A use for old motorcycle helmets?
Motorcycle helmets are pretty expensive, but they're cheaper than a new brain. So, I've always used good helmets in good condition.
After crashing I have helmets that may not be safe to use. So I sent them to Shoei to have them X-Rayed. They use the latest in radiation technology to actually peer inside the helmet & see if it's structurally damaged.
The helmets came back with a note saying they were over 7 years old, and should be replaced.
Now what do I do with old helmets? Is there anything more useful for them than propping up the next layer of trash in a landfill?
