Corrosion on our bike.

Already 2500 year, the human being tries to describe the destructive forces of corrosion. Herodotos wrote: “ Ferrum corumpitar”.
And yes, that is the natural behavior of metal. We dig the ores out of the earth. We extract the metal from the ores by adding a huge amount of energy. We make some beautiful constructions with it, like our Royal Enfield. It is hard to believe but this valuable metal structure of us wants to go back to its natural state: the ore, the oxide. It corrodes.
But, the human being is curious. We observed, corrosion only takes place when metal is in contact with an electrolyte.  A conductive liquid so to say:  Hmm…water thus.
So, how to prevent corrosion? Simple: exclude the metal from contact with water.

The obvious ways of doing:
Cover the metal with a coating or paint. A good paint is by definition non permeable and non-conductive. But every coating will be permeable after some time and then….corrosion starts.

What the duck!
Ever tried to wet a duck? Difficult he? Well this duck learned how to stay dry. It oils his feathers and… water has no impact on greasy or oily materials.  So, back to our beloved metal duck: make sure to oil everything.

As oil disappears, bit by bit in contact with water, wax might be a more durable alternative to the oil or grease.

Crevice corrosion.
The killer behind the corner. And looking at corners and small hidden openings…there are plenty of them.
Some examples:

  • the space between a washer and a nut,
  • the bend edge of a mud guard,
  • the space between two joined plates.

These are small cavities, in which some water can accumulate. It forms like a micro-environment with an own activity called: corrosion! Fill these spaces with a water repellent mass like wax or grease and corrosion gets no chance on your bike.


One thought on “Corrosion on our bike.

  1. I have a bullet 350 machismo dating back from 2004. It has a lot of chrome parts. Non of those showed any corrosion after 10 years of daily commuting. It’s an Indian local market product. My bullet 500 from 2015 however, shows considerably more corrosion after barely 2 years. This is an export product!!!. What happened to the Royal Enfield chroming process??
