Features and Benefits
The SOHC engine is the
perfect example of the advanced engineering techniques used by
Husqvarna motorcycles offering a peak power of 63 hp at an
overall weight of just 61.3 pounds. Mass-centralization is key
in the engine design, enabling chassis engineers to position the
engine closer to the center of gravity for optimal handling and
The inertia produced by the
crankshaft is carefully calculated to deliver optimal traction
and ride-ability from the powerful 450 cc plant. The crankshaft
is specifically positioned to harness the rotating mass in the
ideal center of gravity resulting in a lightweight and agile
handling feel. A plain big end bearing comprising of two
force-fitted bearing shells ensure maximum reliability and
durability, guaranteeing long service intervals of 100 hours.
The crankcases are designed to
house the shaft arrangements and internals of the engine in the
position that offers the best possible centre of gravity.
Additionally, the position of the clutch shaft keeps the clutch
above the oil level resulting in decreased friction and
|Integrated Cooling System
The radiators are expertly
crafted by WP Performance Systems using high strength aluminum.
CFD (computational fluid dynamics) is utilized to channel air
through the radiators more efficiently and provide optimal
cooling in all conditions. The cooling system is integrated into
the frame increasing heat dissipation by channeling coolant
through the frame while eliminating the need for additional
hoses. Additionally, the radiator protectors do not only protect
against flying debris but also act as a brace divert any energy
from an impact around the radiator and into the frame.
|Chromoly Steel Frame
laser-cut and robot-welded frame expertly crafted by WP
Performance Systems is specifically designed with calculated
parameters of longitudinal and torsional flex. Aluminum engine
mountings benefit suspension functionality and feeling while
retaining a light, compact and strong package. The frame is
finished off with a premium white powder coating and standard
frame protectors guaranteeing supreme protection and durability.
|Composite Carbon Fiber Subframe
The composite subframe
is a design unique to Husqvarna showcasing pioneering
technologies and innovation. This 3 piece component is made up
of 30 % carbon fiber making it remarkably light (1.4 kg) and
also particularly strong. Specific care is taken to create a
certain rigidity for optimal handling and rider ergonomics.
|Magura Hydraulic Clutch
The reliable, high
quality, German-made 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.
|Magura Braking System
New for MY18 is a Magura
front and rear braking system. The system features a similar
layout to the previous design with improved sensitivity for a
more modulated feel while still retaining the highest level of
performance. 260mm disc front and 220mm rear.
|WP AER 48
The 48 mm split air fork features
an insulated air spring and pressurized oil chamber for
progressive and consistent damping. The component is lightweight
and easily adjustable via a single air pressure valve for
pre-load (on the left leg) as well as easy access clickers
adjusting damping with 30 clicks (on the right leg).
Additionally, the air pump needed to adjust air pressure in the
fork will be provided as standard.
|WP Rear Shock
The WP DCC rear shock is designed
to provide advanced damping characteristics while conforming to
a compact and lightweight design. With a pressure balance inside
the shock, damping is improved resulting in greater rider
comfort and handling while the outer contour of the reservoir
increases cooling. The component is also fully adjustable and
matched to a linkage system with a specific geometry to deliver
the best possible traction and progression with a rear wheel
travel of 300 mm.
|CNC Machined Triple Clamps
The 22 mm offset
black-anodized CNC machined triple clamps feature an integrated
rubber damping system that reduces vibration and increases rider
comfort. The triple clamps are expertly crafted using superior
techniques and materials to provide premium quality and
reliability. A 3-way handlebar adjustment is standard and allows
for customizable ergonomics.
Optimized for easy operation,
apart from changing between 2 different engine maps, the map
switch also activates launch control and traction control.
Traction control can be selected to an on or off position from
the switch and functions by analyzing throttle input from the
rider and the rate at which RPM increases in the engine. 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. This can be a distinct advantage in wet or
|44 mm Throttle Body
The FX 450 features
the same 44 mm Keihin throttle body found on the FC 450. The
injector is positioned to ensure the most efficient flow into
the combustion chamber while to ensure optimal throttle response
the throttle cable is mounted directly without a throttle
linkage providing more immediate throttle response and feeling.
The Keihin EMS is specifically
designed to be smaller, lighter and faster at processing data.
It integrates launch control for perfect starts, selectable
engine maps via the switch on the handlebar as well as traction
control. Combined with the new gear sensor, power delivery is
tailored for each gear.
Launch control is easily engaged
from the handlebar map switch. This function limits the amount
of power to the rear wheel, improving traction and preventing
loss of control under hard acceleration at the start line.
|Electric Starter Along
with the benefit of easy starting the electric starting system
is combined with a compact Li-Ion battery which is 2.2 pounds
lighter than a conventional battery. The wiring harness has been
purposefully designed so that the rear subframe can be removed
without having to remove any wiring.
