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

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.
My 501 gets almost 170 miles out of the stock tank
nice bike
Your tank is larger than 2.16 gallons or you are getting 80mpg. Or you are wrong or lying.
It’s a race ready bike with a plate. It’s meant to be nimble and fast, that’s what it is designed for. If you’re wanting a dual sport, get a DRZ. If you want change this bike into a longer range bike, buy a bigger tank. Cush hub. Crash protection. Better lighting. But don’t complain that the Ferrari doesn’t have enough room to store groceries from the store.
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.
Oil change interval. Silly. And it was 135 not 125
lol
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.
OK, yup. Got it. I saw that when servicing my own KTM 690. Thank You!
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.
Just rode my brand new FE350s on a 15 mile freeway ride to the beach. My hands were buzzing from the vibration of going 75 miles an hour when I got there.
Why so much vibration?
Hey Nick. These bikes are designed to be no-compromise enduros with only the bare minimum equipment to make them street legal. Riding on the highway at 75 mph is probably where they feel least at home. Most people buy this style of bike strictly for dirt riding using short sections of asphalt to link up trails. You can try vibration damping devices for the bars, changing the gearing or slow down to smooth it out, if you must ride highway.
