Were any early single 4 speed roadsters sold new in the late 1950's with close ratio boxes ?, were parts availiable to convert ?.

The first 175s had a closer ratio transmission, but they're hard to find, and the F3, but not really a 'roadster'- will attach part of an old spreadsheet that I think is accurate.

Thanks Rick, I will pass that on , Do you think that later 175's had wider ratio boxes than the early 1957 bikes. ?.
