Press Release | September 23, 2020
Husqvarna Motorcycles releases the 2021 FS 450, a single-cylinder competition supermoto machine.
Here is the press release from Husqvarna:
Underlining the brand’s continued commitment to the supermoto segment, Husqvarna Motorcycles North America, Inc. is pleased to announce the release of the MY21 FS 450–the single-cylinder competition supermoto machine that features advanced engineering, class-leading ergonomics and traction control as standard.
Housing a compact–yet powerful–engine within a lightweight frame and modern bodywork, the FS 450 features revised suspension settings that deliver enhanced handling and damping characteristics for incredible on-track riding experiences.
For 2021, the FS 450 features WP Xact forks with AER technology and a new mid-valve damping system that ensures a more consistent front-end suspension performance. Further enhancing the machine’s maneuverability, a new 22 mm diameter front axle and a 7 mm reduction in the base offset of the forks sharpens turning and overall agility. Refinements to the easily adjustable WP Xact shock improve rear-end damping performance with new, low-friction linkage seals delivering a refined suspension response.
Firing into life with a simple press of the electric start button, the FS 450’s SOHC engine provides riders with responsive and usable power, delivered smoothly through the Pankl Racing Systems five-speed gearbox.
The FS 450’s functional bodywork delivers ergonomics designed for exceptional comfort and is further enhanced by the addition of a high-grip seat cover to improve control in all conditions.
Enabling balanced and powerful braking, a 4 piston radially-mounted Brembo brake caliper and master cylinder work in conjunction with a 310mm disc to deliver exceptional front-wheel stopping performance. A single-piston brake caliper and a 220mm disc are mounted at the rear for balanced control.
The FS 450 features premium components, including CNC-machined triple clamps, Alpina wheels and Bridgestone tires, a carbon-fiber composite subframe and a Magura hydraulic clutch, ensuring unrivaled, top-level supermoto performance.
