REKLUSE RadiusX 4.0 Clutch for XR650R RMS-8301019 – Enhanced High-Performance Expansion Friction Disk Assembly

The REKLUSE RadiusX 4.0 Clutch for XR650R (Part Number RMS-8301019) offers a significant upgrade in clutch performance through its innovative EXP (expanding friction disk) assembly. Featuring a redesigned base material, this clutch assembly provides improved strength and durability in high-temperature environments, which are common in demanding heat clutch systems. The internal wall bases have been reinforced for increased strength and rigidity, resulting in a more connected and precise lever feel for the rider, enhancing control and confidence during operation. Outside the EXP disk, the friction pads now incorporate a proprietary friction design akin to the Rekluse TorqDrive clutch plates, optimizing oil flow characteristics beneath the clutch pack. This modification promotes better cooling, which helps maintain consistent clutch performance under prolonged use or intense riding conditions. The EXP 4.0 wedges have been upgraded with rolling contact pins instead of sliding mechanisms. This change reduces friction and resistance during engagement, leading to smoother power delivery, improved responsiveness, and a more seamless connection between rider input and clutch engagement. Additionally, these improvements translate into more direct power transfer, enhanced durability, and a rider-focused feel. The updated engagement curve is tailored to match modern motorcycle engine characteristics, providing smoother engagement across a range of RPMs. The clutch system offers increased tuning flexibility with a variety of wedge weights and EXP springs, allowing riders to customize the clutch feel and performance to suit their riding style. Overall, the REKLUSE RadiusX 4.0 Clutch is designed to deliver stronger power transfer, better cooling, and increased reliability, making it an ideal upgrade for serious off-road riders seeking consistent, high-performance clutch operation in their XR650R.
