Quite a few 6-speeds have 5th 1:1, though often times they will have a much taller final drive to make use of it, like the V160 in the Supra, which had a 1:1 5th, but used a 3.13:1 or 3.27:1 final drive.

With the 4.1 final drive and the ratios the way they are in the TL70 (6MT), it will be a very close ratio overall setup.

That's what you really need to be comparing when you're looking at other models, overall ratio. Just looking at the transmission doesn't tell you much, you need to include final drive. Obviously on the Zx6 they're all 4.1 in North America, so there's no need there, I'm just saying.
