Husqvarna has unveiled its full lineup of 2019 cross-country bikes with the FX and TX models. The updates made to the off-road bikes are, for the most part, similar to the changes made to the FC and TC motocross models featuring several engine, suspension, and chassis updates.

Engine

All of the engines receive unique changes per each model. The FX 450 features a new SOHC cylinder head 15mm (approximately 0.6 inch) shorter and 500 grams (1.1 pound) lighter, and a new camshaft with a different surface material. The FX 350 has an updated casting on the cylinder head for a weight saving of 200 grams (approximately 0.4 pound), larger titanium valves (36.3mm intake and 29.1mm exhaust), and a new Diaphragm Steel (DS) clutch saving 190 grams (approximately 0.4 pound) of weight. The TX 300 has a new muffler and different engine covers with better resistance to wear.

The FX 450 and FX 350 share a few of the same updates including different header pipes with a new integrated flow-designed resonance chamber and a new joining position, allowing them to be removed without detaching the shock. Two other changes made to the four-strokes are shorter and more compact mufflers, and updated traction and launch control settings. All three bikes (two-stroke and four-stroke) have new-generation lithium-ion batteries, Pankl transmissions, and updated cooling systems with a new center tube.
