Husqvarna FS450 2025 Introducing the Husqvarna FS450 2025 Starting From £11,249.00

FS450 2025

BUILT FOR COMPETITION

Significant technical updates for 2025 ensure the FS 450 easily maintains its position as the leading purpose-built Supermoto machine on the market. The modern machine is powered by a versatile SOHC engine that creates a broad spread of controllable power, which can then be customised by engaging various electronic rider aids including launch control, traction control, and a choice of two engine maps. A revised frame and new engine mounts combine to deliver a calculated level of chassis flex for improved handling with high-speed stability assured. WP XACT forks are fitted to this competition-focused motorcycle for the first time to boost comfort and agility while the new footrests, linkage seals, air intake, radiator shrouds, and a revised swingarm ensure the riding experience of the FS 450 is taken to an even higher level for 2025.

FROM £11,799.00

ENGINE

The FS 450 engine benefits from advanced engineering techniques to deliver maximum performance. Weighing just 26.8 kilograms, and is tilted two degrees backwards to further centralise mass for enhanced handling and significantly improved anti-squat behaviour from the chassis. Servicing of the FS 450 engine is made easier compared to previous models thanks to the addition of service markers on the engine cases.

GEARBOX

Produced by Pankl Racing Systems, the 5-speed gearbox is designed to be extremely light and durable while featuring an optimised and proven gear ratio (29:72). A redesign of the shift shaft reduces the operating forces required for gear changes. Integrated into the shift drum, a new Quickshift sensor can be activated by pressing the QS marked button on the map select switch to further aid seamless upshifting.

Anti Hopping Clutch 

Featuring a Suter anti-hopping Clutch to prevent rear wheel instability and hopping when breaking hard into the apex of a turn for total control and perfect drifting. It reduces the physical effort needed by the rider and improves Lap times. ​

MAP SWITCH

A intuitive handlebar-mounted map select switch allows riders to activate launch and traction control, enable the new Quickshift functionality, and allows riders to toggle between two engine maps. The easy-to-operate map select switch allows racers to quickly alter and set up the engine characteristics on a race by race basis dependent on track conditions and rider preference.

CNC MACHINED TRIPLE CLAMPS

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 is stiffer to ensure a smoother fork action and plays a vital role in the perfect alignment of the front wheel for superior handling.

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. 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. 

FRAME

The proven chromium molybdenum steel frame significantly improves the anti-squat behaviour of the chassis. With optimised wall thickness in high stress areas improving reliability, the frame continues to offer advanced geometries and flex characteristics aimed at providing unparalleled rider feedback, energy absorption, and exceptional straight-line stability. The frame is finished off in a premium metallic blue powder coating with redesigned standard frame protectors offering superior protection, durability, and grip in any condition.

BODYWORK

Clean, Swedish-inspired design and ergonomics are tailored to allow riders to perform at their best for extended periods of time. Adapted after countless hours of testing, the contact points and surfaces in the rider triangle have been repositioned to improve comfort on the motorcycle. A new, flatter seat offers unrestricted movement with a high grip cover ensuring riders stay firmly in place under hard acceleration.

WP XACT SUSPENSION

The 48 mm split air forks now offer improved bottoming resistance thanks to a new hydrostop, which applies a progressive damping force in the last 40 mm of travel for even greater comfort. The WP forks are designed with a capsulated, adjustable air spring and pressurized oil chamber for smooth action and consistent damping. Oil and air bypasses reduce pressure peaks and in combination with a midvalve damping system, the forks provide precise feedback to the rider. The settings are easily adjusted via the single air pressure pre-load valve, as well as through easy access click adjusters for compression and rebound. Additionally, the air pump needed to adjust the fork's air pressure is provided as standard.
