• 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.

Faster and wiser

• ENGINE: The FC 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 behavior from the whole chassis. Weighing just 59.9 lb (27.2 kg), the 350 cc 4-stroke engine is tilted two degrees backwards and is 8 mm shorter in height to further centralize mass.
• CYLINDER HEAD: Fully redesigned for 2023, 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 optimize gas flow for strong, usable power access the rev-range, all the way up to the 13,400 rpm limit. Revised valve timings work in perfect harmony with the redesigned camshaft which now features a new bearing bridge designed to increase stiffness and improve serviceability.
• CYLINDER AND PISTON: A large 88 mm bore and 57.5 mm stroke cylinder is professionally engineered from high-strength aluminum for maximum reliability, and houses the high performance forged bridged-box-type piston from CP. For 2023, the compression ratio is increased to 14.6:1 for improved torque and peak power. Engine responsiveness is further improved thanks to optimized valve guides and valve shaft diameters precisely engineered using computational fluid dynamics (CFD).

For improved on-track agility and stability through ruts, the FC 350 is fitted with a 110/90-19 rear tire while a 80/100-21 front tire ensures optimal grip on a variety of riding surfaces.
• 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 center of gravity and ensuring impressive power while keeping noise as low as possible. A black coating highlights the premium quality of the silencer.
• COOLING SYSTEM: Manufactured from high-strength aluminum, the radiators are designed using computational fluid dynamics (CFD) to channel air through them in the most effective way. A large center 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 1.9 gal (7.2 liter) 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.

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 behavior of the chassis. With optimized 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 ALUMINUM SUBFRAME: Made from 60% polyamide and 40% aluminum, the new two-piece subframe for 2023 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 aluminum for significantly improved reliability. The upper section of the subframe is made from injection-molded polyamide to enable specific flex characteristics and ensure a lightweight construction.
• 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 customized 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: The 48 mm WP XACT forks feature a closed cartridge system and a capsulated, adjustable air spring. Together with a pressurized oil chamber, the forks deliver a smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with the mid-valve damping system, the forks provide precise feedback to the rider. To ensure maximum forward momentum after heavy landings, a hydrostop applies a progressive damping force in the last 40 mm of travel. 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. Additionally, the pump needed to adjust the air spring pressure in the forks is provided with each Heritage machine.
• WP XACT SHOCK ABSORBER: The 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) optimized 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 optimize and match the flex characteristics of the chassis, a 22 mm rear axle is utilized. Additionally, the chain slider is exceptionally durable while the chain guide is manufactured with a rounded profile to ensure it is less prone to catching on external objects.

Technologically advanced

• 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 riders to quickly alter and set up the engine characteristics on a race by race basis dependent on track conditions and rider preference.
• 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 FC 350 Heritage model is engaged by pressing the button marked 'TC' on the Map Select Switch and functions by analyzing 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 Quickshifter buttons simultaneously. Both symbols will start flashing to indicate that 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 Quickshifter function is deactivated when Launch Control is engaged.
• MAPPING: For personalized power delivery, the FC 350 Heritage machine has two built-in engine maps as standard. Map 1 (white) offers linear, predictable power, while Map 2 (green) is more aggressive for a sharper throttle response and a more explosive power output.
• 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 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: As 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.
