The Bell -Toptex Shorty helmet debuted in the early 1960s and was popular among motorcyclist through the end of the decade. the low profile and light nature made it a perfect helmet for roaming the cities and country roads on Triumphs, Harleys and small displacement UJMs. The helmet was Snell Memorial Foundation approved, predating DOT ratings and was very similar in style to the Buco Guardian helmets of that day. The shell extends down to about the top of the ear and a vinyl collar in connection with the chin strap secure and protect the rider from excessive wind. A variety of visors and shields were available for the front.
Still trying to figure out the role of “Toptex” in Bell helmets of this era. Originally I figured Toptex simply referred to a shell material, but in patent documents, it seems the name of the company was actually named Bell-Toptex. It seems that in the 70s the company dropped Toptex from the name and or shell material.
