Description
Husqvarna FE 501s Features

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 actuated via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.

Crankcases
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.

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.

Integrated Cooling and Radiators
The radiators are expertly crafted using high-strength aluminum 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 center tube running through the frame reduces pressure at this point, allowing for a consistent coolant flow.

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.

>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.

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.

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.

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.
