Fewer Brains Please!!
I know that when I went from an old car with rear-wheel drive to a new car with front-wheel-drive, traction control, and ABS, I thought it was a step down. Driving my old bike in the rain may require a bit more concentration, but it also connects me to the machine in a way driving on dry pavement cannot. I can feel every squirm and sqigle of the rear tire, and every scoot of the front. So, in my opinion, traction control would be a step backward for the motorcycle industry. Who here wants that vague, disconnected feeling on a bike? I know I don't.
