Husqvarna FC 350 [2014-2015]: A Motocross Weapon That Stands the Test of Time

Introduction

The Husqvarna FC 350 from the 2014-2015 model years remains a fascinating study in motocross engineering – a machine that straddles the line between agility and aggression with remarkable poise. Designed for riders who crave the torque of a 450cc machine but prefer the flickable nature of a 250cc, this 350cc Austrian-built thumper carved its own niche in the motocross world. Two years after its debut, it still feels like a well-kept secret among riders who value precision over brute force. Let’s dissect why this bike continues to turn heads on tracks and trails.

Engine Performance: The Sweet Spot of Power Delivery

At the heart of the FC 350 lies a 349.7cc liquid-cooled single-cylinder engine – a masterpiece of balance. The 88mm bore and 57.5mm stroke (3.46 x 2.26 inches) create an oversquare design that rewards riders with a broad powerband. With 45 horsepower (32.8 kW) pushing just 106.4 kg (234.6 lbs), the power-to-weight ratio of 0.423 HP/kg feels like having a cheetah on a leash – controlled fury waiting to be unleashed.

The fuel injection system deserves special praise. Unlike carbureted rivals of its era, the FC 350 delivers crisp throttle response across all RPM ranges. The 5-speed gearbox is a curious choice (most MX bikes stick to 4 speeds), but it works in the 350's favor. Third gear becomes the "do-it-all" ratio for technical sections, while fifth lets you stretch its legs on fast straights without screaming at redline.

Riding impressions? The engine pulls cleanly from low revs, avoiding the sudden hit of 450cc monsters. Mid-range is where it truly shines – a surge of torque that rockets you out of corners without requiring frantic clutch work. Top-end power tapers off gently, making it more forgiving for intermediate riders while still satisfying experts.

Chassis and Handling: Precision Meets WP Wizardry

The chrome-molybdenum steel frame strikes an ideal balance between stiffness and flex. Paired with the WP Suspension 4CS (Four Chamber System) forks (48mm upper tube diameter) and WP Monoshock rear, the FC 350 dances through obstacles with Euro-bred finesse.

Key numbers tell part of the story: - Front wheel travel: 300mm (11.8") - Rear wheel travel: 317mm (12.5") - Rake angle: 26.5° - Wheelbase: 1482mm (58.3")

But the real magic happens on the track. The 970mm (38.2") seat height positions riders in an aggressive attack stance, while the 345mm (13.6") ground clearance laughs at deep ruts. The front end sticks to berms like Velcro, and the bike changes direction with minimal input – a flick of the hips is all it takes.

Brembo’s hydraulic clutch and single 260mm discs (front/rear) provide stoic braking performance. The 520 chain drives power efficiently to the 140/90-18 rear tire, hooking up predictably even on hardpack.

Ergonomics: Built for War, Designed for Comfort

Husqvarna nailed the rider triangle here. Narrow bodywork lets you grip the bike with your knees effortlessly, while the flat seat-to-peg relationship (400mm peg-to-seat distance) suits both seated cruising and aggressive standing attacks. The handlebar bend feels neutral – not too low for cornering, not too high for jumps. After a 30-minute moto, you’ll appreciate how the weight distribution (59% front/41% rear) minimizes arm pump.

Competition: How the FC 350 Stacks Up

In the 350cc class, the Husqvarna faced stiff competition:

1. KTM 350 SX-F (2014): The FC 350's orange cousin shared its engine architecture but differed in mapping. The KTM felt more aggressive high-RPM, while the Husky prioritized mid-range grunt. Suspension tuning also varied – WP’s 4CS forks on the Husky vs. KTM’s conventional OC forks.

2. Yamaha YZ250F (2015): The blue bomber’s 250cc engine required more clutch work but revved freely. Yamaha’s KYB suspension felt plusher on small bumps, but the Husky’s WP setup handled big hits better.

3. Honda CRF250R (2014): Honda’s legendary cornering ability met its match in the FC 350’s chassis. While the CRF felt lighter at low speeds, the Husky’s torque advantage was undeniable out of corners.

4. Kawasaki KX250F (2015): The green machine’s Showa suspension competed well, but its engine lacked the Husky’s broad power spread.

Where the FC 350 excelled was versatility. It bridged the gap between 250cc agility and 450cc power, making it ideal for riders transitioning between classes or those wanting a less exhausting ride.

Maintenance: Keeping Your Swedish Stallion Healthy

As MOTOPARTS.store journalists, we’ve seen these bikes age gracefully – with proper care. Here’s your survival guide:

1. Oil Changes Are Sacred
   The dual Eaton oil pumps (lubrication and scavenge) demand clean blood. Change oil every 10 engine hours using 10W-50 synthetic. Don’t forget the stainless steel oil filter – ours (part #HUSKY-OIL350) fits perfectly.

2. Air Filter Rituals
   That 90/90-21 front tire kicks up serious dirt. Clean the air filter after every ride. Our TwinAir filter kit (#HUSKY-AIR350) includes reusable skins and sealing grease.

3. Suspension Service
   WP’s 4CS forks perform best with fresh 5W oil. Rebuild every 50 hours. Check linkage bearings annually – our All Balls kit (#HUSKY-LINK350) prevents costly swingarm seizures.

4. Brake Fluid Flush
   Brembo components love DOT 4/5.1 fluid. Replace annually or when lever feel degrades. Try our Braking Brand rotors (#HUSKY-BRAKE350) for enhanced bite.

5. Cooling System Checks
   The 1.3L radiator capacity needs protection. Use ethylene glycol-based coolant and inspect hoses for micro-cracks. Our silicone hose kit (#HUSKY-COOL350) adds durability.

6. Chain & Sprocket Love
   The 520 chain lasts longer with proper tension (55-60mm free play). Replace sprockets as a set – we recommend Supersprox combos (#HUSKY-SPRO350) for longevity.
