Rekluse RadiusX 4.0 Clutch for Honda CRF450R (RMS-8301011)

Upgrade your Honda CRF450R clutch performance with the Rekluse RadiusX 4.0 Clutch, part number RMS-8301011. This updated EXP assembly is engineered for modern motorcycle engines and demanding riding conditions, delivering more direct power transfer, improved durability, and a smoother, more responsive lever feel. The redesigned system helps provide consistent clutch operation while supporting stronger power delivery across changing terrain and riding situations.
The EXP friction disk uses an updated base material designed to provide greater strength in high-temperature environments, helping it withstand the heat generated by high-performance clutch systems. Redesigned internal wall bases improve strength and rigidity, translating into a more connected feel at the lever. On the outer face of the EXP disk, friction pads use Rekluse’s proprietary friction design found on TorqDrive clutch plates. This design helps align oil-flow characteristics with the clutch pack beneath, promoting improved cooling and consistent engagement.
EXP 4.0 wedges now use rolling contact with built-in pins instead of sliding contact. By reducing friction and resistance during operation, the updated wedge design supports smoother engagement, faster response, and more controlled power delivery. Updated engagement curves are tailored to modern motorcycle engine characteristics, while multiple wedge weights and EXP spring options provide additional tuning flexibility for riders seeking a customized clutch response.
Designed for riders who demand dependable performance and precise control, the Rekluse RadiusX 4.0 Clutch combines advanced friction technology, improved thermal capability, and adjustable engagement characteristics in a purpose-built clutch upgrade for the Honda CRF450R. Follow the manufacturer’s application and installation requirements to ensure proper fitment and performance.
