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.
