Suter slipper clutches are some of the best on the market.  With vast experience in WSBK, MotoGP, and Moto2 racing, their products are trusted by some of the fastest teams on the planet.

This spring allows you to fine-tune how much your Suter clutch will slip when under reverse torque.  Higher rate springs will have less slip, and conversely lower rate springs will have more slip. This spring does not affect the overall clamping force of the clutch.
