2021 Husqvarna FC350 : BALANCED PERFORMANCE.

Introducing the 2021 Husqvarna FC350…

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.

Husqvarna Motorcycles North America, Inc. is pleased to announce the launch of the new MY21 motocross range, highlighting nine true-performance minibikes and full-sized motorcycles, in addition to three cross-country machines that all deliver superior riding experiences. Featuring the latest technological advancements, all machines ensure uncompromised power-to-weight, leading ergonomics and aesthetics.

For 2021 Husqvarna Motorcycles has focused on further improving suspension performance and handling by adding new hardware to the WP XACT forks with AER technology including a new mid-valve damping system for increased rider comfort on landings, as well as reducing pressure peaks for consistent damping performance. Additionally, new low-friction linkage seals offer refined suspension response on the WP XACT shock.

Delivering minimal weight, ease of handling and the highest levels of performance, Husqvarna Motorcycles’ TC and TXi lineup features the latest 2-stroke technology with class-leading power and unrivaled attention-to-detail. Advanced ergonomics and modern bodywork combine to ensure all TC and TXi machines offer superior on-track comfort and control in all riding conditions.

Engineered to keep ahead of the field, Husqvarna Motorcycles’ 4-stroke models feature compact and modern engines with internal shaft arrangements at the ideal center of gravity to notably benefit handling and maneuverability. At the top of the range, the powerful and smooth FC 450 engine has been enhanced with several new internal pieces as well as revised mapping to keep it running at the front of the pack. Modern electronics and launch control throughout the lineup ensure perfect acceleration. Accompanying the launch of the 2021 motocross range is the new Husqvarna Motorcycles app and Connectivity Unit, coming to the Technical Accessories lineup this summer. The app enables riders to adjust their FC’s engine mapping and gives recommendations for the optimum suspension setting. Additionally, it allows for precise customization and personalization, while improving overall rideability.

2021 Husqvarna FC350 Totalmotorcycle.com Features and Benefits

Performance
Engine

The 350 cc DOHC engine weighs in at only 60 pounds with a maximum power output that rivals 450 cc machines. The engine is specifically designed with performance, weight and mass centralisation as key areas. As a result, all shaft arrangements have been positioned to allow oscillating masses to occupy the ideal center of gravity while all parts are engineered to offer the best performance while adding the least possible weight.

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.

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

The use of carbon fiber strips away weight, improving weight distribution and bringing weight closer to the center of gravity for precise handling. The composition of the material is 30% carbon fiber and the overall 3-piece construction is remarkably light but also very strong for an overall weight of 3.1 pounds. Additionally, a specific rigidity has been calculated in the component for 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

Optimized for easy operation, the map switch selects between two engine maps, operates launch control and activates a traction control feature. Traction control works by analyzing throttle input from the rider and the rate at which the RPM increases. If the RPM increases too quickly, the EMS will register a loss of grip and reduce the amount of power to the rear wheel ensuring maximum traction.

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

Along with the benefit of easy starting, the standard electric starting system is combined with a new compact Li-Ion battery which is 2.2 pounds lighter than a conventional battery.

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.

Magura hydraulic clutch

Reliable, high quality and German-made, the MAGURA hydraulic clutch system is almost maintenance-free, and guarantees even wear and perfect feel in all riding conditions. This means that modulation and play on the lever are constantly compensated so that the pressure point and clutch function remain identical in cold or hot conditions.
