Rekluse RadiusCX 4.0 Clutch for Honda CRF450X (RMS-8901013)

Upgrade your Honda CRF450X with the Rekluse RadiusCX 4.0 Clutch, part number RMS-8901013. This updated EXP assembly is engineered to deliver more direct power transfer, smoother engagement, and consistent operation in demanding riding conditions. The revised base material provides improved strength in the high-temperature environment created by modern clutch systems, while redesigned internal wall bases increase strength and rigidity for a more connected lever feel.
The outer EXP disk features friction pads based on Rekluse’s proprietary TorqDrive clutch plate design. This friction design helps align oil-flow characteristics with the clutch pack beneath, supporting improved cooling capability and dependable performance throughout extended use. The updated engagement curve is designed to better complement modern motorcycle engine characteristics, helping provide predictable clutch response and stronger power delivery across a wide range of riding conditions.
EXP 4.0 wedges now use rolling contact with integrated pins rather than sliding contact. This design reduces friction and resistance within the assembly, contributing to smoother engagement and a more responsive feel at the lever. The RadiusCX 4.0 offers additional tuning flexibility through available wedge weights and EXP spring options, allowing riders and technicians to adjust clutch behavior to suit riding style, terrain, and engine performance. Built for riders seeking improved durability, refined control, and rider-focused functionality, the Rekluse RadiusCX 4.0 is a high-performance clutch upgrade for the Honda CRF450X.
