Correct about the no push button starting for the TT's. However it does have a compression release, which is used to release compression in order to rotate the engine to the correct position for starting, and has a "window" used to see a machined spot on the cam that indicates you are"safe" to attempt kick starting.
Just know that when you do kick it, you had best be serious about it. My neighbor had the first year TT, ('76), and failed to get the position correct, and spent the next several weeks in a cast when his foot/shin/ankle hit the back side of the handlebar).
But once you get to know the quirks, they are a FUN ride... Especially in the dunes.
Bought this TT new from Imperial County Yamaha (Imperial, CA) when I lived in Yuma, AZ. It is indeed a learning curve to start these without getting bit.
All that said, by comparison to more modern bikes, the suspension is ancient history, but it STILL buts a smile on my face...
