2021 Husqvarna FC 350

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.

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 FIBER 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.

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.

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.
