This is an oil drain plug that has a very strong magnet in it that will grab all of those large & small metal flakes that float around in every engine oil. It is just one more way to safeguard against engine damage. This bolt fits the following models.

RM80 1986-2001
RM85 2002-2012
RM125 1992-2006
RM250 1993-2006
RMX250 1989-1998

All of these models should have a 12mm x 1.25 thread pitch bolt, please make sure your model takes that bolt.

Free shipping is in the U.S only. Thanks
