FC 250 HERITAGE

01. Faster and wiser

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 250cc 4-stroke engine is also 60 g lighter for 2023, 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 further refined for 2023 with multiple revisions to improve 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 new 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

A new 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 new 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 new 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 new Quickshift sensor can be activated by pressing the QS marked button on the map select switch to further aid seamless upshifting.

02. Ride easier

Lightweight frame

The proven chromium molybdenum steel frame is refined for 2023. A new 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 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 skid plate, which is available as a technical accessory.

Polyamide-reinforced aluminium subframe

Made from 60% polyamide and 40% aluminium, the new two-piece subframe for 2023 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 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.

WP XACT front suspension

The 48 mm split air 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.

WP XACT shock absorber

Inside the WP XACT rear shock is a Computational Fluid Dynamics (CFD) optimised main piston for exceptional comfort with the overall design of the shock providing strong hold-up in all conditions. The linkage system features low-friction seals for unrestricted suspension performance with a lightweight bolt utilised to save weight. Rebound and high and low speed compression settings can be easily adjusted by hand to simplify any set-up changes.

Swingarm

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 hooking on external objects.

03. Effortless ergonomics

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 have been repositioned for 2023 to improve comfort on the motorcycle. A flat seat offers unrestricted movement with a high grip, ribbed seat 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 and bar pad

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. 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 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

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.

Wheels and tyres

Assembled with CNC-machined hubs, strong spokes, and black-anodised alloy rims by EXCEL, 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 a new internal thermostat further enhances reliability.

Fuel tank

A new and bigger 7.2 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.

05. Technologically advanced

Map select switch

A redesigned and intuitive handlebar-mounted map select switch allows riders to activate launch and traction control, enable the new 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 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.

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

Hour meter

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.

Start/stop switch

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.

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.
