Weighing just 26.8 kilograms, its lightweight construction plays a pivotal role in improving overall agility and responsiveness. Positioned strategically to centralize mass, the engine enhances handling by promoting better balance and maneuverability, while also significantly boosting anti-squat behavior in the chassis.Furthermore, servicing the FS 450 engine is notably easier compared to previous models, thanks to integrated service markers on the engine cases. These markers streamline maintenance tasks by clearly indicating service points and intervals, ensuring smoother upkeep and prolonged optimal performance.
Cylinder head
The SOHC cylinder head is incredibly compact with the camshaft positioned as close to the centre of gravity as possible to aid handling and agility. A durable, fine-punched cam chain runs on low-friction chain guides for optimal efficiency and reliability with a single oil spray jet guaranteeing effective cooling. The lightweight valves are actuated via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.
Cylinder & piston
The lightweight aluminium cylinder is undoubtedly an engineering masterpiece and features a 95 mm bore with a 63.4 mm stroke. Inside, the CP bridged-box-type piston features anodised annular grooves, adding durability and longer service intervals at a weight of just 327 g. The compression ratio is 13.6:1 for incredible peak power, which ensures the FS 450 remains firmly at the front of the pack.
Crankshaft
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 450 cc engine. A plain big end bearing comprising two force-fitted bearing shells ensure maximum reliability and durability, for long service intervals of 90 hours.
Crankcases
Designed for optimised mass centralisation, the FS 450 crankcases arrange the shafts and engine internals in the perfect position to achieve the best possible handling. Manufactured using a high-pressure die-cast production process, the result is a thin, exceptionally strong wall thickness at the lowest possible weight.
Anti hopping clutch
The FS 450 features a Suter anti-hopping clutch to prevent rear wheel instability and hopping when braking hard into the apex of a turn for total control and perfect drifting. It reduces the physical efforts required by the rider and improves lap times.

Integrated into the shift drum, the Quickshifter sensor can be activated by pressing the QS marked button on the Map Select Switch to further aid seamless upshifting.
Lightweight frame
With an optimised distribution of material around the steering head and upper shock mount, the frame delivers confidence-inspiring handling and assured stability when entering corners. To complement the overall look of the machine, the chromium molybdenum chassis is finished with a premium, metallic blue powder coating. The finishing touches are the frame protectors, which not only protect the paintwork, but also provide riders with additional grip, even in the toughest conditions.
Polyamide-reinforced aluminium subframe
Made from 60% polyamide and 40% aluminium, the two-piece subframe ensures exceptional strength and durability at an overall weight of just 1.8 kg. The lower subframe spars and frame mounts are manufactured from cast aluminium for reliability while the upper section of the subframe is made from injection-molded polyamide. The materials used to construct the subframe are chosen as they enable specific flex characteristics at the lowest possible weight.
CNC machined triple clamps
Working in perfect unison with the frame design and suspension set-up, the CNC-machined triple clamps provide precisely calculated geometry for increased stability. Customised handlebar flex can be achieved by the handlebar clamp, which offers two mounting options – rubber-damped for less vibration, or fixed for enhanced front-end feedback. The upper triple clamp ensures a smooth fork action and plays a vital role in the alignment of the front wheel for superior handling.
WP XACT front suspension
The FS 450 is equipped with 48 mm WP XACT Closed Cartridge forks. These offer consistent damping thanks to an advanced design that includes a unique mid-valve piston concept to optimise oil flow and prevent foaming. Bottoming resistance is assured thanks to the hydrostop, which applies a progressive damping force in the last 68 mm of travel, to ensure no loss of forward momentum after heavy landings. Compression and rebound settings are easily adjustable by hand, with the pump used to adjust the air pressure in the forks, which are provided with each machine. The fork seals are made by industry leader SKF and offer exceptional protection against dirt intrusion for continued suspension performance.
WP XACT shock absorber
The WP XACT rear shock offers 266 mm of travel and features a Computational Fluid Dynamics (CFD) optimised main piston, ensuring superior initial comfort and predictable performance in all conditions. To give riders the option of creating a personalised set-up, rebound, as well as the high and low-speed compression settings, can all be adjusted easily by hand.
Swingarm
The swingarm is manufactured using a die-cast production process and designed with a calculated level of rigidity. To further complement and optimise the flex characteristics of the chassis, a 22 mm rear wheel axle is utilised. A durable chain slider is neatly integrated into the swingarm, ensuring uninterrupted forward momentum through deeply rutted corners.
Bodywork
The ergonomic bodywork was designed to ensure that riders can perform at their best throughout every race. This was achieved through extensive testing, with the smooth contact points in the rider triangle allowing racers to grip the machine tightly with their legs, reducing fatigue. The radiator shrouds, featuring in-mould graphics, contribute to the progressive appearance of the machine, while a tall, wide seat offers unrestricted movement. A high-grip seat cover also helps keep riders securely in place under hard acceleration.
