REKLUSE RadiusCX 4.0 Clutch, KX450F, RMS-8904044

The REKLUSE RadiusCX 4.0 Clutch is an updated expanding friction disk assembly designed for the clutch systems used in the 2016, 2017, and 2018 Kawasaki KX450F. Its revised base material provides improved strength in high-temperature environments, while redesigned internal wall bases add strength and rigidity to help deliver a more connected lever feel for the rider.

The outside of the EXP disk uses friction pads with 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 rather than sliding contact, reducing friction and resistance for smoother engagement, a more responsive feel, and stronger power delivery.

Updated engagement-curve designs are intended to better match modern motorcycle engine characteristics. The RadiusCX 4.0 Clutch also provides more tuning options through varying wedge weights and EXP springs. The distributor part number is RMS-8904044, and the manufacturer part number is RMS-8904044.

Vehicle fitment: 2016 Kawasaki KX450F, 2017 Kawasaki KX450F, and 2018 Kawasaki KX450F.
