FX 350

01. Performance

Engine

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

Cylinder head

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

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. As a result of extensive testing, the slim contact points make shifting between riding positions easier and allow the rider to flow with movement. The flat seat profile, together with the seat cover texture, deliver superior comfort and control in all conditions.

FRAME

The chromium molybdenum steel frame is expertly crafted using laser-cut, robot-welded, hydro-formed tubes, ensuring the highest level of precision and quality. The specifically crafted geometry utilises advanced longitudinal and torsional flex characteristics, for unparalleled rider feedback, energy absorption and exceptional straight-line stability. The frame is finished off in a premium blue powder coating with standard frame protectors for superior protection and durability.

COMPOSITE CARBON FIBRE SUBFRAME

The carbon composite subframe is unique to Husqvarna Motorcycles and showcases advanced production technology and innovation. Using 70% polyamide and 30% carbon fibre, the 2-piece subframe has a total weight of just over 1 kg. With the help of computational dynamics, specific rigidity was engineered into the light and robust subframe, delivering outstanding handling and rider comfort.

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.

WP XACT FRONT FORK

The 48 mm split air fork features a capsulated air spring and pressurized oil chamber for progressive and consistent damping. Pressure peaks were reduced through extended oil and air bypasses. In combination with a new midvalve damping system, the fork provides exceptional feedback and rider comfort. The setting is easily adjusted via the single air pressure pre-load valve, as well as through easy access click adjusters for compression and rebound. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard.

WP XACT REAR SHOCK

The WP XACT rear shock provides advanced damping characteristics for unsurpassed traction and energy absorption. A pressure balance inside the shock ensures consistent damping, resulting in superior rider comfort and feeling. The fully adjustable component delivers 300 mm rear wheel travel, as well as unrivalled traction, feeling and energy absorption.

03. Components

COOLING SYSTEM

Made using high-strength aluminium, the cooling system on the FX 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 FX 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.

04. Technology

MAP SWITCH

Designed for easy, one-finger operation, the map switch is standard on the FX 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 FX 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 range, the FX 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.
