The most powerful engine in the Husqvarna Motorcycles FE line-up, the 510.4 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.
A new compact design has resulted in the SOHC cylinder head being 15 mm lower and 500 g lighter. This has also moved the camshaft closer to the centre of gravity, improving handling, while shorter valve timing improves bottom end performance and responsiveness. An improved cam surface and with new rocker arms actuating four lightweight valves are shorter, with 40 mm titanium intake valves and 33 mm steel exhaust valves. Low-friction DLC coating on the rocker arm and shorter low-friction chain guides also provide optimised efficiency and reliability.
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.
The new chrome-moly steel frame is expertly crafted using laser-cut, robot-welded, hydro-formed tubes, ensuring the highest level of precision and quality. While retaining the advanced geometry of its predecessor, it features an increase in longitudinal and torsional rigidity, for improved rider feedback, better energy absorption and increased stability. The cylinder head mountings are made of forged aluminium, further improving handling and comfort. The premium blue powder coated frame features standard frame protectors, providing extra durability.
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. For 2020, the standard preload adjusters allow for easier adjustment without the use of tools. The fork’s updated mid-valve piston delivers more consistent damping, while a new setting allows the fork to operate higher in the stroke for improved rider feedback and bottoming resistance.
Featuring a new main piston and updated base setting to match the new frame and front end, the WP XACT shock provides advanced damping characteristics to the new 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 now sits lower, 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.
