Husqvarna FE 501 [2014 - 2016]: A Legacy of Enduro Dominance

Introduction

The Husqvarna FE 501 isn’t just a motorcycle—it’s a statement. Built for riders who demand uncompromising performance in the most unforgiving terrain, this generation (2014–2016) redefined what a modern enduro machine could achieve. Whether you’re carving through rocky trails, charging up steep inclines, or navigating technical singletrack, the FE 501 balances raw power with precision engineering. Having spent time aboard this Swedish beast, it’s clear why it remains a benchmark in the dual-sport and hardcore enduro segments.

The Husqvarna FE 501’s aggressive stance and minimalist design hint at its off-road prowess.

Engine Performance: Torque Meets Refinement

At the heart of the FE 501 lies a 510.4cc SOHC single-cylinder engine, a masterpiece of enduro-specific engineering. With a bore and stroke of 95mm x 72mm, this powerplant delivers a visceral yet controlled punch. The 12.8:1 compression ratio and Keihin fuel injection ensure crisp throttle response, whether you’re lugging through mud or revving out on open fire roads.

Key Highlights:
- 45 HP (32.8 kW): While peak power sits at 45 hp, it’s the broad torque curve that impresses. The engine pulls strongly from as low as 2,000 rpm, making it forgiving in technical sections.
- Vibration Damping: A multifunctional counterbalance shaft cancels out vibrations, allowing riders to push for hours without fatigue.
- Electric Start: Reliable electric starting (with a retrofittable kickstarter) eliminates the stress of stall recoveries in tricky spots.

The König bridge-box piston and titanium intake valves reduce reciprocating mass, contributing to the engine’s free-revving character. On the trail, the FE 501 feels eager but never unruly—a testament to Husqvarna’s focus on rideability over brute force.

Chassis and Suspension: Precision in Motion

The FE 501’s chrome-molybdenum frame strikes a balance between flex and rigidity.

The FE 501’s chassis is a study in controlled flex. The chromium molybdenum steel frame features longitudinal give to absorb rear-wheel impacts, while torsional rigidity ensures razor-sharp handling. Paired with a polyamide subframe (30% lighter than aluminum), the bike communicates terrain feedback without punishing the rider.

WP 4CS Forks:
- 300mm Travel (11.8 in): The 48mm inverted forks use a 4-chamber system for consistent damping. Adjusting compression and rebound is intuitive, with clickers accessible mid-ride.
- Triple Clamp Updates (2015): Revised clamps improved front fender stability and fork leg alignment, enhancing steering precision.

Rear Suspension:
- WP DCC Shock with Linkage: Offering 330mm (13 in) of travel, the shock excels in both high-speed chatter and deep hits. The linkage system allows progressive tuning—stiffen it for motocross-style jumps or soften for enduro roots.

Handling and Ergonomics: Built for Attack

Standing at 970mm (38.2 in), the seat height is tall but manageable for riders over 5’10”. The narrow midsection lets you grip the bike with your knees, while the updated MY15 seat cover provides just enough grip without chafing.

Agility Notes:
- Steering Geometry: A 63.5° head angle and 107mm (4.2 in) trail strike a balance between stability and quick turn-in.
- Swingarm Design: The one-piece aluminum swingarm optimizes traction, flexing subtly to maintain contact on loose surfaces.

Brembo brakes—260mm front/220mm rear—deliver stoppie-ready power with sublime modulation. Michelin Enduro Competition tires (21” front, 18” rear) bite into everything from loam to granite.

Brembo’s 4-piston caliper and wave rotor offer relentless stopping power.

Competition: How the FE 501 Stacks Up

The FE 501’s rivals in the 500cc enduro segment are fierce, but it holds its ground with unique advantages:

1. KTM 500 EXC-F

• Similar DNA (shared parentage under Pierer Mobility Group), but the FE 501’s WP 4CS forks edge out KTM’s OC forks in mid-stroke support.
• Husqvarna’s subframe and airbox design offer better debris protection during muddy rides.

2. Beta 500 RR-S

• Beta’s smoother power delivery suits beginners, but the FE 501’s aggressive torque and lighter chassis (113.5 kg vs. Beta’s 118 kg) favor technical experts.

3. Yamaha WR450F

• Yamaha’s 5-speed gearbox can’t match the Husqvarna’s 6-speed versatility. The WR450F also feels bulkier at slower speeds.

Verdict: The FE 501 shines for riders prioritizing premium components (Brembo, WP) and a race-ready chassis straight from the showroom.

Maintenance: Keeping the Beast Alive

The FE 501’s service-friendly layout simplifies routine upkeep.

Critical Service Intervals:

• Oil Changes: Every 15 hours (1.2L of SAE 10W-50). Use a high-quality filter (MOTOPARTS.store part #MP-HUSQ-OILFILTER).
• Air Filter: Clean every ride in dusty conditions. Upgrade to a Twin Air dual-stage filter (#MP-TWIN-AIR-HUSQ) for better particle trapping.
• Valve Checks: Every 30 hours. Intake: 0.10–0.15mm (0.004–0.006 in), Exhaust: 0.12–0.17mm (0.005–0.007 in).
• Chain Adjustment: The 520 X-ring chain lasts longer with regular lubrication. Replace with a DID ERV3 chain (#MP-DID-ERV3) when stretched.

Common Upgrades:

• Radiator Guards: The stock cooling system (1.2L capacity) is robust, but add bulletproof guards (#MP-HUSQ-RADGUARD) for rock strikes.
• Sprocket Kits: Swap to a 13-tooth front sprocket (#MP-JT-SPROCKET13) for tighter trails.
• Brake Pads: Swap stock pads for sintered metal (#MP-BREMBO-SINTERED) in wet conditions.
