Okay, I answered my own question. Don't know why I didn't see this when I looked yesterday, but there is a T-Dub specific unit number 75-201.

There is no model specific to the T-Dub and the generic items are for water cooled+disk brake or air cooled + drum brake. They make one for the TT-R125L which is air cooled and has a disk, wondering if this might be the best choice to make all the features work. Still may have to fab-up a mounting bracket for the speedo etc, but . . .???
I have had of these mounted on my TW for over 3 years now. Works perfectly, very easy to install and overall I am very happy with it. Rememeber you need to buy the extra casing that goes around it to hook up your pilot lights. (Neutral, high beam and indicator)
Yes it's a full custom Tdub, check my sig for build pics![]()
