2020 Husqvarna FX 450, FX 350 and TX 300i Preview & Specs

Just like the FC lineup of motocross racers, the 2020 cross-country range of Husqvarna motorcycles – the FX 450, FX 350 and TX300i – get some updates. Husqvarna has yet to release prices or availability as of this writing.

Following is what’s new in the 2020 Husqvarna cross-country lineup.

2020 Husqvarna TX 300i1. The biggest change in the 2020 Husqvarna cross-country lineup is the switch from carburetor to fuel-injection on the TX 300i. The TX 300i two-stroke motorcycle features a redesigned 39mm Dell`Orto throttle body. The four-stroke FX 450 and FX 350 models already had fuel injection.

2. The 2020 Husqvarna FX 450, FX 350 and TX 300i use chromoly steel frames that are engineered for precise flex, and a composite carbon-fiber subframe that weighs just over 2.2 pounds.

3. The cross-country lineup uses WP XACT suspension. Up front is a 48mm split-air fork with a single air-pressure valve for pre-load adjustment on the left, and 30 clicks of damping adjustment on the right. Additionally, the air pump needed to adjust the air pressure in the fork is provided as standard. The forks are paired with 22mm off-set CNC-machined triple clams to reduce vibration. Out back, the Husqvarna cross-country lineup uses a WP XACT rear shock that is pressured balanced for consistent damping.

4. The bodywork was updated for the 2020 models, not just aesthetically but to improve ergonomics. Husqvarna says the bodywork was tweaked for increased rider comfort across various riding positions. Also, the contact points to the bike were slimmed, and the seat profile redesigned for further comfort.
