I've seen people claiming that only super low level wyverns can be tamed without primal crystals, but that simply isn't true.

All you have to do is jump on their back (can be done from the ground), center yourself up where the wings meet the neck, start pumping it full of regular old crystals, and enjoy the ride. I tamed 4 of them that way today, and not once did I get thrown off or have the progress bar start to drop.
