CNC machined from 6061 T6 grade aluminium with the laser-etched Apico logo, these magnetic sump bolts are available in a range of bike-specific colours, for most 2 stroke & 4 stroke Motocross and Enduro bikes. The magnetic sump bolts help to protect the engine’s internals over time by drawing any small metal contaminants in the oil to the magnet. The sump bolt should be checked and cleaned when you change your engine or transmission oil.
