For anyone who changed their front sprocket on a 2020+ MT03 recently what's the exact size socket for the nut?

I've seen 29mm, 30mm, and 1 1/8".

29 mm - https://www.r3-forums.com/threads/415-chain-and-sprockets.86922/ "Started my conversion tonight and realized I don't have a 29mm socket"

1 1/8" - https://www.r3-forums.com/threads/front-sprocket-nut-torque.127210/?post_id=490930&nested_view=1#post-490930 "the nut is 29.5mm measured with verneir calipers. so its an imperial nut so the correct size IS 1-1/8 Socket "

Google says it's 30 mm.

Partzilla has the part but doesn't list the size (part # 90179-20013-00) https://www.partzilla.com/catalog/yamaha/motorcycle/2022/mt03-mt03ngy-b5wd0/transmission
