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 (Part Number: RMS-8913080) is engineered to enhance performance and rider control for select Husqvarna and KTM models from 2017 to 2019. Featuring advanced EXP 4.0 technology, this clutch offers a significant upgrade in durability, responsiveness, and high-temperature strength. The updated base material ensures better resilience under demanding riding conditions, while the redesigned internal wall improves rigidity and connection feel, translating to more precise control during aggressive riding. The friction pads on the outside are now matched with proprietary design elements found on Rekluse TorqDrive clutch plates, which helps optimize oil flow, improve cooling, and maintain consistent operation for extended periods of use. The innovative wedge system has been upgraded from sliding Teflon components to rolling contact pins, reducing friction by 98% and delivering smoother, more responsive engagement and stronger power transfer. The result is an auto clutch that not only simplifies start-stop maneuvering but also enhances overall performance, allowing riders to run taller gears, reduce fatigue, and navigate challenging terrain with greater confidence. The integrated TorqDrive friction disk technology further improves clutch longevity and minimizes adjustment needs, ensuring reliable operation over time. The EXP 4.0’s refined engagement curve and improved durability make it ideal for riders seeking maximum control and efficiency in demanding off-road environments. Whether you are racing or trail riding, the RadiusCX 4.0 Clutch provides a seamless combination of modern technology and rugged performance, elevating your motorcycle's capabilities and rider experience.
