Rekluse introduces an all new type of clutch system that can be configured in two different operating modes: manual mode or anti-stall mode. The Rekluse Core Manual Clutch consists of a center clutch, a matched set of steel drive plates, springs and a manual pressure plate. The Rekluse Core EXP Clutch consists of a center clutch, a matched set of steel drive plates, springs, an EXP friction disk and an EXP pressure plate. All Rekluse Core Clutches work with your bike's stock friction disks or Rekluse friction disks. One of the primary benefits to the Rekluse Core Clutch is the ability to change from anti-stall mode (Core EXP Clutch) to manual mode (Core Clutch) in a matter of minutes.
