The REKLUSE RadiusX 4.0 Clutch is an updated expanding friction disk assembly designed for select Kawasaki motorcycles. Its base material has been updated to provide better strength in high-temperature environments created by clutch systems, while redesigned internal wall bases improve strength and rigidity for a more connected lever feel.
The outside of 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 better match modern motorcycle engine characteristics, supporting more direct power delivery, improved durability and rider-focused functionality. The clutch also provides more tuning options through varying wedge weights and EXP springs. Distributor part number: RMS-8304045. Manufacturer part number: RMS-8304045.
