The REKLUSE RadiusCX 4.0 Clutch for Yamaha YZ125 (Part RMS-8907075) offers riders a significant upgrade in clutch performance, durability, and responsiveness. Built with advanced technology and innovative design features, this clutch assembly is engineered to enhance your riding experience, especially in demanding conditions where heat and consistent operation are critical. The updated EXP (expanding friction disk) assembly incorporates a new base material that provides better strength and heat resistance, ensuring reliable performance even in high-temperature environments. This feature is vital for maintaining clutch integrity during aggressive riding or extended use. The internal wall bases have been redesigned for increased strength and rigidity, translating into a more connected and confident lever feel for the rider. The external friction pads now feature a proprietary friction design similar to Rekluse TorqDrive clutch plates, which helps optimize oil flow beneath the clutch pack, promoting improved cooling and more consistent operation. Enhanced EXP 4.0 wedges utilize rolling contact with built-in pins, replacing traditional sliding contact. This innovation reduces friction and resistance, resulting in smoother engagement and a more responsive power delivery. The clutch's engagement curve has been carefully updated to better match modern motorcycle engine characteristics, providing a more direct and predictable power transfer. This makes the REKLUSE RadiusCX 4.0 not only more durable but also more rider-focused, offering a seamless riding experience across various terrains and riding styles.
