The REKLUSE RadiusX 4.0 Clutch is an updated expanding friction disk assembly designed for select Kawasaki motorcycles. Its base material is updated for improved strength in high-temperature environments, while redesigned internal wall bases provide greater strength and rigidity for a more connected lever feel.
The outer EXP disk uses friction pads that match the proprietary friction design found on REKLUSE TorqDrive clutch plates. This design is intended to match oil-flow characteristics in the clutch pack beneath, promoting improved cooling capability and consistent operation. EXP 4.0 wedges now 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. 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-8304003. Manufacturer part number: RMS-8304003. Fits 2017, 2018, 2019, 2020, 2021 and 2023 Kawasaki KLE300 Versys-X 300 models, including listed ABS applications, and 2013, 2015 and 2017 Kawasaki EX300 Ninja 300 ABS models.
