FE 501S

01. Titanic power

Engine

The most powerful engine in the Husqvarna Motorcycles FEs line-up, the 510.9 cc power plant is more advanced than ever while only weighing 64.8 lbs. Delivering colossal performance in all conditions, the FE 501s power is controlled with a lightweight 6-speed transmission and DDS (Dampened Diaphragm Steel) clutch.

Cylinder head

The SOHC cylinder head is incredibly compact and lightweight using a short profile with the camshaft located as close to the center of gravity as possible, significantly improving handling and agility. The lightweight valves are actauted via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response. 40 mm titanium intake valves, 33 mm steel exhaust valves and low-friction DLC coating on the rocker arm and shorter low-friction chain guides offer the optimum efficiency and reliability.

Crankcase

The crankcases are designed to house the shaft arrangements and internals of the engine in the best possible position, centralizing masses for a lightweight handling feel. High-pressure die cast production processes result in a thin but reliable wall thickness and keeping weight to a minimum.

Cylinder and piston

The lightweight aluminium cylinder features a 95 mm bore and a lightweight Konig forged bridge-box-type piston. This is perfectly matched to the high compression combustion chamber, producing very little oscillating mass. The high compression ratio of 12.75:1 reduces vibration and engine knocking, further increasing rider control and comfort.

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 grey powder coated frame features standard frame protectors, providing extra durability.

Integrated cooling and radiators

The radiators are expertly crafted using high-strength aluminium with CFD (computational fluid dynamics) to channel air through the radiators more efficiently. The cooling system is intelligently integrated into the frame, eliminating the need for additional hoses. The large centre tube running through the frame reduces pressure at this point, allowing for a consistent coolant flow. Additionally, the radiators are mounted close to the centre of gravity for improved handling agility. A radiator fan is fitted as standard to keep engine temperatures low in all conditions.

Composite carbon fibre subframe

The carbon composite subframe is unique to Husqvarna Motorcycles and showcases advanced production technology and innovation. Using 70% polyamide and 30% carbon fibre, the 2-piece subframe has a total weight of just over 2.2 lb. With the help of computational dynamics, specific rigidity was engineered into the light and robust subframe, delivering outstanding handling and rider comfort.

Exhaust

The exhaust system is expertly designed to deliver class-leading performance at the lowest possible weight. The header pipe is designed and manufactured in two pieces, to be as compact as possible. It also features a joining position, which allows it to be removed without having to take out the rear shock. Further innovation allows for a shorter, more compact silencer without increasing noise levels. The component is crafted from lightweight aluminum and is stylishly finished off in a coating that highlights its premium quality.

03. Precise handling

WP XPLOR front fork

The WP XPLOR 48 front fork is designed specifically for off-road riding. Its open cartridge layout has a spring in each leg with split damping functions. Compression damping is in the left leg and rebound damping is in the right. Adjustment is via easy-to-access clickers (30 clicks) on the top of each fork leg. The standard preload adjusters allow for easier adjustment without the use of tools. The fork's mid-valve piston delivers consistent damping, while the setting allows the fork to operate higher in the stroke for exceptional rider feedback and bottoming resistance.

WP XACT rear shock

The WP XACT shock provides advanced damping characteristics to the range. The compact and lightweight shock features a pressure balance inside, ensuring consistent damping and superior rider comfort. Using the same linkage progression found in the Husqvarna Motocross range, the rear end sits low for improved control in extreme enduro conditions. The fully adjustable component delivers 300 mm rear wheel travel, as well as unrivalled traction, feeling and energy absorption.

Hydraulic brakes

The highest level of quality is guaranteed with the new BRAKTEC braking system, offering the highest level of braking performance while being specifically tailored for enduro riding and delivering a sensitive and modulated feel. GSK wave discs (260 mm disc front and 220 mm rear) complete the high-quality braking package for complete confidence.

Bodywork

The FE 501s features a bodywork which clearly showcases Husqvarna Motorcycles' progressive approach to offroad motorcycles while rugged grey and electric yellow accents provide a distinctive look and stylishly adorn the Swedish inspired design. 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. Premium technology

TOOL-LESS AIR FILTER ACCESS

The airbox is designed with precisely positioned inlet ducts aimed at preventing air deformation and ensuring maximum airflow and filter protection. The air filter is easily accessed, without tools, by removing the left side panel. Easy maintenance is guaranteed by the Twin Air filter and filter cage design that features a simple fail proof mounting system for safe and accurate filter installation.

Throttle body

The FE 501s features a 42 mm Keihin throttle body optimized for throttle response. The injector is positioned to ensure the most efficient flow into the combustion chamber while the throttle cable is mounted directly without a throttle linkage. This provides an immediate throttle response and improved feel.

Electric start and wiring harness

The FE 501s comes standard with an electric starter. The system uses a compact and lightweight Li-Ion battery which is 2.2 lbs lighter than a conventional battery. With several years of experience of developing and perfecting electric starting, the proven reliability on the Husqvarna enduro range is second to none, ensuring a quick and seamless start in any condition. Additionally, the wiring harness concentrates all needed electrical components into a common area below the seat for easy accessibility.

Hydraulic clutch

The new high quality BRAKTEC clutch system guarantees even wear, reliable and near maintenance-free operation as well as 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.
