Husaberg FE 501 [2013-2014]: A Swedish Weapon for the Dirt

Introduction

The Husaberg FE 501 (2013-2014) is a machine that demands respect. Born from Sweden’s obsession with precision and Austria’s engineering prowess (thanks to its KTM lineage), this enduro bike straddles the line between raw power and finesse. Designed for riders who treat mountain trails as their playground, the FE 501 isn’t just a dirt bike—it’s a statement. With its signature blue-and-yellow livery and minimalist Swedish design ethos, this generation of FE 501 remains a cult favorite among hardcore offroad enthusiasts.

The 2013-2014 models represent the end of an era for Husaberg, as the brand would later merge fully into Husqvarna. But these final iterations are anything but forgettable. Updates like the electric-start-only system for 2014 (the 2013 model retains a backup kickstarter) and refined WP suspension make these bikes a compelling choice even today. Let’s dissect what makes this machine tick—and why it still turns heads on trails worldwide.

Engine Performance: Controlled Fury

At the heart of the FE 501 lies a 510.4cc (31.14 cubic inches) liquid-cooled single-cylinder engine—a beast that’s as tractable as it is explosive. The 95mm x 72mm bore and stroke ratio prioritizes torque over screaming revs, delivering a punchy low-end that’s perfect for lofting the front wheel over logs or clawing up rocky inclines.

Key Highlights:
- Fuel Injection: The Keihin EFI system (introduced in 2013) eliminates carburetor fuss, providing crisp throttle response even at altitude.
- 12.2:1 Compression: Requires premium fuel but rewards with explosive power when you crack the throttle.
- 6-Speed Gearbox: A versatile spread of ratios, with 1st gear for technical crawls and 6th capable of 140 km/h (87 mph) bursts on fire roads.

Riding the FE 501 feels like taming a wildfire. The engine’s character is unmistakably aggressive, yet it’s manageable thanks to a linear power curve. On tight singletrack, the bike chugs along smoothly at low RPMs, but twist the throttle, and it transforms into a snarling animal. The Brembo hydraulic clutch ensures smooth modulation, critical when navigating slippery roots or loose gravel.

The switch to electric-only starting for 2014 polarizes purists, but the reliability of the 12V 7Ah battery and the convenience of a button-start in muddy conditions can’t be overstated. For 2013 riders, the kickstarter is a reassuring backup.

Chassis and Handling: Precision in the Rough

Husaberg’s signature chrome-molybdenum steel frame is a work of art. The central tube design keeps weight centralized, contributing to a claimed dry weight of 111-112 kg (244-247 lbs)—remarkably light for a 500cc+ enduro bike. Paired with WP suspension, the FE 501 feels like an extension of your body when the terrain turns chaotic.

Suspension Setup:
- Front: WP 48mm 4CS forks (2014) / WP USD 48mm Closed Cartridge (2013) with 292-300mm (11.5-11.8 in) of travel.
- Rear: WP PDS (Progressive Damping System) shock with 335mm (13.2 in) of travel.

The PDS rear suspension eliminates linkage, reducing weight and complexity. While some riders miss the adjustability of linkage systems, the PDS shines in brutal, high-speed chop, staying composed where others wallow. The front forks absorb small bumps with plushness but firm up predictably during hard braking or big hits.

Brakes: Brembo’s single 210mm discs (front/rear) offer ample stopping power. The front brake lacks the initial bite of a dual-disc setup but rewards with progressive feel—ideal for slippery descents.

Tires: The 90/90-21 front and 140/80-18 rear tire combo strikes a balance between agility and traction. Swap the stock tires for gummier rubber if you’re tackling snotty mud or rock gardens.

Ergonomics: Tall, Slim, and Ready to Dominate

At 970mm (38.2 in), the seat height is intimidating for shorter riders but perfect for standing attacks on technical terrain. The narrow frame lets you grip the bike with your knees effortlessly, while the handlebar positioning encourages an aggressive, forward-leaning stance.

The 9.5L (2.51-gallon) fuel tank is small but adequate for 80-100 km (50-60 mi) of hard riding. For enduro races or long adventures, aftermarket tanks are a wise investment—something MOTOPARTS.store stocks extensively.

Competition: How the FE 501 Stacks Up

KTM 500 EXC

KTM’s 500 EXC is the FE 501’s closest relative—literally, given their shared DNA. The KTM edges ahead with slightly sharper throttle response and a broader dealer network. However, the Husaberg’s PDS rear suspension feels more planted in whoops, and its steel frame absorbs vibration better on long rides.

Beta 520 RR

Beta’s 520 RR is a trials-inspired alternative, with a softer power delivery that favors technical terrain. The FE 501 counters with superior high-speed stability and a more robust aftermarket parts ecosystem.

Yamaha WR450F

Yamaha’s WR450F is tamer and more beginner-friendly, but its 450cc engine lacks the FE 501’s arm-stretching torque. The Yamaha’s suspension also feels undersprung for aggressive riders compared to WP’s premium setup.

Verdict: The FE 501 isn’t the newest or most refined bike in its class, but its raw character and niche appeal make it a favorite for riders who value individuality.

Maintenance: Keeping the Beast Alive

The FE 501 is a high-performance machine that demands meticulous care. Here’s what you need to know:

• Oil Changes: Use SAE 10W-50 synthetic oil every 15-20 hours. The 1.2L (1.27-quart) capacity is small, so frequent changes are critical.
• Chain Maintenance: The 520 chain with 120 links requires regular cleaning and tension checks. Upgrade to a premium O-ring chain for longevity.
• Cooling System: The 1L (0.26-gallon) coolant capacity is sufficient, but monitor levels closely in extreme heat.
• Valve Checks: Every 30 hours. The SOHC design simplifies adjustments compared to DOHC rivals.
• Battery Care: The 12V 7Ah battery is reliable, but keep it on a tender during offseason storage.

Pro Tip: The FE 501’s Brembo clutch components are durable, but MOTOPARTS.store offers upgraded lever kits for improved ergonomics during long rides.