Airbox
A strong, one-piece airbox optimises air intake by reducing deformation. This design provides an unrestricted flow of air for maximum power, without compromising filter protection. The Twin Air filter can be easily inspected without tools by simply removing the left side panel.
Hydraulic clutch
The high-performance Brembo hydraulic clutch system guarantees even wear, near maintenance-free operation, and perfect action in every condition. This means 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, and exceptional reliability of the Italian-made Brembo hydraulic system.
Hydraulic brakes
Exceptional stopping power is at hand with Brembo brakes, which feature a 4-piston, radially mounted monoblock calliper in combination with a 310 mm disc at the front. A single piston calliper and a 220 mm disc are fitted to the rear. The perfectly placed controls allow for optimal feel in all conditions while a stronger rear brake pedal provides maximum durability.
ProTaper handlebar
Developed between Husqvarna Motorcycles and leading handlebar manufacturer ProTaper, the exclusive bend offers superior comfort, class-leading strength, and fatigue resistance at the lowest possible weight.
ODI grips
ODI lock-on grips feature an innovative, integrated throttle mechanism and a glue-free installation. The throttle assembly offers easy free-play adjustment with the option to fit alternative cams for a personalised throttle action.
Footrests
New, slightly smaller footrests are low in weight and engineered to be less susceptible to scraping on the asphalt when the FS 450 is drifted through corners. The new design also ensures exceptional grip and control at every point of the race track for a confidence-inspiring riding experience.
Wheels and tyres
Black 16.5” and 17” Alpina spoked wheels on the front and rear respectively are lightweight and strong. Metzeler Racetec SM K1 125/75 R420 and 165/55 R420 slick tyres are fitted for maximum grip, traction, and agility.
Exhaust system
The exhaust system on the FS 450 features a flow-designed resonance chamber, which plays a vital role in delivering class-leading performance. Manufactured in two pieces and designed to be as compact as possible, the header pipe allows for the system to be removed without removing the rear shock. The silencer has a short and efficient design, moving weight closer to the centre of gravity and ensuring impressive power while keeping noise as low as possible. A black coating highlights its premium quality.
Cooling system
Manufactured from high-strength aluminium, the radiators are designed using Computational Fluid Dynamics (CFD) to channel air through them in the most effective way. A large centre tube through the frame reduces pressure at this point in the system for a consistent coolant flow, while an internal thermostat further enhances reliability. A reliable, threaded radiator cap allows for easy inspection of the coolant level before each ride.
Fuel tank
The 7.2-litre fuel tank integrates neatly within the ergonomic bodywork and features a strong rubber cushion beneath it to protect the frame from wear. For maximum durability, the external fuel line is specifically routed to make it less exposed and susceptible to damage. Additionally, the protective cap for the fuel filter prevents dirt and water from entering the system and shields it from impact damage.
Map Select Switch
The intuitive handlebar-mounted Map Select Switch allows riders to activate Launch and Traction Control, enable the Quickshifter, and allow riders to toggle between two engine maps. The easy-to-operate component allows for quick changes to the engine characteristics based on track conditions and rider preference.
Quickshifter
The Quickshifter can be activated or deactivated via the Map Select Switch. The function works only when upshifting, and interrupts the ignition for a fraction of a second. This allows for smooth gear changes while the throttle is fully open and without the use of the clutch. To prevent unintended shifts and false neutrals, the function is only active from second gear upwards.
Traction Control
Traction Control on the FS 450 is engaged by a button marked ‘TC’ on the Map Select Switch and functions by analysing throttle input from the rider and the rate at which engine RPM increases. If the RPM increases too quickly, the engine management system (EMS) registers a loss of grip and reduces the amount of power to the rear wheel to ensure maximum traction. This is a distinct advantage in wet and slippery conditions.
Launch Control
With the engine at idle, Launch Control is engaged by pressing the Traction Control and Quickshifter buttons simultaneously. Both symbols will start flashing to indicate that launch control is active. This function limits the amount of power to the rear wheel, improving traction, and preventing loss of control under hard acceleration. Once a gear change is made, Launch Control will deactivate automatically. Additionally, the Quickshifter is deactivated when Launch Control mode is engaged.
Mapping
For personalised power delivery, the FS 450 has two built-in engine maps as standard. Map 1 (white) offers linear, predictable power, while map 2 (green) is more aggressive for a sharper throttle response and more explosive power output.
EMS
The engine management system (EMS) is designed to be small, light, and fast at processing data. It incorporates a rollover sensor (ROS) which cuts the ignition and shuts off the engine in the event of a severe crash for an additional layer of safety.
Hour meter
The hour meter comes with an integrated fuel level indicator which is visible on the FI status LED, to clearly show when the fuel level is becoming low.
Start/stop switch
A combined start/stop switch is located on the right side of the handlebar for easy, thumb-operated use. Not only simplifying the starting and stopping of the engine, the removal of a designated stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall.
Electric start
Along with the benefit of the 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.
