They groom the tracks for safety, not social media, and it's not so that the riders have "pristine" conditions. Other than water (On the Supercross test tracks), they often do nothing with the tracks! The thing you need to remember is that test tracks don't have 300+ riders of all classes tearing the shit out of it, and they're not just there to practice, but to also test in a controlled environment with data that is gathered constantly.Because we're headed out of Supercross season, most right now are maybe thinking of images of those tracks, but when they are practicing at say Glen Helen, they are still at the mercy of the same track conditions as anyone else, which are public tracks so to speak, so they are groomed as said before, for safety!That being said, like loftyair said, a lot of them show up early, before it gets too hot, or sometimes the teams rent the tracks for a while, either way they aren't as rough looking as at the end of a raceday. I would say to jump out there if you have never been, and tell me if you still think the tracks are always as smooth looking as you think in pics compared to real life, LOL!Most of the big tracks are never groomed like your local freeway looks on raceday morning!
