2021 Husqvarna FE 501 Overview
Husqvarna FE 501 is an enduro / off-road motorcycle, displacing 510.4 cc. Power comes from a Single cylinder, four-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 12.7:1.. Bore and stroke come in at 95 x 72 mm. On the performance side, it delivers 45 hp of peak power and Nm @ rpm of torque. On the road, the 2021 FE 501 tips the scales at 108.4 kg, carries an 8.5-litre fuel tank, offers a seat height of 970 mm and spans a 1482±10 mm wheelbase. The full 2021 Husqvarna FE 501 spec sheet below covers every technical detail, from suspension travel to tyre sizes.

- With 510 cc, the FE 501 has the joint 541st largest engine displacement of 1434 bikes in the Enduro / Off-Road category, 5% above the category average of 486 cc.
- Narrowing the field to the 471 models within five model years of it, the seat height of 970 mm is taller than that of 462 of the other 470.
Versus the 2019 model
The figures we track are unchanged from the 2019 model: displacement and seat height all match.
2021 FE 501 - Pros & Cons
Strengths
-
⚡
Strong power output: With 45 hp and Nm @ rpm of torque on tap, the FE 501 is no slouch for its class.
-
🔧
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
Considerations
-
📏
Tall seat height: At 970 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
-
⛽
Modest fuel capacity: Range between stops is limited by the 8.5-litre tank - plan fuel stops accordingly on longer routes.
-
⚙️
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.
Wear Points & Servicing Notes
Cooling system servicing
FE 501's Liquid cooling system, continuous circulation of cooling liquid with water pump setup is low-maintenance provided the coolant interval is kept - old, acidic coolant is the main cause of long-term corrosion in the water passages.
Fuelling & injector care
The Keihin electronic fuel injection and 42mm throttle body on the FE 501 needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.
Valve clearance checks
With Single Overhead Cams (SOHC) valve gear, the FE 501 needs periodic clearance checks; caught early they're a cheap adjustment, left unchecked they accelerate valve seat wear.
Suspension condition on used examples
The FE 501's suspension runs WP-USD Xplor 48 with preload adjuster at the front. The rear uses WP shock absorber with linkage. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The FE 501 uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.
Frame & chassis check
Built around a Frame design 25CrMo4 steel central-tube, the FE 501's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.
Low-speed handling
108.4 kg keeps the FE 501 easy to move around in tight spaces, car parks and on the stand alike.
FE 501 - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2021 Husqvarna FE 501 with its 510.4 cc enduro / off-road, cover the fundamentals: service book and oil change history, drivetrain wear, and any sign of oil weeping around the casings. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 5 years old, this enduro / off-road is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Cold-starting it yourself tells you a lot - a healthy FE 501 should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects the FE 501's 510.4 cc single cylinder, four-stroke like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). With a 12.7:1. compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Fuel system care
Fuel injection on the FE 501 needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
Valve clearance service
Valve clearances are easy to overlook on a used FE 501 since a bike out of spec doesn't always feel obviously wrong - but the wear it causes is real. Ask the seller for documentation before assuming it's been done.
