We worked with Dimple drain plug magnets to develop a low-profile replacement drain plug for the Yamaha Super Tenere and the Honda Africa Twin. On the Super Tenere in particular, the sump drain plug is very exposed and susceptible to damage.
The OEM plug has a 15mm head height and hangs precariously off the side of the engine and the tall head height is just waiting to be smacked and crack the pan. Our special low-profile head is only 5mm tall. In addition to typical hex head, we have an internal broach for a 6mm allen tool. This helps prevent over tightening and also gives two options for what you carry in your tool kit. A magnetic drain plug attracts small ferrous particles circulating through your engine which could otherwise cause damage. An increase in the amount of particles picked up can signal if there is a more serious internal problem with your engine.
All magnets are not created equal. We use N48SH Neodymium (“rare earth”) magnets. The N48 refers to the magnetic strength, while the SH super high temperature rating. This is important as you are installing this into an area of heated engine oil, and we want them to still work! Standard neodymium magnets start to lose their magnetism at 176°F (80°C). The “SH” temp rating has an operating temp of 302°F (150°C), much more appropriate for use on internal combustion engines.
The magnets are fitted into the end of a machined recess at the plug tip. Our plugs are made from steel for strength and also because the magnet sticks in place. For additional precaution we also apply epoxy to keep the magnet in location. Other drain plug magnets made from aluminum or stainless steel rely on a press fit which can change as the different materials expand and contract differently with heat cycles. The plug is lastly coated with a special 2-step super corrosion resistant coating developed for use in the harsh environment of off shore oil rigs.
We think these are the absolute best drain plugs you can get for your motorcycle, look for more sizes and fitments coming soon, or contact us for your specific need.
