The REKLUSE RadiusX 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 improved strength in high-temperature environments, while redesigned internal wall bases add strength and rigidity to help create a more connected lever feel.
The outer EXP disk uses friction pads that match the proprietary friction design found on REKLUSE TorqDrive clutch plates. This design helps match oil flow characteristics within the clutch pack, promoting improved cooling capability and consistent operation. EXP 4.0 wedges now use rolling contact with built-in pins, reducing friction and resistance compared with sliding contact for smoother engagement and a more responsive feel.
Updated engagement curve designs are intended to better match modern motorcycle engine characteristics. The clutch also offers more tuning options through varying wedge weights and EXP springs.
