In the initial Season 4 update, we added the 'Pro MX 450F Experimental' class bike, which will serve as a testing ground for our gameplay and physics team. Our goal with this physics set has been to put testing into the hands of the community so we can get feedback directly from you, then incorporate it into each new iteration until we find the ideal pro physics gameplay. We opened an #experimental-physics channel in Discord, where the devs and players can speak directly, about how the bike feels, and have been watching your comments on social media. The level of community participation has completely blown us away, and we are excited about the direction the experimental physics are heading.
We heard tons of requests to let you ride your favorite factory bikes with the new physics, so as of v4.03 we have added Pro 450F Experimental variants to all 2025 OEM 450F models. Another piece of feedback was that the bike felt much too heavy in the air, making it difficult to whip and maneuver. While the Experimental physics set needs its own unique feel, we recognize that part of what makes Legends base gameplay physics so fun is that the bike has a certain flicky feeling in the air that lets you really toss the bike around. So, to help capture that feeling, we have slightly lowered the weight of the bike and made it a little easier to toss around in the air. Changes to braking have also been made, which will make the bike less likely to lock up when hard braking into turns. Wreck thresholds have also been touched up a bit so that you are less likely to crash on a 'hard landing'. We still have TONS of work to do on the new physics, so more changes will be coming in the next update. Make sure you let us know how you feel about v4.03's changes in our Official MX vs ATV Discord, so that we can keep pushing forward together!
