The REKLUSE RadiusCX 4.0 Clutch is an updated expanding friction disk assembly designed for select Honda CRF450 models. Its base material is updated to provide improved strength in high-temperature environments, while redesigned internal wall bases enhance strength and rigidity for a more connected lever feel.
The outside of the EXP disk uses friction pads that match the proprietary friction design found on REKLUSE TorqDrive clutch plates. This design matches oil-flow characteristics within the clutch pack beneath, promoting improved cooling capability and consistent operation. EXP 4.0 wedges 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 assembly also provides more tuning options through varying wedge weights and EXP springs, supporting direct power delivery, improved durability and rider-focused functionality.
