Rekluse Racing RadiusCX 4.0 Clutch for Husqvarna/KTM, Part Number RMS-8913080, SKU 156-18263

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 combines TorqDrive friction disk technology, EXP 4.0 technology and Core technology in an auto clutch system designed to provide strong power delivery, responsive engagement and consistent operation. The updated EXP 4.0 base material improves strength in high-temperature environments, while the redesigned internal wall enhances strength and rigidity for a more connected lever feel.

The EXP 4.0 wedge system uses built-in pins for rolling contact instead of sliding contact. This design reduces friction and resistance, supporting smoother engagement, a more responsive feel and stronger power delivery. The friction pads on the outside of the EXP disk use the proprietary friction design found on Rekluse TorqDrive clutch plates, matching the oil flow characteristics of the clutch pack to promote improved cooling capability and consistent operation.

Auto clutch functionality helps reduce stalling and allows start-and-stop riding without engaging the clutch lever. The system is designed to increase power transfer over OEM equipment, help riders run a taller gear and improve control, traction and confidence in challenging terrain. Riders retain normal use of the clutch lever and can override the auto functionality at any time. This Rekluse Racing clutch is identified by SKU 156-18263 and part number RMS-8913080.
