Husaberg FE 501 (2000-2001): A Pure Enduro Machine That Defies Compromise

Introduction

The early 2000s marked a pivotal era for enduro motorcycles, and the Husaberg FE 501 (2000-2001) stands as a testament to the Swedish-Austrian brand’s obsession with off-road purity. Designed during a transitional period when four-stroke technology began dominating the dirt, this 501cc beast carved its niche with a blend of raw power, minimalist design, and race-bred agility. Having spent days wrestling this machine through rocky trails, sandy washes, and even a makeshift supermoto circuit, I can confidently say the FE 501 is a time capsule of enduro ethos—flaws and all. Let’s dissect why this bike remains a cult favorite among vintage off-road enthusiasts.

Engine Performance: Unapologetic Power Meets Mechanical Soul

At the heart of the FE 501 lies a 501cc liquid-cooled single-cylinder four-stroke engine, producing 52 hp (38 kW). This isn’t just a number—it’s an experience. The engine’s 95 mm bore and 70.1 mm stroke deliver a visceral, punchy character that thrives in mid-range torque.

Carburetion & Throttle Response

The 2000-2001 models retained a carbureted setup (Keihin or Dellorto, depending on configuration), which demands patience in tuning but rewards with an analog rawness missing in modern fuel-injected bikes. Cold starts require finesse—the choke, hidden under the tank, is awkwardly placed but effective once mastered. Once warmed up, the engine barks to life with a throaty growl from its derestricted exhaust, a sound that’s equal parts intimidating and addictive.

On the trail, the power delivery is linear but urgent. Unlike modern dual-sports that cushion their power with electronics, the FE 501’s throttle is a direct wire to adrenaline. It pulls hard from 3,000 RPM, with a surge that demands respect in technical sections. Dyno tests from the era show it matching the KTM 520 EXC in torque, and you feel it—the bike lofting the front wheel in third gear with a mere twitch of the wrist.

Transmission & Gearing

The 6-speed gearbox is a highlight. Shifts are precise, and clutchless upshifts under load are butter-smooth. However, finding neutral can be a frustrating game of “half-clicks,” especially when the engine is hot. The final drive’s 14/48 sprocket combo (typical for enduro setups) balances crawlability with open-trail speed, though riders often swapped to a 15T front for supermoto duty.

Chassis & Handling: A Dance Partner for the Bold

Frame & Weight Distribution

The FE 501’s chrome-molybdenum steel frame is a masterpiece of early-2000s engineering. With a dry weight of 105-113 kg (231-249 lbs), it feels shockingly light when flicked sideways. The wheelbase stretches to 1,490 mm (58.7 inches), providing stability at speed without sacrificing agility.

What’s remarkable is how the frame manages stiffness. Husaberg’s “double-cradle” design offers torsional rigidity for precise cornering, yet flexes enough to absorb square-edge hits. During a high-speed run through a rocky riverbed, the bike tracked straight even as the rear wheel skipped over baby-head rocks—a testament to its balanced chassis geometry.

Suspension: WP’s Golden Era

The WP USD 4860 MA forks and WP PDS 5018 shock are period-correct jewels. The 48mm forks, while soft for aggressive supermoto use (more on that later), shine in their natural habitat: enduro. With 300 mm of travel, they swallow deep ruts and logs without bottoming harshly. The rear PDS (Progressive Damping System) shock eliminates linkage, reducing weight and complexity. It’s plush on small bumps but firms up progressively under big hits—a trait that saved my spine during a misguided cliff descent.

Ergonomics: Tall, Slim, and Commanding

At 930-950 mm (36.6-37.4 inches), the seat height is towering for shorter riders but perfect for stand-up riding. The narrow polyamide subframe and tank design let you grip the bike with your knees effortlessly. After a 50-mile loop, the thinly padded seat becomes a torture device—a reminder that comfort was secondary to weight savings.

Brakes & Wheels: Confidence in the Chaos

Brembo supplied the braking components, and they’re stellar. The 260 mm front disc (with a optional 310 mm supermoto rotor) and 220 mm rear disc offer progressive bite. On loose terrain, the front brake modulates beautifully, avoiding washouts. Swap to street tires, though, and the soft forks protest under heavy braking—a cue to upgrade springs if supermoto antics are your priority.

The spoke wheels (21" front, 18" rear) are lightweight and durable. I tested both the knobby-shod enduro setup and the optional 17" supermoto wheels. The latter transforms the FE 501 into a hooligan machine, dragging knees through roundabouts with absurd ease.

Competition: How the FE 501 Stood Its Ground

In 2000-2001, the FE 501 faced fierce rivals:

1. KTM 520 EXC: The Austrian cousin shared the FE 501’s engine DNA but added electric start and a broader parts network. The KTM felt slightly heavier but more refined.
2. Husqvarna TE 570: Another Swedish contender, the TE 570 offered similar power but with a reputation for bulletproof reliability.
3. Yamaha WR426F: The WR was more trail-friendly, with a smoother powerband but less peak horsepower.

The Husaberg’s advantages?
- Weight: At 105-113 kg, it undercut the KTM 520 EXC by ~5 kg.
- Suspension: WP’s closed-cartridge forks were ahead of the curve.
- Character: Raw, unbridled personality that appealed to purists.

Its Achilles’ heel? Carburetion quirks and limited dealer support. While rivals embraced electric start, Husaberg’s kickstarter-only 2000 model (updated to electric/kick in 2001) tested patience in muddy races.

Maintenance: Keeping the Legend Alive

Key Considerations:

1. Air Filter Access: The frame-integrated airbox (filter under the tank) is ingenious but requires frequent cleaning. Upgrade to a twin-air filter for better airflow.
2. Oil Changes: The 1.2L oil capacity demands strict intervals—every 10-15 hours. Use a quality 10W-50 synthetic.
3. Carb Tuning: Swap the stock needle for a JD Jet Kit to smooth out low-RPM hesitation.
4. Suspension Refresh: Rebuild WP components every 100 hours. Consider stiffer springs for supermoto use.
5. Electrical Gremlins: The 2001’s electric starter is reliable but keep the kickstarter as a backup.

MOTOPARTS.store Recommendations:

• High-Performance Clutch Kit: Reduce slippage during hard enduro climbs.
• Skid Plates: Protect the fragile frame rails from rock strikes.
• LED Headlight Upgrade: For night trail rides.
• Retrofit Kickstarter Kit: Essential for 2001 models lacking one.
