Engine

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.

Cylinder

The DOHC cylinder head offers improved durability and serviceability, with diamond-like carbon (DLC) coated finger followers that 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. Valve timings work in perfect harmony with the camshaft, which features a bearing bridge design for stiffness and easy serviceability.

Cylinder and piston

A large 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. The compression ratio is 14.6:1 for exceptional torque and peak power. Engine response is strong thanks to optimised valve guides and valve shaft diameters that are precisely engineered using computational fluid dynamics (CFD).

Crankcase

Designed for optimised mass centralisation, the 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.

Crankshaft

At the centre of the high-output, high-revving engine is a crankshaft featuring a plain big end bearing rotating on two force-fitted bearing shells. Ensuring maximum reliability and durability, the crankshaft offers long service intervals of 90 hours.

DS clutch

The FX 350 Heritage model features a durable diaphragm steel (DS) clutch. Engineered from a single piece of CNC-machined steel, the clutch basket uses thin steel plates, which contribute to the compact design of the engine.

Gearbox

Produced by Pankl Racing Systems, the 6-speed gearbox is designed to be extremely light and durable while featuring optimised and proven motocross-specific gear ratios (24:72). Integrated into the shift drum, a Quickshifter sensor can be activated by pressing the QS marked button on the Map Select Switch to further aid smooth upshifting.

ride easier

Frame

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.

CNC machined triple clamps

Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps ensure precisely calculated geometry for assured stability. Handlebar flex can be customised with the 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.

Polyamide-reinforced aluminium subframe

WP XACT front suspension

Rigorously tested by WP's research and development department, the 48 mm WP XACT closed cartridge spring forks fitted to the TX 300 Heritage model provide exceptional comfort. Inside the forks, mid-valve pistons optimise oil flow and prevent foaming for consistent and predictable damping at all times. A hydrostop, active in the final 68 mm of travel, reduces the impact of harsh and high-speed landings for continued straight line stability and forward momentum. Both the compression and rebound settings can be quickly adjusted by hand using the easy access clickers. Additionally, the pump needed to adjust the air spring pressure in the forks is provided with each Heritage machine.

WP XACT rear suspension

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.

Swingarm

The swingarm is manufactured using a die-cast production process for optimal rigidity. To match the flex characteristics of the chassis, a 22 mm rear axle is utilised. Additionally, the swingarm is designed to enhance the durability of the chain glider while the chain guide features a rounded profile that makes it less prone to catching on external objects.

effortless ergonomics

Bodywork

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.

Tool-less airbox

A strong, one-piece airbox with optimised air intake tracts ensure an unrestricted flow of air for maximum power. The Twin Air filter is easily accessed without tools, by simply removing the left side panel for easy maintenance.

Hydraulic clutch

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.

Hydraulic brakes

The highest level of performance is guaranteed thanks to the class leading Brembo calipers and controls. Together with GSK wave discs (260 mm disc front and 220 mm rear), which are designed to prevent mud from building up, superior stopping power and braking confidence is assured in all conditions.

Protaper handlebar

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 grips

ODI lock-on grips feature an innovative, integrated throttle mechanism and are installed without using glue. The throttle assembly offers easy free-play adjustment with the option to fit alternative cams for a personalised throttle action.

Footrests

The CFD-designed footrests are extra wide to ensure better control of the machine while at the same time they are less susceptible to catching on deep ruts, take-offs when scrubbing, and trackside barriers. This was achieved by the narrow mounting design in the frame layout.

Wheels and tyres

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.

Cooling system

Manufactured from high-strength aluminium, the radiators are designed using computational fluid dynamics (CFD) to channel air through them in the most effective way. A large centre tube through the frame reduces pressure at this point in the system for a consistent coolant flow while an internal thermostat further enhances reliability.

Fuel tank

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.

Exhaust system

The exhaust system on the FC 350 Heritage model 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 the premium quality of the silencer.

technology advanced

Quickshifter

The Quickshifter function can be activated or deactivated via the Map Select Switch and works by interrupting the ignition for a fraction of a second when upshifting. A sensor on the shift drum registers the force from the shift lever, sends a signal to the ECU, and ensures smooth gear changes, even when the throttle is fully open. To prevent unintended shifts, the function is only active from second gear upwards.

Traction Control

Traction Control on the FX 350 Heritage model is engaged by pressing 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.

Mapping

By using the Map Select Switch, the engine characteristics can be tailored to modify the power delivery according to rider preference, conditions, and terrain. It has two settings that can be safely toggled between while riding, by simply pressing a button on the handlebar-mounted Map Select Switch. Map 1 (white) is the standard option, that delivers linear, predictable power, while map 2 (green) is more aggressive with improved throttle response and sharper, explosive power output.

E-Start

The combined engine 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, but the removal of an additional stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall.

Map Select Switch

The intuitive handlebar-mounted Map Select Switch allows riders to activate Launch and Traction Control, enable the Quickshifter, 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.

Engine management system

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.

Hour meter

The engine management system (EMS) is designed to be small, light, and fast at processing data. It incorporates a rollover sensor (ROS) which cuts the ignition and shuts off the engine in the event of a severe crash for an additional layer of safety.

Start/stop switch

The hour meter comes with an integrated fuel level indicator, which is visible on the FI status LED, and warns the rider when the fuel level is becoming low.
