FC 250 2024

Hailed as the highest performing 250 cc 4-stroke motocross machine on the market, the FC 250 is equipped with multiple, performance-focused technical upgrades to maintain its place at the head of the field. New for 2024, striking white, yellow, and grey graphics are applied using in-mold technology for an outstanding and long-lasting finish while revised suspension settings further improve overall handling. Housed inside a lightweight chromium molybdenum frame, the compact, powerful, and versatile engine features a Pankl gearbox for smooth gear changes with a Quickshifter further aiding upshifts, especially under heavy load.

ENGINE
Engineered to ensure class-leading performance and handling characteristics, all major engine components and shaft arrangements are carefully positioned closer to the centre of gravity to reduce the effects of rotational inertia. Tilted two degrees backwards to further centralise mass, the 250 cc 4-stroke engine is also 60 g lighter than the previous generation, tipping the scales at just over 26 kg. The FC 250 engine remains remarkably powerful with an increased power output and impressive torque to suit riders of all abilities.

DOHC CYLINDER HEAD
Featuring finger followers treated with a Diamond-like Carbon (DLC) coating, the DOHC cylinder head is engineered for high-level performance and improved performance and durability. The titanium intake valves remain at 32.5 mm while the exhaust valves increase in size to 27.5 mm – a direct result of the bore/stroke ratio, which in turn optimises gas flow. These revisions allow the FC 250 to rev freely and produce strong and efficient power throughout the rev range up to its 14,000 rpm limit.

CYLINDER AND PISTON
An 81 mm bore houses a forged bridged-box-type piston made by CP, which weighs just 150 g. High strength aluminium is used to manufacture both the cylinder and piston, with both components professionally engineered for outstanding performance and reliability. The stroke has been adapted to 48.5 mm to match the resized cylinder, boosting the compression ratio to 14.5:1 and adding further torque and peak performance to the FC 250.

CRANKCASES
The FC 250 crankcases are designed to optimise mass centralisation by housing all internal components in the ideal position to achieve the perfect 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 FC 250 features a revised Diaphragm Steel (DS) clutch. Engineered from a single piece of CNC-machined steel, the redesigned clutch basket accommodates the gearbox and allows the use of thin steel liners, which contribute to the compact design of the engine. Identical to the one used in the stronger FC 450, it is adapted perfectly to the transmission ratio.

GEARBOX
Produced by Pankl Racing Systems, the 5-speed gearbox is designed to be extremely light and durable while featuring optimised and proven motocross-specific gear ratios (24:72). A redesign of the shift shaft reduces the operating forces required for gear changes. Integrated into the shift drum, a quickshift sensor can be activated by pressing the QS marked button on the Map Select Switch to further aid seamless upshifting.

LIGHTWEIGHT FRAME
The proven chromium molybdenum steel frame remains for 2024. The shock mounting, which is no longer connected to the main tube, significantly improves the 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 metallic blue 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 skid plate, which is available as a technical accessory.

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 1.8 kg. The lower subframe spars and frame mounts are manufactured from cast aluminium for significantly improved reliability. The upper section of the subframe is made from injection-moulded polyamide to enable specific flex characteristics and ensure a lightweight construction.

CNC MACHINED TRIPLE CLAMPS
Matching the 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 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
The 48 mm split air forks now offer improved bottoming resistance thanks to a 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, fork protection rings prevent dirt intrusion. Additionally, the air pump needed to adjust the fork’s air pressure is provided as standard.

WP XACT SHOCK ABSORBER
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 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 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 frame, a 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
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 were repositioned in 2023 to improve comfort on the motorcycle. A flatter seat offers unrestricted movement with a high grip cover ensuring riders stay firmly in place under hard acceleration.

AIRBOX
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 250 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
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’ exceptional reliability.

HYDRAULIC BRAKES
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. Together with a redesigned 260 mm front and a 220 mm rear disc which offer improved dirt removal, superior stopping power and braking confidence is guaranteed 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.

ODI GRIPS
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.

FOOTRESTS
The 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 narrower mounting design in the frame layout, which also helps reduce overall weight.

WHEELS AND TYRES
Assembled with CNC-machined hubs, strong spokes, and black-anodised alloy rims by D.I.D, the wheels of the FC 250 are fitted with DUNLOP GEOMAX MX33 Motocross tyres which feature a proven block-within-a-block design for more progressive cornering and superior grip. For improved on-track agility and stability through ruts, the FC 250 is fitted with a 110/90-19 rear tyre while a 80/100-21 front tyre ensures optimal grip on a variety of riding surfaces.

EXHAUST SYSTEM
Designed from lightweight aluminium, the exhaust system on the FC 250 features a flow-designed resonance chamber that is integrated into the header pipe. The silencer has a short and compact design, delivering impressive power output while keeping decibels as low as possible.

COOLING SYSTEM
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 an internal thermostat further enhances reliability.

FUEL TANK
A 7.2 litre fuel tank integrates neatly into the revised bodywork. Due to the 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
A redesigned and intuitive handlebar-mounted map select switch allows riders to activate launch and traction control, enable the 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
The 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
Traction control on the FC 250 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.

LAUNCH CONTROL
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
For personalised power delivery, the FC 250 has two built-in engine maps as standard. Map 1 offers linear, predictable power, while Map 2 is more aggressive for sharper throttle response and more explosive power output.

EMS
The engine management system (EMS) is designed to be smaller and lighter while being faster at processing data. It incorporates a 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’ motocross line-up.

HOUR METER
An 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
The 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
The convenience of a lightweight starter motor and compact battery set-up means starting the motor, or recovering from a stall effortlessly, is as simple as a push of a button.
