The piece at the top? That's the spring...but it's not entirely new. Hinson has been using a similar setup in their slipper clutches for quite a while with good results.

Have you heard about the most recent clutch setup from Hinson? Rather than loading up the traditional 4-6 springs (which need to be carefully matched to keep the inner hub and pressure plate aligned and working smoothly), they’ve adopted a single spring. This setup is claimed to eliminate drag between the springs and the inner hub/pressure plate for a smother action, and the single spring design helps reduce heat since it lays flatter and prevents clutch drag.
