The REKLUSE RadiusX 4.0 Clutch, manufacturer part number RMS-8301009, is designed for select Honda motorcycle applications. This updated EXP assembly uses a base material developed for improved strength in high-temperature environments, while redesigned internal wall bases provide increased strength and rigidity for a more connected lever feel.
The outside of the EXP disk features friction pads that match the proprietary friction design used on 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, reducing friction and resistance compared with sliding contact for smoother engagement, a more responsive feel and stronger power delivery.
The updated engagement curve is designed to better match modern motorcycle engine characteristics. The clutch also provides more tuning options through varying wedge weights and EXP springs, supporting rider-focused functionality, improved durability and more direct power delivery. Distributor part number: RMS-8301009. Manufacturer part number: RMS-8301009.
Vehicle fitment includes the 2017, 2018, 2021 and 2022 Honda CRF450R; the 2017, 2018, 2020, 2021 and 2022 Honda CRF450RX; and the 2020 Honda CRF450RWE.
