I have a couple of questions on TC:

First, How the hell do you change it? I cannot select TC from the menu, it jumps over TC???? Perhaps it is because I have a bad dash like several others have noted. It does not display any data like RPM, speed, gear position, etc...

I have also read a few threads where people have claimed increased performance at lower TC settings. That would not be a good thing. How does TC work, I see a ring on the rear wheel but nothing on the front wheel?

TIA
