Bonneville America Forums Forums Rider Safety Forums Helmets and Gear Gettin me a high performance hat

I believe the Halcion Mod.#64-10102 will require re-jetting when used with Triumph vertical twin engines. The also recommend KIWI polish on the bill and chin strap.

Seriously - what the hell is that? And, if it is a hat, which end is the front? I assume the strap is the bottom?
