The REKLUSE RadiusX 4.0 Clutch is designed for the XR650R and features an updated EXP expanding friction disk assembly. Its base material is updated for improved strength in high-temperature environments, while redesigned internal wall bases provide increased strength and rigidity for a more connected lever feel.
The 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 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 provides more tuning options through varying wedge weights and EXP springs, supporting more direct power delivery, improved durability, and rider-focused functionality. The manufacturer part number is RMS-8301019, and the distributor part number is not provided in the product data.
