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 a 8.50-litre fuel tank, offers a seat height of 950 mm and spans a 1482 mm wheelbase. That's roughly 90.4 kg lighter than the average enduro / off-road motorcycle in our database. The full 2021 Husqvarna FE 501 spec sheet below covers every technical detail, from suspension travel to tyre sizes.

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 950 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 8.50-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.

Brake disc and pad wear

Braking up front comes from Single disc. Magura. Wave disk. - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The FE 501's suspension runs WP XPLOR-USD, Ø 48 mm at the front. The rear uses WP XACT Monoshock 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 Central double-cradle-type 25CrMo4 steel, 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, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. 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 a FE 501's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). 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.
