I've counted the teeth on the BMW Hp2 Sport drive-gear and there are 58 teeth with a gap where two are missing.

Can anyone help me with the right terminology. It is termed a 58-2 or a 60-2?

Cheers

Hi there.
According to the Megasquirt website it will be a 60-2.

Ta!

If there weren't 2 missing, would it have 60 teeth? If so, 60-2

60 -2 defo
