Recent scooter trip to the UP of Mich, crossed Mesh surfaces three times, Mackinac Bridge ( quite long), did same bridge in Houghton (short) twice.
Really gets your attention on scooter that has rear weight bias and has high load--- just replax and let scooter move around---death grip on bars=possible killer. Been over these bridges on real motorcycles in the past with no trouble, and on other scooters, my point here is it takes much more skill to ride scooter than motorcycle---scooter has no pegs to stand on/tank to grip.
Been on these same bridges with Helix/Reflex/Burgman 400/SilverWing 600---XTown 300i really attention getter for me. Maybe tire combination?
