The REKLUSE RadiusCX 4.0 Clutch is an updated expanding friction disk assembly designed to provide more direct power delivery, improved durability, and rider-focused functionality. Its base material is updated for increased strength in high-temperature environments, while redesigned internal wall bases improve strength and rigidity for a more connected lever feel.
The EXP disk features friction pads based on the proprietary friction design used in REKLUSE TorqDrive clutch plates. This design matches oil-flow characteristics in the clutch pack beneath, promoting improved cooling capability and consistent operation. EXP 4.0 wedges use rolling contact with built-in pins instead of sliding contact, reducing friction and resistance for smoother engagement, a more responsive feel, and stronger power delivery.
Updated engagement curve designs better match modern motorcycle engine characteristics. The clutch also provides more tuning options through varying wedge weights and EXP springs.
