With titles in the MX2 World Championship and AMA Supercross series to its name, the FC 250 is recognised as a highly competitive machine. Designed for motocross racing at every level, each component is selected for its performance and durability. Riders can take advantage of cutting-edge technology to gain an edge over their rivals with Traction Control, a Quickshifter, and a choice of engine maps elevating the on-track experience. Its compact and powerful DOHC engine plays a vital role in how the FC 250 handles, as its placement within the chromium molybdenum frame centralises mass to enhance agility. Completing the build, quality parts from WP, D.I.D, Dunlop, ProTaper, Twin Air, and ODI highlight the premium specification of the FC 250. |
Engine
Engineered to ensure class-leading performance and handling characteristics, all major engine components and shaft arrangements are carefully positioned closer to the center of gravity to reduce the effects of rotational inertia. The 250 cc 4-stroke engine is also considerably light and tips the scales at just over 57 lb (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 unrivalled durability. The titanium intake valves are 32.5 mm while the exhaust valves are 27.5 mm for optimised gas flow. The FC 250 revs freely, and produces strong and efficient power throughout the rev range up to its 14,000 rpm limit. |
Cylinder and piston
The 81 mm cylinder 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 is 48.5 mm to match the resized cylinder, which creates a compression ratio of 14.5:1 for exceptional torque and peak performance.
|
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.
|
DDS clutch
The FC 250 features a highly reliable diaphragm steel (DS) clutch. Engineered from a single piece of CNC-machined steel, the clutch basket allows the use of thin steel liners, which contribute to the compact overall design of the engine. Underlining just how strong and durable the clutch is, the same components are used inside the much more powerful FC 450 engine. |
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.

CNC machined triple clampsWorking 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. |
|
WP XACT front suspensionRigorously tested by the WP research and development department, the 48 mm WP XACT closed cartridge spring forks fitted to the FC 250 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 40 mm of travel, reduces the impact of harsh and high-speed landings to maintain forward momentum. Both compression and rebound settings can be quickly adjusted by hand using the easily accessible clickers located on top of each fork leg. |
|
SwingarmThe swingarm is manufactured using a die-cast production process and designed with a calculated level of rigidity. To further complement and optimise the flex characteristics of the chassis, a 22 mm rear wheel axle is utilised. A durable chain slider is neatly integrated into the swingarm, ensuring uninterrupted forward momentum through deeply rutted corners. |

Map select switch

|
|
|
Traction ControlTraction Control on the FC 250 is engaged by pressing the 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 ControlWith 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. |
|
MappingFor personalised power delivery, the FC 250 has two built-in engine maps as standard. Map 1 (white) offers linear, predictable power, while map 2 (green) is more aggressive for sharper throttle response and more explosive power output. |
|
EMSThe 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 security to the Husqvarna Motorcycles' new generation motocross line-up. |
|
Hour meterA 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 switchThe 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 startAs with all 4-strokes in the Husqvarna motocross range, the FC 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. |
