Husaberg FE 650 E (2004–2008): The Uncompromising Enduro Beast

Introduction

The Husaberg FE 650 E isn’t just a motorcycle—it’s a statement. Produced from 2004 to 2008, this Swedish-engineered enduro machine carved its niche as one of the most powerful single-cylinder dirt bikes ever built. With a cult following and a reputation for adrenaline-inducing performance, the FE 650 E straddles the line between raw power and refined engineering. But does it hold up as a rideable machine today? Let’s dive into what makes this bike tick—and why it still turns heads in the trails.

Engine Performance: The Heart of a Titan

At the core of the FE 650 E lies a liquid-cooled, 644 cc single-cylinder four-stroke engine. With a bore and stroke of 100 mm x 82 mm (3.9 x 3.2 inches) and a compression ratio of 12.2:1, this isn’t an engine that whispers. It roars.

Power Delivery:
The Keihin FCR 41mm carburetor (TPS-equipped in later models) ensures crisp throttle response. Unlike modern fuel-injected bikes, the FE 650 E demands a rider’s intuition—blip the throttle just right, and you’re rewarded with a surge of torque that feels endless. The power builds linearly, but don’t be fooled: this bike will hit 160 km/h (99 mph) with ease, making it a rare breed that’s as comfortable on open roads as it is in rocky ravines.

Starting Rituals:
The dual electric/kick starter system is a nod to practicality. While the electric starter was occasionally finicky in early models (2004–2005), later iterations improved reliability. Still, the kickstarter is there for purists—or for when the battery inevitably dies after a long day of hard riding.

Vibration:
At lower RPMs, the engine feels surprisingly smooth. But push past 100 km/h (62 mph), and vibrations seep into the handlebars and pegs. It’s not a dealbreaker, but it reminds you that this isn’t a pavement-focused machine.

Handling and Suspension: Lightweight Agility Meets WP Wizardry

Chassis:
The 25CrMo4 steel frame is a masterpiece of minimalist design. Weighing just 109–110 kg (240–243 lbs) dry, the FE 650 E feels more like a 450 cc bike in motion. The wheelbase stretches 1,490 mm (58.7 inches), providing stability at speed without sacrificing flickability in tight singletrack.

Suspension Setup:
- Front: WP USD 4860 MA forks with 295 mm (11.6 inches) of travel.
- Rear: WP PDS 5018 monoshock with 320 mm (12.6 inches) of travel.

The suspension is plush yet progressive. Whether you’re hammering through whoops or navigating technical climbs, the WP components absorb impacts without wallowing. Adjustability is limited compared to modern setups, but the stock tuning works brilliantly for riders weighing 70–90 kg (154–198 lbs).

Brakes:
Brembo’s single-disc setup (260 mm front / 220 mm rear) offers ample stopping power. The front two-piston caliper lacks initial bite but rewards modulation—critical when descending slippery trails.

On and Off-Road Performance: Where the FE 650 E Shines

Off-Road Dominance:
This is where the Husaberg earns its stripes. The 380 mm (15-inch) ground clearance laughs at rocks and logs, while the 21-inch front/18-inch rear spoked wheels (90/90-21 and 140/80-18 tires) claw through mud and sand. The engine’s low-end grunt lets you tractor up hills in third gear, and the 6-speed transmission ratios are perfectly spaced for technical terrain.

On-Road Manners:
The FE 650 E is street-legal in many regions, but it’s no commuter. The seat height—930–950 mm (36.6–37.4 inches)—is daunting for shorter riders, and the narrow seat becomes punishing after an hour. Still, for connecting trails or blasting down backroads, it’s a riot.

Fuel Efficiency:
Expect 10–12 km/l (23–28 mpg) off-road and 15–18 km/l (35–42 mpg) on-road. The 9–10.5L (2.4–2.8 gal) tank limits range, but that’s typical for the class.

Ergonomics and Design: Quirks and Charms

Love-It-or-Hate-It Styling:
The yellow-and-blue color scheme screams ’00s Euro flair. The semi-transparent tank is practical for checking fuel levels, but the reversed fuel tap (hidden markings) and buried choke lever are head-scratchers.

Rider Triangle:
The bars are narrow by today’s standards, and the footpegs sit high for aggressive standing riding. Taller riders might crave more legroom, but the setup encourages an active riding style.

Competition: How Does the FE 650 E Stack Up?

KTM 525 EXC (2003–2007):
KTM’s 510 cc rival is lighter and more refined, with better reliability. However, the Husaberg’s engine delivers a harder punch, appealing to riders who prioritize raw power over polish.

Honda XR650L:
The Honda is bulletproof but heavier (144 kg / 317 lbs) and air-cooled. It’s a better choice for reliability-focused adventurers, but it can’t match the FE 650 E’s performance in technical terrain.

Husqvarna TE 610 (2004–2010):
Similar power and weight, but the Husky’s six-speed gearbox isn’t as smooth. The Husaberg’s WP suspension also outclasses the Husqvarna’s Marzocchi/Sachs combo.

Verdict:
The FE 650 E is for riders who value character over convenience. It’s less reliable than Japanese bikes but offers a visceral experience that’s hard to replicate.

Maintenance: Keeping the Beast Alive

Key Considerations:
1. Oil Changes: Use SAE 10W-50 full synthetic every 15–20 hours. The trochoit oil pump is robust, but neglect leads to premature wear.
2. Valve Adjustments: Check every 30 hours. Intake/exhaust valves should be set to 0.12 mm (0.0047 in) when cold.
3. Water Pump: Early models suffer seal leaks. Upgrade to a aftermarket kit (available at MOTOPARTS.store) for durability.
4. Crankshaft: 2003–2004 models had machining issues. Inspect for primary engine noise—a rumbling sound signals imminent bearing failure.
5. Clutch: The hydraulic system is reliable, but slipping the clutch excessively in technical terrain causes “scrunch.” Replace plates with high-friction aftermarket options.

Upgrades We Recommend:
- Radiator Guards: Protect the single radiator from trail debris.
- Aftermarket Exhaust: Unlock hidden power and shed weight.
- Modern Grips and Levers: Improve comfort and control.

Conclusion: A Legend Worth Preserving

The Husaberg FE 650 E isn’t for everyone. It demands mechanical sympathy, rewards skilled riders, and punishes complacency. But for those willing to embrace its quirks, it’s a masterpiece of analog-era engineering. Today, it stands as a testament to a time when “big bore” meant something—a time when horsepower wasn’t just a number, but a feeling.

Whether you’re restoring one or upgrading your current ride, MOTOPARTS.store has the parts to keep your FE 650 E alive and kicking. Because legends deserve nothing less.
