Jacket Armor - Good or a Waste

[Grumpy Goat]

Major points:
at low speed, armor works.
Practice not falling - bike handling skills are more important than armor.

Absolutely. On the ADV and other forums for adventure bikes like my Tiger, people are always asking about the "best" crash bars, and I have to smile because the common wisdom is that stronger is better no matter what. As if the impact load stops at the crash bar. There is always a crash load for every design, the exceedance of which will trash the bike or the engine to which it is attached. 

Same with motorcycle gear and padding. Assuming that the padding is in the right place at the time, there is always an impact load that will pass right through and break wherever is behind it. Physics (kinematics) is a wonderful subject indeed ...

I too admire Ryan FortNine for his scientific approaches which take a lot of effort to produce these videos - research as well as the video delivery. Kudos to him for not being as lazy as me.
