Rekluse RadiusX 4.0 Clutch for Honda CRF450R (RMS-8301010)

Upgrade your Honda CRF450R with the Rekluse RadiusX 4.0 Clutch, part number RMS-8301010. This updated EXP assembly is engineered for improved strength, smoother engagement, and more consistent clutch operation in demanding riding conditions. Its redesigned friction disk and internal wall bases help withstand the heat generated by high-performance clutch systems while delivering a more connected lever feel and dependable power transfer.
The outer EXP disk uses friction pads based on Rekluse’s proprietary TorqDrive clutch plate design. This helps match oil-flow characteristics within the clutch pack, supporting improved cooling capability and consistent operation during aggressive riding. The updated EXP 4.0 wedges use rolling contact with integrated pins rather than sliding contact, reducing friction and resistance for smoother engagement, faster response, and stronger overall power delivery.
The RadiusX 4.0 Clutch also features revised engagement-curve designs developed to better complement modern motorcycle engine characteristics. Riders benefit from improved durability, direct power delivery, and tuning flexibility through available wedge-weight and EXP-spring combinations. Designed specifically for the Honda CRF450R, the Rekluse RMS-8301010 provides rider-focused clutch performance for motocross, off-road, and other demanding applications.
