Rolling into 2022 all Enduro bikes feature premium Michelin Enduro tyres. To cope with the added traction the suspension settings on the fork and shock have been revised improving rider feedback. New Braktec hydraulics offer superior braking power and perfect modulation of the clutch under all conditions. Underlining the update, our Enduro's wear new rugged grey colour and electric yellow accents.
01. TITANIC POWER
The most powerful engine in the Husqvarna Motorcycles FE line-up, the 510.9 cc power plant is more advanced than ever while only weighing 29.4 kg. Delivering colossal performance in all conditions, the FE 501 can be controlled using a number of advanced electronic rider aids such as traction control while a handlebar-mounted map select switch alters power delivery to suit terrain and skill levels.
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 actuated 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, low-friction DLC coating on the rocker arm and low-friction chain guides offer the optimum efficiency and reliability.
CYLINDER & 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.
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.
02. STATE OF THE ART CHASSIS
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.
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 1 kg. With the help of computational dynamics, specific rigidity was engineered into the light and robust subframe, delivering outstanding handling and rider comfort.
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. The joining position allows it to be removed without having to take out the rear shock. Further innovation allows for a short, compact silencer without increasing noise levels. The component is crafted from lightweight aluminium and is stylishly finished off in a black coating that highlights its premium quality.
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.
03. PRECISE HANDLING
WP XPLOR FRONT FORK
The WP XPLOR 48 front fork is designed specifically for enduro riding. Its open cartridge layout has a spring in each leg with split damping functions. Compression damping in the left leg and rebound damping 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. A new oil bypass in the outer tube reduces friction for a smoother, consistent travel through the stroke and a revised cartridge joint offers added damping performance.
WP XACT REAR SHOCK
The WP XACT shock provides advanced damping characteristics to the range. New valve seals with reduced hardness offer improved shock feedback. 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.
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 disks (260 mm disc front and 220 mm rear) complete the high-quality braking package for complete confidence.
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.
The FE 501 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
MAP SWITCH & TRACTION CONTROL
Designed for easy operation, the standard map switch selects between 2 EFI maps and activates the traction control feature. The TC (Traction Control) feature improves control on slick terrain. Traction Control can be switched on or off from the map switch. It 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 FE 501 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 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 501 comes standard with an electric starter. The system uses a compact and lightweight Li-Ion battery which is 1 kg 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.
