And when you had an engine fire, these things burned spectacularly.
Heeeey, I've seen this story before somewhere! https://www.automobilemag.com/news/2...rns-in-desert/

I have magnesium alloy wheels on my car and after 7 years they started showing signs of corrosion, surprisingly in some spots that weren't scratched. Your bike catching on fire is not likely, but corrosion from multiple dings and scratches, I wonder how long-lasting that finish is.

Non-flammable magnesium alloys have been a thing for some time now, but it would make a cool YouTube video.

Good to know. Again, tech saves the day and I'm feeling older.
