FE 450 Heritage 2025

01. Progressive performance

Engine

When it comes to versatility, the DOHC 350 cc engine is second to none. By sharing much of its architecture with the 250 cc engine, the FE 350 delivers a fine balance between 450-rivaling power and lightweight 250 handling.

Cylinder head

The SOHC cylinder head is incredibly compact and lightweight with the camshaft positioned as close to the centre of gravity as possible. A durable, fine-punched cam chain and Diamond-Like Carbon (DLC) coated rocker arm offer optimal efficiency and reliability with a single oil spray jet providing effective cooling. Valve timings are optimised for maximum torque and a smooth power delivery.

Cylinder and piston

The lightweight aluminium cylinder is an engineering masterpiece with a 95 mm bore and a stroke of 63.40 mm. Inside, the forged CP bridged-box-type piston features anodised annular grooves for added durability and extended service intervals. The compression ratio is 12.75:1.

Crankcases

Designed to be low in weight without sacrificing strength or reliability, the crankcases are made using a high-pressure die cast production process to create a thin-wall design. To centralise engine mass, the shaft arrangements are precisely positioned to harness rotating masses at the ideal centre of gravity.

Throttle body

The FE 450 Heritage model features a 42 mm Keihin throttle body optimised for throttle response. The injector is positioned to ensure the most efficient flow into the combustion chamber with the throttle cable mounted directly without a linkage for an enhanced response.

Exhaust

The exhaust system is expertly designed to deliver class-leading performance at the lowest possible weight with the header pipe manufactured in two pieces. This design allows the header pipe to be taken off of the machine without needing to remove the rear shock. Further innovation allows for a short, compact silencer without increasing sound levels. The silencer is crafted from lightweight aluminium and stylishly finished with a black coating to highlight its premium quality.

02. State of the art chassis

Frame

The chromium molybdenum steel frame is expertly crafted using laser-cut, robot-welded, hydro-formed tubes, ensuring the highest level of precision and quality. The specifically crafted geometry utilises advanced longitudinal and torsional flex characteristics, for unparalleled rider feedback, energy absorption and exceptional straight-line stability. The cylinder head mountings are made of forged aluminium, improving handling and comfort. The premium white powder coated frame features standard frame protectors, providing extra durability.

Hybrid 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 maximum reliability. The upper section of the subframe is made from injection-moulded polyamide to enable specific flex characteristics and ensure a lightweight construction.

Swingarm

The swingarm is manufactured using a die-cast production process for optimal rigidity. To match the flex characteristics of the chassis, a 22 mm rear axle is utilised. Additionally, the swingarm is designed to enhance the durability of the chain glider while the chain guide features a rounded profile that makes it less prone to catching on external objects.

Bodywork

The bodywork is designed to allow riders to perform at their best for extended periods of time. A flat seat profile offers unrestricted movement. Above the side panels, recessed pockets allow for the machine to be lifted and moved, which is particularly beneficial for those competing in extreme enduro events.

Radiators

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 channels coolant through the frame to reduce pressure at this point in the system for a more consistent flow. An internal thermostat enhances reliability while the radiator cap features a bayonet style closure for a secure fitment.

Fueltank

An 8.0 litre fuel tank integrates neatly with the ergonomic bodywork and features a robust rubber cushion beneath it to hold the tank in place and protect the frame from wear. The one-piece fuel pump design and integrated filter allows the tank to be emptied further, which is particularly beneficial during longer events. For durability, the external fuel line is specifically routed to make it less exposed and susceptible to damage.

Triple clamps

The black-anodized, CNC-machined triple clamps offer premium quality as standard. They have a carefully calculated 22 mm offset and are expertly crafted using superior techniques and materials for the highest levels of quality and reliability. The handlebar clamp has a large contact surface with the ProTaper bars to help prevent twisting in the event of a crash and offers two mounting options for customisable ergonomics.

03. Innovative advantage

WP XACT front forks

Designed and developed for the rigours of enduro riding, the WP XACT Closed Cartridge spring forks offer consistent performance thanks to an innovative internal design that optimises oil flow and prevents oil from foaming. The hydrostop, effective in the last 68 mm of travel, is highly advantageous when landing heavily as it helps to maintain forward momentum. Additionally, riders can alter the compression and rebound settings quickly and easily using the tool-free adjusters found at the top and bottom of each fork leg.

WP XACT rear shock

The lightweight WP XACT rear shock offers 300 mm of travel. With the rebound and both high and low speed compression adjustable by hand, setting changes can be achieved quickly and easily without tools. Complete with a CFD optimised shock piston and low friction seals, consistent damping, comfort, and traction is guaranteed.

Hydraulic brakes

The highest level of performance is guaranteed thanks to the class leading Brembo calipers and controls. Together with GSK wave discs (260 mm disc front and 220 mm rear), which are designed to prevent mud from building up, superior stopping power and braking confidence is assured in all conditions.

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 the function of the clutch, remain identical in cold or hot conditions, as well as over time. Countless hours of testing have proven the reliability of the high-quality, Italian-made Brembo hydraulic system.

Wheels and tyres

Black high-strength alloy rims by EXCEL are coupled to CNC machined hubs using lightweight spokes and silver anodised aluminium nipples. Fitted to the wheels are Michelin Enduro tyres which offer superior grip on a wide variety of terrain.

Handlebar

The FE 350 features a bodywork which clearly showcases Husqvarna Motorcycles' progressive approach to offroad motorcycles while the Swedish heritage-inspired blue and yellow graphics create a distinctive look. The ergonomics are specifically tailored to deliver great comfort and control. As a result of extensive testing, the slim contact points make shifting between riding positions easier and allow the rider to flow with movement. The flat seat profile, together with the seat cover texture, deliver superior comfort and control in all conditions.

04. Technology advanced

LED headlight

The LED headlight provides a remarkably bright light output for excellent visibility at night and is particularly effective when riding through dense woodland. A clever mounting design sees the LED lighting unit fitted inside the headlight mask using a quick-release system that allows it to be replaced quickly and easily if damaged.

Map Select Switch

Designed for easy operation, the Map Select Switch allows riders to easily choose between two EFI maps, activates Traction Control, and engages the Quickshifter. Traction Control can be switched on or off via the Map Select Switch and functions by analysing throttle input from the rider and the rate at which the engine RPM increases. If the RPM increases too quickly, the EMS registers a loss of grip and reduces the amount of power to the rear wheel, ensuring maximum traction. The Quickshifter can also be engaged using the same Map Select Switch and offers seamless upshifts under heavy load.

Quickshift

The Quickshifter can be activated or deactivated via the Map Select Switch. By interrupting the ignition for a fraction of a second, this allows upshifting while the throttle is fully open without the use of the clutch. The Quickshifter is only active from second gear upwards.

Electric start

Taken from the motocross range, 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, but 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.

Footrest

Using state-of-the-art computational fluid dynamics, the large footrests are designed for maximum control and to prevent mud from building up. Additionally, the mounting position brings them inwards, which makes them less susceptible to catching on the ground through deep ruts.
