The pinnacle of Husqvarna supermoto competition, the FS 450 uses advanced engineering techniques to not only draw 63 hp from the 450cc motor, but also position the engine closer to the centre of gravity to vastly improve handling and manoeuvrability. The addition of launch control means perfect acceleration off the line, while class-leading ergonomics and traction control keep the rider in full control.
The SOHC cylinder head is incredibly compact and lightweight using a short profile with the camshaft located as close to the center of gravity as possible, significantly improving handling and agility. The lightweight valves are actuated via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.
A lightweight 5-speed gearbox produced by PANKL Racing Systems ensures the highest level of durability and reliability. The gear lever also features a unique design that prevents dirt build-up and keeps the lever tip in its original position, even in the toughest conditions, while an advanced gear sensor selects the ideal engine map for each gear.
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.
The FS 450 features a unique composite subframe showcasing 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. Through the use of computational dynamics, specific rigidity was engineered into the light and robust subframe, delivering outstanding handling and rider comfort.
The crankshaft is specifically positioned to harness the rotating mass in the ideal centre of gravity resulting in a lightweight and agile handling feel. As such, the inertia produced by the crankshaft is carefully calculated to deliver optimal traction and rideability from the powerful 450cc plant. A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 100 hours.
CNC MACHINED TRIPLE CLAMPS
The 16mm offset CNC-machined triple clamp works in harmony with the front forks, offering superior handling and stability. Furthermore, the triple clamps have been meticulously designed to evenly distribute the clamping force on the fork leg, maximizing contact area for optimal sensitivity and minimal friction and offering superior handling and stability. A 4-way handlebar adjustment is standard and allows for customisable ergonomics.
BREMBO HYDRAULIC CLUTCH
The reliable, high quality, Brembo 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 hot or cold conditions, as well as over time.
ANTI HOPPING CLUTCH
The SUTER anti hopping clutch prevents rear wheel instability and hopping when braking hard into the apex of a turn, for maximum control and perfect supermoto-style drifting.
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.
WP XACT SUSPENSION
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 the 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. The air pump needed to adjust the fork's air pressure is provided as standard. The 22mm diameter front axle provides advanced front end feedback under heavy braking into a corner. Additionally, the 28mm fork base offset offers advanced turning capability and agility for the optimal steering behaviour. Together with the fully adjustable WP XACT rear shock, Husqvarna offers superior suspension performance, feeling and comfort.
Exceptional stopping power is guaranteed by Brembo brakes, featuring a 4-piston radially mounted monoblock caliper in combination with a 310 mm disc at the front. A single piston caliper and a 220mm disc are fitted to the rear. The perfectly placed controls allow for optimal feel and balance under extreme conditions.
WHEELS AND TYRES
Black 16.5"/17" Alpina spoked wheels on the front and rear respectively, are lightweight and strong. They are complemented by Bridgestone 125/80 R420 and 165/65 R420 slick tyres for maximum grip, traction and agility.
Designed for easy, one-finger operation, the map switch is standard on the FS 450. 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 FS 450 features a 44mm Keihin throttle body. 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.
ELECTRIC START AND LI-ION BATTERY
Along with the benefit of an easy electric starting system, a lightweight Li-Ion 2.0 Ah battery is fitted to the FS 450. The Li-Ion battery weighs approx. 1 kg less than a conventional lead battery meaning the convenience of electric starting is delivered while keeping overall weight to a minimum.
