The REKLUSE RadiusCX 4.0 Clutch is an updated expanding friction disk assembly designed for select Beta motorcycles. Its revised base material provides improved strength in the high-temperature environments created by clutch systems, while redesigned internal wall bases increase strength and rigidity for a more connected lever feel.
The outside of the EXP disk uses friction pads matching the proprietary friction design found on REKLUSE TorqDrive clutch plates. This design helps 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 are intended to better match modern motorcycle engine characteristics. The clutch also provides more tuning options through varying wedge weights and EXP springs, supporting direct power delivery, improved durability and rider-focused functionality.
