The REKLUSE RadiusX 4.0 Clutch for the KX450F features an updated EXP expanding friction disk assembly designed to provide more direct power delivery, improved durability, and rider-focused functionality. Its base material is updated for better strength in high-temperature environments created by clutch systems, while redesigned internal wall bases add strength and rigidity for 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 within the clutch pack, 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, a more responsive feel, and stronger power delivery.
The engagement curve has been updated to better match modern motorcycle engine characteristics. The REKLUSE RadiusX 4.0 Clutch also provides more tuning options through varying wedge weights and EXP springs. Manufacturer part number: RMS-8304046. Vehicle fitment: KX450F.
