Husqvarna FX 350 [2020-2022]: A Refined Enduro Weapon for the Discerning Rider

Introduction

The Husqvarna FX 350, produced between 2020 and 2022, represents a pinnacle of European enduro engineering. Designed to blur the line between a lightweight trail bike and a competitive race machine, this generation of the FX 350 has cemented its reputation as a versatile off-road companion. With its roots deeply embedded in Husqvarna’s motocross heritage, this bike isn’t just about raw power—it’s about precision, agility, and the kind of refinement that makes technical trails feel like a playground. After spending a day wrestling this machine through rocky ascents, forest singletracks, and open fire roads, it’s clear why this model remains a favorite among serious riders.

Engine Performance: A Carbureted Contradiction?

At the heart of the FX 350 lies a 349.7cc single-cylinder four-stroke engine, producing 58 HP (42.3 kW). While some might raise an eyebrow at the carbureted fuel system in an era dominated by fuel injection, Husqvarna’s choice here is deliberate. The Keihin carburetor delivers crisp throttle response, particularly in the mid-range, and simplifies tuning for riders who frequent extreme altitudes or modify their setups. That said, the lack of fuel injection does require occasional jetting adjustments for optimal performance in varying climates.

The engine’s character is surprisingly tractable for a high-strung enduro machine. The 11.1:1 compression ratio and polished camshafts with DLC-coated finger followers ensure smooth power delivery, reducing arm fatigue during long technical sections. The hydraulic clutch (Brembo in 2021-2022 models, Magura in 2020) offers buttery modulation, which is a godsend when navigating slippery roots or tight switchbacks.

Two engine maps and traction control—rare in this segment—allow riders to tailor power delivery. Map 1 softens the hit for slippery conditions, while Map 2 unleashes the full 58 HP for open terrain. Launch control, another unexpected feature, provides flawless starts on steep inclines.

Chassis and Handling: Precision Meets Durability

The FX 350’s chromoly steel frame strikes a balance between rigidity and flex, offering feedback without the harshness of aluminum. Paired with WP XACT suspension (48 mm forks up front and a linkage-equipped monoshock), the bike floats over obstacles that would unsettle lesser machines. With 310 mm (12.2 inches) of front travel and 300 mm (11.8 inches) at the rear, it’s equally at home blitzing through whoops or picking lines in rock gardens.

The 1482 mm (58.3-inch) wheelbase and 26.1° rake (26.5° in the 2020 model) lend sharp turn-in accuracy. At 100.5 kg (221.6 lbs), the FX 350 feels almost telepathic when flicking between trees or correcting mid-corner. Standing at 950 mm (37.4 inches), the seat height is tall but manageable for riders above 175 cm (5’9”), though shorter pilots might struggle at slow speeds.

Brembo brakes—twin-piston upfront and single-piston at the rear—deliver superb stopping power with minimal lever effort. The 220 mm (8.7-inch) rotors resist fade even during prolonged downhill abuse.

Electronics and Ergonomics: Modern Touches in a Rugged Package

The FX 350’s minimalist cockpit features a sleek handlebar clamp and intuitive switchgear. The Li-Ion battery (2.0 Ah in 2021-2022 models) shaves weight, aiding the bike’s nimble feel. Electric start is standard, a welcome convenience after stalling on a hillside.

Rider triangle is aggressive but comfortable. The footpegs are positioned for easy weight shifts, and the narrow midsection allows for effortless knee grip. Vibrations are minimal thanks to carefully engineered engine mounts.

Competition: How Does It Stack Up?

The FX 350’s closest rivals include:

1. KTM 350 EXC-F: Sharing much of its DNA with the Husqvarna, the KTM trades the FX’s refined suspension for a slightly stiffer setup. The EXC-F’s fuel-injected engine has a broader powerband, but the Husky’s carburetor offers easier field repairs.
2. Beta 350 RR: Lighter at 106 kg (233.7 lbs), the Beta excels in tight woods but lacks the Husqvarna’s electronic aids. Its air-cooled engine overheats more readily in slow terrain.
3. Yamaha WR250F: More affordable but down on power (45 HP), the WR250F suits beginners but feels outgunned in fast desert races.

The FX 350’s blend of race-ready specs and trail-friendly tuning makes it a standout for advanced riders prioritizing versatility.

Maintenance: Keeping Your FX 350 in Peak Condition

1. Air Filter Care: Frequent off-road use demands weekly filter checks. Consider a twin-air foam filter (available at MOTOPARTS.store) for improved airflow and durability.
2. Oil Changes: The 1.1-liter oil capacity requires changes every 15 hours. Use full-synthetic 10W-50 to protect the DLC-coated components.
3. Suspension Servicing: WP XACT forks benefit from biannual seal replacements. Upgrade to SKF seals for extended lifespan.
4. Chain Maintenance: The 5/8 x 1/4´ chain needs regular lubrication. A DID ERT3 chain from our store reduces stretch and sprocket wear.
5. Brake Upgrades: Swap pads to sintered variants for aggressive riding. MOTOPARTS.store stocks Brembo-compatible options.
