When your bike explodes don't store it, run to a player city a few thosand meters away and enter a house, disconnect and connect again then when you connect, call your bike and it should be at perfect condition, this works with both condition loss, pvp, and pve.
now this worked for me only a few times, im not sure if this is just a bug that will be fixed or not here it is
Take any customization tool, select the customization you would like to make and change it to whatever color you prefer but dont close the tool, just open your inventory and reopen the tool again and now press cancel
