Rekluse Racing RadiusCX 4.0 Auto Clutch Kit for KTM and Husqvarna 125 Models, RMS-8913291

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 Auto Clutch Kit combines EXP 4.0, TorqDrive friction disk, and Core technologies to deliver smoother engagement, stronger power transfer, and improved rider control. Manufacturer part number RMS-8913291, also identified by vendor part number RMS-8913291, this clutch system is designed for select KTM and Husqvarna 125 motorcycles. It helps reduce stalling and allows riders to start, stop, and navigate technical terrain with less need to operate the clutch lever.

The EXP 4.0 base uses an upgraded material for improved strength in high-temperature environments created by modern clutch systems. Its revised internal wall design increases rigidity and supports a more connected lever feel. The updated wedge system uses built-in pins for rolling contact rather than sliding contact, reducing friction and resistance by up to 98 percent for smoother engagement, more responsive operation, and stronger power delivery.

TorqDrive friction pad technology matches the proprietary design used in Rekluse TorqDrive clutch plates. This design supports compatible oil flow characteristics within the clutch pack, promoting improved cooling and consistent performance. The clutch retains normal manual lever operation, allowing the rider to override the auto-clutch function whenever desired. It can also help riders run a taller gear, improve traction, and reduce fatigue while maintaining better control over challenging terrain.

The Rekluse Racing RadiusCX 4.0 RMS-8913291 fits 2023, 2024, and 2025 KTM 125 SX models, 2026 KTM 125 SX, and 2023 through 2026 Husqvarna TC 125 models. Verify motorcycle year and model compatibility before installation.
