Regarding the use of Bell Hammer No.2 on the speedometer gear of the Honda Dax 70 (drum brake version):
Bell Hammer No.2 is a high-performance lubricant that helps reduce metal-to-metal wear while supporting smooth operation.
Therefore, it can be used on areas like speedometer gears where resin and metal components mesh.
However, please note the following:
Bell Hammer No.2 has relatively high viscosity, so for parts where rotational resistance is critical, apply it sparingly and in small amounts.
