The base material used for EXP 4.0 has been updated to provide better strength in high temperature environments, critical for the heat clutch systems create. Next, the internal wall of the EXP 4.0 bases were redesigned for strength and rigidity, which helps translate to a more connected lever feel for the rider. On the outside of the EXP disk, riders will notice the friction pads now match the proprietary friction design found on Rekluse TorqDrive clutch plates. Applying this friction pad design helps match oil flow characteristics of the clutch pack beneath, promoting improved cooling capability and consistent operation. The ‘wedges’ are a critical component to the centrifugal functionality of EXP 4.0. In the previous iteration, the Teflon wedges would slide up and down ramps built into the EXP bases to engage and disengage the clutch. EXP 4.0’s wedge has been improved to now use rolling contact with built-in pins. Rolling versus sliding creates less friction and resistance, providing smoother engagement and a more responsive feel, creating stronger power delivery overall. New roller design reduces the friction coefficient by 98% When you need the best, look no further than RadiusCX it is the top of the line auto clutch product that brings together all of our latest technology into one package. TorqDrive friction disk technology coupled with the new EXP 4.0 and our Core technology results in significant advancement in auto performance with exceptional hook-up, lever feel and durability. Just when you thought auto couldn’t get better, RadiusCX 4.0 has raised the bar.
The REKLUSE RACING RadiusCX 4.0 Clutch Hon (Part Number: RMS-8901001) is designed to deliver exceptional performance and reliability for Honda CRF250R and CRF250RX models from 2018 to 2021. This advanced auto clutch system incorporates the latest technological improvements to enhance power transfer, rider control, and durability in demanding off-road and motocross environments. Constructed with upgraded base materials that provide better strength at high temperatures, the RadiusCX 4.0 ensures consistent operation under rigorous conditions. The redesigned internal wall of the clutch base increases rigidity, resulting in a more connected lever feel, which translates into improved rider confidence and control. The external friction pads match the proprietary friction design found on Rekluse TorqDrive clutch plates, optimizing oil flow and cooling, thereby promoting longer clutch life and more stable engagement. The critical wedge component has been upgraded to a rolling contact design with built-in pins, reducing friction by 98% compared to the previous sliding design. This innovation offers smoother clutch engagement, more responsive power delivery, and a better overall riding experience. The system's engagement curve has been refined to better match modern engine characteristics, providing a more direct and predictable power transfer. The RadiusCX 4.0 not only eliminates stalling during starts and stops but also allows riders to run taller gears for improved suspension performance and energy efficiency. The clutch retains full manual control, enabling riders to override the auto functionality whenever desired, making it versatile for various riding conditions. Overall, the RadiusCX 4.0 combines TorqDrive friction disk technology with advanced design features to maximize durability, traction, and rider confidence across challenging terrains. Whether for competitive racing or recreational riding, this clutch system offers a significant upgrade over OEM components, ensuring optimal performance and longevity.
