Husqvarna FE 350 (2017-2018): The Sweet Spot Between Agility and Power

Introduction

The Husqvarna FE 350 sits in a Goldilocks zone of enduro motorcycles. Designed for riders who crave the nimble handling of a 250cc machine but refuse to compromise on torque and mid-range punch, this 349.7cc Austrian-engineered beast redefines versatility in off-road riding. Having spent a day thrashing a well-maintained 2018 model through rocky trails, muddy ruts, and open fire roads, it’s clear why this generation remains a benchmark for balanced performance. Let’s dissect what makes this bike a standout in the enduro world.

Engine Performance: Precision Meets Ferocity

At the heart of the FE 350 lies a liquid-cooled, single-cylinder DOHC engine that’s as sophisticated as it is relentless. With 45 hp (32.8 kW) on tap, this isn’t just a “tweener” bike—it’s a legitimate contender that shadows 450cc competitors in power-to-weight ratios. The magic comes from its 88 x 57.5 mm bore/stroke configuration, favoring high-revving agility while retaining enough grunt to tractor up technical climbs.

What struck me most was the Keihin EFI system’s responsiveness. Crack the throttle open, and the bike surges forward with a linear, almost electric delivery—no hiccups, no flat spots. The DLC-coated finger followers and titanium valves (36.3 mm intake / 29.1 mm exhaust) ensure minimal friction, letting the engine rev freely to its 12,000 RPM limit. Yet, it’s remarkably tractable at low RPMs, chugging through mud without stalling.

The 6-speed transmission is a revelation. Shifts are crisp, aided by the no-dirt gear lever that never clogged up, even after plowing through sludge. The Magura hydraulic clutch requires just a finger’s effort, making feathering effortless during tight switchbacks.

Key Highlights:
- Traction Control: Husqvarna’s system isn’t a gimmick. On loose gravel, it subtly modulates power to keep the rear wheel hooked up without neutering acceleration.
- Map Switch: Toggling between maps mid-ride transforms the bike. The aggressive setting turns it into a fire-breathing rally machine, while the mild mode tames it for slippery roots.

Chassis and Handling: A Dance Partner for the Dirt

Husqvarna’s 25CrMo4 steel frame is a masterpiece of flex engineering. At 109.2 kg (240.7 lbs) dry, the FE 350 flicks side-to-side like a trials bike but remains planted at speed. The WP Xplor 48mm forks (300mm travel) and WP Monoshock (330mm travel) deserve a standing ovation. Over jagged rocks, the front end glides without deflection, while the rear linkage soaks up square-edged hits like a sponge.

Steering is telepathic, thanks to the 63.5° head angle and 107mm trail. The bike carves into corners with the urgency of a motocrosser but stays stable at 90+ km/h (56 mph) on straights. The DID rims wrapped in Michelin Enduro Competition tires (90/90-21 front, 140/90-18 rear) provided tenacious grip, even on off-camber shale.

Standout Feature:
- Weight Distribution: The compact engine placement and polyamide subframe centralize mass. Hopping over logs or pivoting on the pegs felt instinctive—no wrestling with a top-heavy chassis.

Ergonomics: Built for War, Designed for Comfort

At 970mm (38.2"), the seat height is intimidating for shorter riders but perfect for stand-up riding. The narrow midsection lets you grip the bike with your knees effortlessly, while the Neken handlebar offers a natural, upright posture. Even after three hours of punishing trails, the firm seat and vibration-damped pegs left no numbness.

The Magura brakes (260mm front / 220mm rear) are faultless. The front two-piston caliper delivers progressive bite, avoiding the wooden feel of some competitors. On steep descents, modulation was precise—no lockups, even with gloves caked in mud.

Competition: How the FE 350 Stacks Up

1. KTM 350 EXC-F
The FE 350’s closest sibling shares its engine architecture but differs in suspension tuning. KTM’s WP Xplor setup is slightly stiffer, favoring faster riders, while Husqvarna’s softer valving caters to technical terrain. The FE also edges out in aesthetics with its signature white/blue livery.

2. Yamaha WR250F
Yamaha’s 250cc rival is lighter (106 kg / 233 lbs) but lacks the FE’s mid-range punch. The WR’s carbureted engine feels archaic compared to Husqvarna’s EFI. However, Yamaha’s reliability is legendary—something to consider for riders logging 200+ hours annually.

3. Beta 350 RR
Beta’s offering has a mellower powerband and plush suspension, ideal for beginners. But the FE 350 dominates in outright speed and features like traction control. Beta counters with a street-legal variant, which Husqvarna lacks.

Verdict: The FE 350 isn’t the cheapest nor the most docile, but it’s the most complete package for riders who demand race-ready performance with trail-friendly manners.

Maintenance: Keeping the Beast Alive

The FE 350 isn’t a “set it and forget it” machine, but its service intervals are reasonable for a high-strung enduro:
- Oil Changes: Every 15 hours using Motorex Cross Power 4T 10W-50. The dual oil filters are easily accessible.
- Air Filter: Clean every ride in dusty conditions. Upgrade to a Twin Air filter for better airflow.
- Valve Checks: Every 30 hours. Titanium valves hold clearance well, but shim adjustments are inevitable.
- Suspension: Rebuild WP forks every 80-100 hours. Consider MOTOPARTS.store’s SKF seal kit to reduce stiction.

Critical Tip: The DDS clutch is durable but intolerant of poor adjustment. Use Magura Blood mineral oil for consistent lever feel.
