Husqvarna FS 450

With refined technical enhancements, the 2026 Husqvarna FS 450 continues to stand out as the ultimate purpose-built Supermoto machine on the market. Its modern engineering is crafted to deliver an exceptional, track-focused ride for dedicated supermoto riders. 

The heart of the FS 450 is a lightweight SOHC engine (just 26.8 kg) that’s centrally positioned to optimise mass centralisation and improve handling balance. The engine benefits from a compact design, with camshaft placement as close to the centre of gravity as possible to enhance agility. Its low-friction cam chain runs on precision guides, and a single oil spray jet ensures efficient cooling.

Twin engine maps, along with Launch Control and Traction Control (accessible via a handlebar-mounted Map Select Switch), allow riders to tailor performance to track conditions. A Quickshifter, integrated via the shift drum, offers seamless upshifting. The Pankl 5-speed gearbox uses optimised gearing (29:72) while the Suter anti-hopping clutch keeps rear wheel chatter in check under aggressive braking. Electric start is provided by a Li-Ion 2.0 Ah battery, saving weight without compromising reliability.

The 2026 model retains the central double-cradle 25CrMo4 steel frame, but with an improved material layout around key junctions (steering head and upper shock mount), delivering both cornering precision and straight-line stability. A two-piece, polyamide-reinforced aluminium subframe keeps weight low (just 1.8 kg) while contributing controlled flex characteristics. Triple clamps are CNC-machined and let riders select rubber-damped or fixed mounting for tuned front-end feel.

Suspension is upgraded with WP XACT 48 mm closed-cartridge forks, now offering 283 mm of travel. A hydrostop system ensures bottoming resistance in the final 68 mm of travel, while rebound and compression damping are user-adjustable. The rear WP XACT shock retains 266 mm of travel and features a CFD-optimised main piston to balance plushness and responsiveness, with independent high- and low-speed compression and rebound adjustment. The die-cast swingarm is tuned for progressive rigidity, using a 22 mm rear axle and integrated chain slider to ensure smooth traction and flex control. 

Braking duties remain uncompromising, led by Brembo radial 4-piston calipers with a 310 mm front disc and a 220 mm single-piston rear disc. The hydraulic Brembo clutch is designed for even wear and minimal maintenance, maintaining consistent feel across conditions. Slimmer, lighter footrests reduce the chance of asphalt strikes during aggressive slides, while providing strong grip. Updated ergonomic bodywork—with refined radiator shrouds, in-mould graphics, and a tall, wide seat—ensures freedom of movement and a confident rider triangle. An improved one-piece airbox minimizes deformation and maximises airflow; the Twin Air filter is tool-free to inspect.

For 2026, the FS 450 rolls on lightweight Alpina spoked wheels (16.5″ front, 17″ rear) fitted with Metzeler Racetec SM K1 slick tyres (125/75 R420 front, 165/55 R420 rear) for exceptional track grip and agility.

An optimised two-piece exhaust with a compact silencer helps keep mass central and noise emissions restrained. Radiators, designed via CFD, improve airflow and cooling efficiency, aided by an internal thermostat and smart frame routing. The 7.2 L fuel tank is cushioned to protect the frame and features protected routing for external lines.

Overall, the 2026 Husqvarna FS 450 combines refined chassis architecture, advanced electronic control, and race-focused componentry to maintain its status as Supermoto’s benchmark machine.
