2021 Husqvarna FE 350 and FE 501 enduro range

Husqvarna has announced the launch of their 2021 FE lineup. The FE 350 and FE 501 4-stroke range includes offroad only as well as dual-sport models that offer a generous supply of torque, high-quality components, selectable engine mapping and traction control. In dual-sport trim, the FE 350s and FE 501s offer great versatility and rider experience on and off the road.

Following a big revamp of the FE lineup last year, Husqvarna is announcing some additional tweaks for the 2021 models including graphics refinements and updated transmission shift lockers for the FE 501’s powerplant.

Husqvarna 2021 FE models will begin arriving at US dealers this summer. Details for the new FE range will be available on the Husqvarna site starting June 22nd. For more information from Husqvarna, read below:

2021 FE 350 / FE 350s Highlights

The 350 possesses a 450-rivalling power-to-weight ratio while keeping the light and agile feel of a 250. Underlining the great performance of the range, Rockstar Energy Husqvarna Factory Racing’s Billy Bolt recently secured the 2020 FIM SuperEnduro World Championship title aboard his FE 350.

Engine

The 350 cc engine is designed to be powerful, light and compact. The engine weighs only 61.5 lbs (27.9 kg) while retaining its torquey nature, making the 350 engine accessible for both professionals and amateurs.

  • Engine design → light and compact for optimized mass-centralization
  • Powerful engine → accessible for all skill levels

Cylinder and piston

Both FE 350 and FE 350s feature a forged bridged-box-type piston made by CP. The cylinder and piston are professionally engineered from high-strength aluminum.

  • Optimal compression ratio and engine performance
  • Forged box-type → low weight, low oscillating mass

Crankshaft

The plain big end bearing features two force-fitted bearing shells ensuring maximum reliability and durability, guaranteeing long service intervals of 135 hours.

  • Plain big end bearing with force-fitted bearing shells → 135-hour service interval

Counter balancer shaft

In order to counteract the rotational force of the crankshaft and reduce vibration, both models feature a multifunctional counter balancer shaft that also drives the water pump and timing chain.

  • Multifunctional counter balancer shaft → reduced vibrations, compact design

Crankcases

The crankcases are engineered to house the shaft arrangements at the ideal center of gravity and now also integrate the oil supply to the main bearing. 

  • Crankcases → light and compact, mass-centralization
  • High-pressure die-cast production process → reduced weight, while maintaining strength

Gearbox

The 6-speed gearbox from Pankl Racing Systems uses specific wide-range off-road type gearing. Additionally, a gear sensor allows the EMS to tailor a specific engine character suited for each gear.

  • Pankl 6-speed gearbox → off-road specific ratios
  • No-dirt gear lever → prevents dirt build up for perfect control

DDS clutch

The DDS (Dampened Diaphragm Steel) clutch includes a single diaphragm steel pressure plate instead of traditional coil springs making the clutch pull very light while also integrating a damping system for better traction and durability. The MAGURA hydraulic system ensures perfect action in all conditions.

  • DDS clutch → compact with better action and improved durability
  • MAGURA hydraulic system → perfect clutch action

FE 501 / FE 501s Highlights

The FE 501 and FE 501s feature class leading technology and premium components as standard. Combined with traction control, WP suspension and the progressive rear linkage, the FE 501s is the most powerful dual-sport in Husqvarna Motorcycles’ range.

Engine

Weighing only 64.8 lbs (29.4 kg), the engines are not only light and compact but suited specifically for off-road and dual-sport type riding. Features include a standard electric start, 6 speed wide ratio gearbox and, on the off-road only FE 501, electronic rider aids such as traction control and the handlebar map select switch.

  • Engine → lightweight and compact
  • Class leading electronics for the off-road only FE 501 → traction control, map select

Cylinder and piston

The lightweight aluminum cylinder features a 95 mm bore and a lightweight Konig forged bridge-box-type piston perfectly matched to the high-compression combustion chamber. This combination produces very little oscillating mass reducing vibration and increasing rider comfort. 

  • Lightweight aluminum cylinder → 95 mm bore
  • Lightweight forged bridged-box-type piston by Konig → high performance, reduced oscillating masses

Crankshaft

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

  • Plain big end bearing and force-fitted bearing shells → increased durability and service intervals

Counter balancer shaft

In order to counteract the rotational force of the crankshaft and reduce vibration, the engines use a multifunctional counter balancer shaft, which also drives the water pump.

  • 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, centralizing masses for a lightweight handling feel.

  • Mass-centralization for lightweight handling
  • High-pressure die-cast production process → thin walls for optimized weight, while maintaining strength

Gearbox

The lightweight 6-speed gearbox ensures 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

The DDS (Dampened Diaphragm Steel) clutch includes a single diaphragm steel pressure plate instead of traditional coil springs making the clutch pull very light while the integrated damping system improves traction and durability. The clutch basket is a single-piece CNC machined steel component that contributes to the compact design of the engine. 

  • DDS clutch → compact with better action and improved durability
  • MAGURA hydraulic system → perfect clutch action

  1. The fuel tanks are to small. I would insist the dealer install a tank with a reasonable fuel capacity at no extra charge. If a bike is street legal a buyer has a reasonable expectation that the damn thing can at least go far enough to make it to the next gas pump.

  2. I’m confused. The big end main bearings are a service interval? The interval is about 125 hours?? Did I understand that right? So, this interval, if correct, is increased from some lesser value? Ummm, no thanks.

    • All the enduro and MX manufacturers provide service intervals on pistons, rings, bearings, etc. for har/racing use. It’s often pretty short, maybe 100 hours. The oil change interval is much shorter than that. That said these bikes are very durable when used for more “normal” riding, since most of us are not Billy Bolt or anywhere close.

  3. Most of the excitement appears to be in the motors of these machines. Even a casual glance through the material above shows that. So, excepting for the DDS clutch, I’m thing the motors are shared with the 2020 KTM product line? I’m struggling to learn the difference, besides bold new graphics.

    • You are correct in recognizing the similarities. There are minor differences, mostly in the frames and suspension. Husqvarna is well known for a polymer sub-frame, and KTM is known for using a non-linkage rear shock. I’m sure there are more small tweaks between the two.
