For 2021, Husqvarna focused on dialing in its WP suspension package. The FC model bikes have a 10 mm shorter fork, and a new linkage out back to lower the bike 10 mm as well. When asked, the WP suspension techs explain that the goal of having a slightly lower bike overall is to help with staying planted in the corners, specifically mid-corner stability. They also explained that the new linkage is designed to keep the same shock characteristics as last year’s bike, just with 10 mm less travel.
In addition, the 2021 FC 450’s engine maps were updated, with the goal of having map one smooth and linear, and map two aggressive across the board. This is in contrast to last year’s maps which some testers felt map one had stronger bottom-to-mid power, and map two had stronger mid-to-top power.
