What is this?

If you look outside the clutch you can (or I can ) make out a brake band, looking at the left side of pic 1 it is more noticeable. Surrounds entire disc (flywheel/rotor).

The trans appears to only act as a gear ratio reducer and reverser.

Thanks, now I have to decide If I actually want it. The seller has mentioned that the motor runs but sound like it is going to pile, everything else works good. What would you guys pay for this? I know the asking price but do not want to sway your opinions
