The largest-displacement off-road competition motorcycle from Husqvarna is the FX 450. Although it shares many of its components with the FC 450 motocross bike, the FX 450’s softer suspension settings, larger 2.25-gallon fuel tank, 18-inch rear wheel, kickstand, and Dunlop Geomax AT81 tires make it more suitable for cross-country racing.

2020 Husqvarna FX 450 Reviews, Comparisons, And Competition

Since it was first introduced in 2017, we have tested, dyno’d, and compared the FX 450 against others in the 450cc four-stroke cross-country motorcycle segment. In our review of the 2020 model, test rider Allan Brown had plenty of good things to say about the bike: “The FX 450’s strengths are plenty of smooth and usable power, precise handling, a lightweight feeling, and great ergonomics.”

Its competitors include the 2020 KTM 450 XC-F, 2020 Yamaha YZ450FX, and 2020 Honda CRF450RX. With its suggested retail price of $10,699, the FX 450 costs $100 more than the 450 XC-F, $1,100 more than the YZ450FX, and $1,000 more than the CRF450RX.

Husqvarna FX 450 Updates For 2020

New graphics are the only change the FX 450 received for 2020, but the bike was heavily updated the year before with a stiffer frame, updated suspension settings, and a shorter and lighter cylinder head.
