The REKLUSE RadiusX 4.0 Clutch, manufacturer part number RMS-8302122, is an updated EXP assembly designed for improved strength and consistent operation in high-temperature clutch environments. Its redesigned internal wall bases provide added strength and rigidity, helping deliver a more connected lever feel for the rider.
The EXP disk features friction pads based on the proprietary friction design used in REKLUSE TorqDrive clutch plates. This design matches oil-flow characteristics within the clutch pack to promote improved cooling capability and consistent operation. Updated 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 more direct power delivery.
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. The REKLUSE RadiusX 4.0 Clutch fits the 2022 Beta 300 RR; 2022, 2023, and 2025 Beta 250 RR models including Race Edition versions; 2022 Beta 250 RR-Race Edition; 2023 Beta 300 RR; 2025 Beta 250 Xtrainer; 2025 Beta 300 RR X-Pro; 2025 Beta 300 RR-Race Edition; and 2026 Beta 250 RR X-Pro.
