The Rekluse RadiusCX 4.0 Clutch is an updated clutch assembly for the KX450F, featuring an EXP expanding friction disk designed to provide more direct power delivery, improved durability, and rider-focused operation. Its base material has been updated to provide better strength in high-temperature environments created by clutch systems.
Redesigned internal wall bases add strength and rigidity to help deliver a more connected lever feel. Friction pads on the outside of the EXP disk use 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. Compared with sliding contact, rolling pins create less friction and resistance for smoother engagement, a more responsive feel, and stronger overall power delivery. Updated engagement-curve designs are intended to better match modern motorcycle engine characteristics, while varying wedge weights and EXP springs provide additional tuning options.
