This past 2018 Monster Energy Supercross season, Husqvarna took home both the 450 and 250 East Regional Championship Titles, as well as the 2017 250 Lucas Oil Pro Motocross Championship. Clearly, Husqvarna is onto something and is building some of the fastest and best handling dirtbikes money can buy. So, how do you take already great performing machines and make them even better?
Good question. We’re glad you asked, because we’re curious too. Basically, Husqvarna shaved weight off wherever possible. The bodywork is completely new and redesigned, which thinned the bikes out, the cylinder heads are recasted, weighing up to 500g less, the carbon composite subframe is lighter than before, shaving over two pounds, and there’s a new integrated cooling system that uses the frame as a part of the whole setup. Even the radiators were redesigned to not only help cool the coolant more effectively, but they were also repositioned closer to the bikes’ center of gravity.
In the chassis and handling department, certain areas of the frame were reengineered for more optimal torsion, the triple clamps have been reshaped and stiffened to work in concert with the increased longitudinal rigidity of the frame, and the WP AER 48 front fork and rear shock received updated valving and settings adjustments. The four-stroke models feature variable fuel-map selection as well as traction control – yes, traction control – to help the rider optimize power output and wheel spin depending on the conditions.
Additionally, a lot of the bikes’ components have been reengineered to help make working on and servicing easier. These are just a few of the highlights, but for the full detailed description, Husqvarna lays it all out below.
