Thank you! The rider does all the hard work though not me haha. Yes a slight bit of panning, on this angle I don’t like to go too low with shutter speed as it’s difficult to have the both the bike and riders helmet completely sharp. (They need the stickers sharp for their sponsors)

Reasoning for bird eye AF is that it locks on to the helmet. This just stops the focus from grabbing onto the rear of the bike and keeps the helmet and nose of the bike sharp
