative integrated throttle mechanism and a glue-free installation. The throttle assembly offers easy free-play adjustment with the option to fit alternative cams for a personalised throttle action. |
|
All-new, CFD-designed footrests offer a 26.8% larger contact area to ensure better control of the machine while being less susceptible to hooking on deep ruts, take-offs when scrubbing, or trackside barriers. This was achieved by a new, narrower mounting design in the frame layout, which also helps reduce overall weight. |
|
CNC-machined hubs and high-strength alloy rims by EXCEL are finished in striking black. They feature laser engraved logos and are fitted with a DUNLOP GEOMAX MX33 tyre on the front and DUNLOP GEOMAX AT81 tyre on the rear which ensure progressive cornering and superior traction on a variety of terrain. |
|
The exhaust system on the FX 350 features a flow-designed resonance chamber, which plays a vital role in delivering class-leading performance. Manufactured in two pieces and designed to be as compact as possible, the header pipe allows for the system to be removed without removing the rear shock. The silencer has a short and efficient design, moving weight closer to the centre of gravity and ensuring impressive power while keeping noise as low as possible. A black coating highlights its premium quality. |
|
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. |
|
A new 2.24 gal (8.5 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. |
|
A redesigned and intuitive handlebar-mounted map select switch allows riders to activate launch and traction control, 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. | |
|
For personalised power delivery, the FX 350 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. | |
|
The Hitachi-Astemo (formerly Keihin) EMS is designed to be small, lightweight and fast at processing data. It integrates traction control for perfect starts, selectable engine maps via the switch on the handlebar, as well as launch control. | |

|
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. |
|
|
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. | |
|
Traction control on the FX 350 is engaged by a button marked 'TC' 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. | |
|
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. |
