The REKLUSE RadiusX 4.0 Clutch is an updated expanding friction disk assembly designed for selected Yamaha YZ250 and YZ250X motorcycles. 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.
The outside of the EXP disk uses friction pads with the proprietary friction design found on REKLUSE TorqDrive clutch plates. This design matches oil flow characteristics within the clutch pack beneath it, promoting improved cooling capability and consistent operation. EXP 4.0 wedges use rolling contact with built-in pins instead of sliding contact, reducing friction and resistance for smoother engagement and a more responsive feel.
Updated engagement curve designs are intended to better match modern motorcycle engine characteristics. The assembly also provides more tuning options through varying wedge weights and EXP springs, supporting direct power delivery, improved durability and rider-focused functionality. Distributor part number: RMS-8307070. Manufacturer part number: RMS-8307070.
Vehicle fitment includes the 2009, 2010, 2015, 2016, 2018, 2020, and 2023 Yamaha YZ250, plus the 2016, 2018, 2020, and 2021 Yamaha YZ250X.
