Rekluse RadiusCX 4.0 Clutch for Honda CRF450R (RMS-8901010)

Upgrade your Honda CRF450R clutch system with the Rekluse RadiusCX 4.0 Clutch, Part RMS-8901010. Designed for demanding motocross and off-road riding, this updated EXP assembly delivers smoother engagement, more direct power transfer, and improved durability. The revised friction disk uses an enhanced base material engineered for greater strength in high-temperature environments created by modern high-performance clutch systems.

Rekluse redesigned the internal wall bases of the EXP assembly to increase strength and rigidity, helping provide a more connected lever feel and consistent rider feedback. The outer EXP disk now incorporates friction pads based on the proprietary friction design used in Rekluse TorqDrive clutch plates. This design helps complement oil flow characteristics within the clutch pack, promoting improved cooling and dependable operation during demanding rides.

The EXP 4.0 wedges feature rolling contact with integrated pins instead of traditional sliding contact. Reduced friction and resistance help create smoother clutch engagement, quicker response, and stronger overall power delivery. Updated engagement curve designs are tailored to modern motorcycle engine characteristics, while multiple wedge weight and EXP spring options provide additional tuning flexibility for riders seeking a personalized feel and performance balance.

Built for riders who demand precise control and reliable performance, the Rekluse RadiusCX 4.0 Clutch combines durable construction with rider-focused functionality. Confirm vehicle compatibility before installation and follow Rekluse installation and tuning instructions for the best results.
