New upgraded front sprocket nut.
YAMAHA changed thickness from 8 mm to 12 mm - what prevents nut from unscrewing or damaging thread.
The thread is nominally 18 mm in diameter, with a pitch of two threads per 1 mm (M18x1 mm).
Substitute of OEM part no.: 90179-18006
The same quality as OEM - made of the same sort of steel and in the same technology.
