Rekluse RadiusCX 4.0 Clutch for Honda CR250R/CR500R (RMS-8901021)

Upgrade clutch performance on compatible Honda CR250R and CR500R motorcycles with the Rekluse RadiusCX 4.0 Clutch, Part RMS-8901021. This updated EXP assembly is engineered to deliver more direct power transfer, improved durability, and a smoother, more responsive feel for riders who demand consistent performance in challenging conditions. Its refined design helps the clutch respond more effectively to modern engine characteristics while providing additional tuning flexibility through selectable wedge weights and EXP springs.
The EXP assembly uses an updated base material designed for improved strength in the high-temperature environment created by clutch operation. Redesigned internal wall bases add strength and rigidity, helping translate clutch engagement into a more connected lever feel. On the outer face of the EXP disk, friction pads use Rekluse’s proprietary friction design found in TorqDrive clutch plates. The matched design helps support compatible oil-flow characteristics through the clutch pack, promoting improved cooling capability and consistent operation.
The RadiusCX 4.0 EXP wedges now feature rolling contact with integrated pins. Compared with sliding contact, rolling pins reduce friction and resistance during engagement, helping create smoother operation, quicker response, and stronger overall power delivery. These updates are intended to improve clutch feel and functional durability while maintaining rider-focused control across changing riding conditions. The engagement curve is also revised to better complement current motorcycle engine characteristics, giving riders more options to tailor clutch behavior to their preferred performance requirements.
Designed for riders seeking a refined automatic-assist clutch experience, the Rekluse RadiusCX 4.0 combines updated materials, optimized friction technology, and improved wedge operation in one performance-focused assembly. Verify motorcycle compatibility before installation and follow Rekluse installation and adjustment procedures for the best results.
