2025 Husqvarna FX350 Totalmotorcycle.com Features and Benefits
Faster and wiser
Engine
The FX 350 engine is designed to deliver maximum performance with all major engine components and shaft arrangements positioned to enhance overall handling. Weighing just 59.9 lb (27.2 kg), the 350 cc 4-stroke engine centralises mass and aids the anti-squat behaviour of the whole chassis.
Cylinder head
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. Valve timings work in perfect harmony with the camshaft, which features a bearing bridge design for stiffness and easy serviceability.
Cylinder and piston
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. The compression ratio is 14.6:1 for exceptional torque and peak power.
Crankshaft
At the heart of the high-output, high-revving FX 350 engine is the crankshaft. This features a plain big end bearing rotating on two force-fitted bearing shells for maximum reliability and guarantees long service intervals of 90 hours.
Crankcases
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.
DS clutch
The FX 350 features a diaphragm steel (DS) clutch. Engineered from a single piece of CNC-machined steel, the clutch basket allows the use of thin steel liners that contribute to the compact design of the engine.
Gearbox
Produced by Pankl Racing Systems, the new 6-speed gearbox is extremely light and durable and features optimised gear ratios exclusive to the FX 350. Specific engine maps for each gear ensures the best performance possible. Integrated on the shift drum, the Quickshifter can be activated via the Map Select Switch to further aid smooth upshifting.
Ride easier
Frame
For 2025, new engine mounts with cut-outs improve the chassis flex characteristics, reduce weight, and contribute to a confidence inspiring riding experience. The frame is revised by reducing and removing material around the steering head and shock mount, which lowers the weight of the frame by 300 g. Together, these revisions improve cornering and ensure unparalleled rider feedback, energy absorption, and straight-line stability. A premium metallic blue powder coating is applied to the frame with protectors offering superior protection, durability, and grip in all conditions.
Polyamide-reinforced aluminium subframe
Made from 60% polyamide and 40% aluminium, the two-piece subframe ensures exceptional strength and durability at an overall weight of just 3.9 lb (1.8 kg). The lower subframe spars and frame mounts are manufactured from cast aluminium for strength at the lowest possible weight. Injection-molded polyamide is used to construct the upper section of the subframe to enable specific flex characteristics.
Triple clamps
Working in unison with the frame design and suspension set-up, the CNC-machined triple clamps ensure precisely calculated geometry for increased 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.
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 FX 350 provide exceptional comfort. For 2025, the settings are updated to suit the new frame and linkage revisions. 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.
WP XACT rear suspension
Inside the WP XACT rear shock is a Computational Fluid Dynamics (CFD) optimised main piston for superior initial comfort and to provide strong hold-up in all conditions. Updated for 2025, the linkage features new, lower friction seals while a smaller diameter linkage bolt reduces weight. The standard rebound and high and low speed compression settings have been adapted to suit the new frame and can be easily adjusted by hand to create a personalised set-up.
Swingarm
The swingarm is manufactured using a die-cast production process for optimal rigidity. To optimise and match the flex characteristics of the chassis, a 22 mm rear axle is utilised. For 2025, the machining of the swingarm helps to improve the durability of the new chain slider.
Effortless ergonomics
Bodywork
The bodywork has been designed so riders can perform at their very best for extended periods of time. Following countless hours of testing and refinements, the large contact points and surfaces in the rider triangle enhance grip on the machine, which helps to reduce fatigue. New tank shrouds complement the progressive look of the bodywork while a sightly taller and wider seat allows for complete freedom of movement on the motorcycle. A high grip cover ensures riders stay firmly in place under hard acceleration.
Tool-less airbox
A stronger, one-piece airbox design with an optimised air intake reduces air deformation, ensuring an unrestricted flow of air and maximum filter protection. The Twin Air filter is easily accessed without tools, by simply removing the left side panel for easy maintenance.
Hydraulic clutch
The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation, and perfect action in every condition. With this hydraulic system, free 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 exceptional reliability of the high-quality, Italian-made Brembo hydraulic system.
Hydraulic brakes
The highest level of quality is guaranteed as the class leading Brembo brake calipers are made from single-piece aluminium for exceptional strength at the lowest possible weight. Together with a 260 mm front and a 220 mm rear disc, which are designed to prevent mud build-up, superior stopping power and braking confidence is guaranteed in all conditions. For 2025, a new, stronger rear brake pedal offers improved durability for continued braking performance.
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.
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 and trackside barriers. This is achieved by a narrower mounting design in the frame layout, which also helps reduce overall weight.
Master your art
Wheels and tyres
CNC-machined hubs and high-strength alloy rims by D.I.D are finished in striking black. They feature laser engraved logos and are fitted with a Dunlop Geomax MX33 tyre on the front and a Dunlop Geomax AT81 tyre on the rear. This tyre combination ensures progressive cornering and superior traction across a variety of terrain.
Exhaust system
The exhaust system on the FX 350 features a flow-designed resonance chamber, which plays a vital role in delivering maximum 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. For 2025, this cross country model features the same silencer as found on the motocross models for improved throttle response while also being considerably quieter.
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 2.24 gallon (8.5 litre) fuel tank integrates neatly with the ergonomic bodywork and features an updated rubber cushion beneath it to protect against wear from the frame. The one-piece fuel pump and integrated filter allows the tank to be emptied further to offer an extended running time. For improved durability, the external fuel line is specifically routed to make it less exposed and susceptible to damage.
Technologically advanced
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.
Quickshift
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 and false neutrals, the function is only active from second gear upwards.
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 FX 350 starts with the ease of pressing a button thanks to electric start. A lightweight Li-Ion 2.0 Ah battery is fitted, giving the convenience of electric starting while keeping overall weight to a minimum.
Engine management system
The 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 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 getting low.
Start/stop switch
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.
Technologically advanced
Traction Control
Traction Control on the FX 350 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.
