Husqvarna FE 501

The FE 501 houses the most powerful engine in the Husqvarna enduro range. With large moving components, vibration is kept to a minimum through a counter balancer shaft while a standard electric starter ensures easy starting in all conditions. High quality finishes and premium components ensure the FE 501 meets the highest levels of quality and craftsmanship.

ENGINE Combining low weight with a compact design, the FE 450 and FE 501 engines feature the latest technology available offering unequalled performance, ride-ability and reliability. Additionally, both engines are suited specifically for enduro type riding with a standard electric start, 6 speed wide ratio gearbox and an array of electronic rider aids. Updated engines – lightweight, compact & powerful Class leading electronics – traction control, map select, Keihin EFI

MAP SWITCH & TRACTION CONTROL The Husqvarna Enduro 4-stroke model range features a standard mounted handlebar map switch and an advanced traction control feature. The system is able to analyse the throttle input from the rider and the rate at which RPM increases in the engine. If the RPM increases too fast, the ECU will register a loss of grip and reduce the amount of power to the rear wheel to ensure maximum traction in all conditions. Traction control system for maximum traction and control Standard map switch for adjustable engine characteristics

possible weight. The camshaft actuates four lightweight valves (titanium intake Ø=40 mm 32,6 g, steel exhaust Ø=33 mm 42,6 g) through a robust rocker arm system. SOHC – compact engine design

CYLINDER AND PISTON The lightweight aluminium cylinder features a 95 mm bore housing a lightweight Konig bridge-box-type piston. This combination produces very little oscillating mass significantly reducing vibration and increasing rider comfort. The compression ratio is 11.8:1 for both models. Lightweight aluminium cylinder – 95 mm bore Lightweight forged bridged-box-type piston – high performance, reduced oscillating masses

CRANKSHAFT A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 135 hours. Plain big end bearing & force-fitted bearing shells – increased durability & service intervals

COUNTER BALANCER SHAFT In order to counteract the rotational force of the crankshaft and reduce vibration, both engines use multifunctional counter balancer shafts that also drive the water pumps. Multifunctional counter balancer shaft – reduced vibrations, compact design

CRANKCASES The crankcases are designed to house the shaft arrangements and internals of the engine in the best possible position, centralising masses for a lightweight handling feel. High-pressure die cast production processes result in a thin but reliable wall thickness and keep weight to a minimum. Design – mass-centralisation, lightweight handling High pressure die cast production process – thin walls for reduced weight, while maintaining strength

GEARBOX The lightweight 6-speed gearboxes ensure smooth and precise shifting thanks to a low friction coating on the shifting fork. The gear lever features a design that prevents dirt build-up and keeps the lever tip in its original position even in the toughest conditions while a gear sensor allows for specific engine maps in each gear. 6-speed gearbox – lightweight Fork coating – smooth and precise shifting Gear sensor – specific engine maps for each gear

DDS CLUTCH Both engines feature DDS (Dampened Diaphragm Steel) clutches. The exclusive characteristics of this system include a single diaphragm steel pressure plate instead of traditional coil springs making the clutch pull very light while the integrated damping system guarantees optimal traction and durability. The clutch baskets are single-piece CNC machined steel components that allow the use of thin steel liners and contribute to the compact design of the engines. The Magura hydraulic systems ensure perfect modulation in all conditions. DDS clutch – compact with better modulation and maximum durability Magura hydraulic system – perfect clutch modulation
