Husqvarna recently unveiled the 2019 FS 450 supermoto competition machine for amateur and professional racers. The motorcycle shares technology with the 2019 FC 450 motocross bike, and is built specifically to dominate on closed circuits.
The 2019 Husqvarna FS 450 gets an upgraded 450cc, four-stroke, SOHC single-cylinder engine managed by a Keihin EMS with a 44 mm Keihin throttle body. Its redesigned cylinder head compacts the power plant down by 15 mm — bringing the camshaft closer to its center of gravity, improving handling, and shaving off 500 g. The lithium-ion battery helps keep more weight off. Shorter valve timing boosts the bottom-end responsiveness of the engine, which makes up to 64 PS. It’s mated to a 5-speed PANKL Racing Systems gearbox with a Suter slipper clutch actuated by a Magura hydraulic system, handy for hard braking and motard drifting.
The new, lighter two-piece frame features improved rigidity, and its carbon fiber subframe loses 250 g of weight for 2019. The 2019 FS 450 gets 48 mm AER split-system inverted air forks, held by 16 mm offset CNC machined triple clamps, and a DCC rear shock — both by WP with updated, adjustable settings. The mean machine rides on 16.5-inch and 17-inch Alpine spoked wheels, front and rear respectively, wrapped in Bridgestone R420 slicks. Brembo brakes do the job of stopping and slowing the bike with a 310 mm front disc and four-piston caliper and a 220 mm rear disc with a single-piston unit.
On the 2019 FS 450, fuel capacity of the polythene tank reaches 7 L, seat height is measured at 890 mm, and the motorcycle weighs 102.9 kg dry. Husqvarna will be selling this bike overseas for £9,099.
