Which Material is Best for Gear? Abrasion Resistance Tests

[gfloyd2002]

There are many choices when selecting motorcycle gear, and we hear things about which materials provide best protection against road rash. I thought some research might benefit those looking for gear, or people who sometimes don't wear all their gear. The following comes from manufacturers, individual tests from advrider.com and various other sources, but they should provide some good points for discussion and probably offer good rules of thumb. Please note that abrasion resistance is only part of the story, you should also consider stitching quality and impact protection. If you have good abrasion resistance, but the stitching fails, you may end up using skin as your abrasion resistance. Also, if you have a poor fit of you gear, it may shift, making abrasion resistance worthless. Please also note that there are a couple of studies that show that price and protection aren't necessarily linked. You have to check quality, not the brand.

I'll edit this OP as I finish research and it may end up significantly changed -- there are a few good European studies still out there I'm trying to get, and I'll draw some conclusions. So far, these studies tend to be a bit old, and don't include enough information about modern, high D corduras. I'm also welcoming reference to additional studies I can report here.

At bonniville they are very conserned with abration resistance. Sliding on salt at 200 mph plus will test your gear. They ONLY allow leather.non perferated with metal zippers. Not the best choice for most street riding but I thought I would mention it
