1200ST - rear rotor heat question
Under normal riding conditions (street riding, not dragging the brake), how hot should I expect the rear rotor to be immediately after riding? For grins and giggles, I checked it last night after about a 20 mile in-town ride and it was literally too hot to touch with my bare finger. Up on the center stand, I notice a little drag when rotating the wheel but this is typical of any bike I've had. (This is a new bike - about 800 miles on it.)

Do not take too seriously

Pissing hot.
Think about it. You are bringing something in the order of 600 pounds to a stop only by simple means of friction on two small and thin metal discs. All that energy is being transferred into heat only.

Agreed.
But if you're concerned, drive the last few miles home w/o using the rear brake. If it's still hot, THEN you have an issue (dragging) Otherwise, you're fine.

You will recognize drag immediately, as the wheel will stop almost instantly if you give it a swirl on the stand. And the disc will be blue. Which is ok if you have been playing hard and been hard on the brakes, but under normal conditions it is an indicator of something being not entirely right.
