FC 350

  • Choose Colour
With the agility of a 250 and a 450-rivalling power-to-weight ratio, the FC 350 strikes a competitive balance between power and handling. This appeals to both professional and amateur riders alike, making for a more user-friendly riding experience in all conditions. It is this versatility, paired with intelligent traction and launch control, which makes the FC 350 one of the most multitalented motocrossers on the market.

For 2022 we upgraded the hydraulic clutch to an all new high-performance Brembo system for perfect modulation at all times. On top, striking new dark blue and white graphics stylishly adorn the Swedish inspired design.

01. Performance

Performance

Engine

Weighing in at only 27.2 kg and churning out a maximum power output of 58 hp, the motor in the FC 350 is designed with performance as a priority. It is also one of the lightest engines in its class.

Cylinder head

The FC 350 features an advanced DOHC cylinder head layout meticulously engineered to deliver every fraction of performance. The internals feature polished camshafts and DLC coated finger followers, resulting in minimal friction and unsurpassed overall performance, allowing the engine to rev freely to 13,400 rpm.

Cylinder & piston

An 88 mm bore and 57.5 mm stroke cylinder features a compression ratio of 14.2:1 and a large diameter yet lightweight forged bridged-box-type piston. As a result, the low oscillating mass delivers exceptional power, high revs and a very wide power band.

Crankshaft

At the centre of the high-output, high-revving FC 350 engine is a crankshaft featuring a plain big end bearing rotating on two force-fitted bearing shells, ensuring maximum reliability and durability, guaranteeing long service intervals of 100 hours.

INTERCHANGABLE AIRBOX COVER

Designed with precisely positioned inlet ducts aimed at reducing drag and air flow deformation, the airbox ensures unrestricted airflow with maximum filter protection. The TWIN AIR filter is easily accessed without tools, by simply removing the left side panel for easy maintenance. Offering further performance customisation, the FC 350 is delivered with an additional airbox cover that can be changed without the use of any tools for a sharper throttle response according to rider preference or track conditions.

02. Control

Control

Functional bodywork

Clean, Swedish-inspired design and ergonomics are tailored to deliver exceptional comfort and control, enabling riders to perform at the highest level for extended periods of time. Adapted after countless hours of testing, the contact points are specifically positioned to allow seamless movement around the motorcycle.

Frame

Engineered with carefully calculated parameters of longitudinal and torsional flex, the frame features improved rider feedback, energy absorption and straight-line stability. The frame is finished off in a premium blue powder coating and standard frame protectors guaranteeing superior protection and durability.

Carbon fibre subframe

Carbon fibre is renowned for its light weight and high strength. For those reasons, the Husqvarna MX range features a unique composite subframe made from 30% carbon fibre. Specific rigidity is engineered into the subframe to deliver optimal handling and rider ergonomics.

Swingarm

The swingarm is manufactured from a single piece of aluminium using a gravity die-cast production process. This gives the swingarm exceptional strength while keeping the weight to a minimum. Chain adjustment markings are also visible from above to make for simpler adjustment.

Technology

Map switch

Designed for easy, one-finger operation, the map switch is standard on the FC 350. This allows riders to easily select between 2 engine maps, activate the launch control or toggle the traction control feature.

Engine management system

The KEIHIN EMS is designed to be small, lightweight and fast at processing data. It integrates launch control for perfect starts, selectable engine maps via the switch on the handlebar as well as traction control.

44 mm throttle body

The FC 350 features a 44 mm KEIHIN throttle body ensuring the most efficient fuel flow into the combustion chamber while maintaining optimal throttle response.

Electric start and Li-Ion battery

As with all 4-strokes in the Husqvarna motocross range, the FC 350 starts with the ease of pressing a button thanks to electric start. A lightweight Li-Ion 2.0 Ah battery is fitted, giving the convenience of electric starting while keeping overall weight to a minimum.

Components

Cooling system

Made using high-strength aluminium, the cooling system on the FC 350 features computational fluid dynamics to channel air through the radiators more efficiently. The cooling system is also integrated into the frame allowing improved cooling by channelling coolant through the frame while eliminating the need for additional hoses.

Tool-less airbox design

Easy access to the TWIN AIR filter is possible without tools, for quicker cleaning and easier maintenance. Precision inlet ducts maximise airflow and offer increased levels of filter protection.

Self-cleaning footpegs

The FC 350 frame features an innovative, self-cleaning footpeg mount that helps prevent mud build-up, springing back to the original position for sure footing at all times.

Hydraulic clutch

The new, high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation and perfect modulation in every condition. Meaning that play is constantly compensated so that the pressure point, and function of the clutch remain identical in cold or hot conditions as well as over time. Countless hours of race focused testing have proven the high-quality, Italian-made Brembo hydraulic systems exceptional reliability.
