Rekluse Racing RadiusCX 4.0 Auto Clutch for Beta 125 RR and 200 RR, Part RMS-8902026

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 combines EXP 4.0, TorqDrive friction disk, and Core technology to deliver smoother engagement, stronger power transfer, and improved clutch durability. Designed for Beta two-stroke motorcycles, this complete auto clutch system 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, while the redesigned internal walls increase rigidity and help provide a more connected lever feel. Its updated wedge system uses built-in pins and rolling contact instead of sliding contact, reducing friction and resistance for smoother engagement, quicker response, and more consistent power delivery. Rekluse TorqDrive friction pad technology is integrated to support matching oil-flow characteristics within the clutch pack, promoting cooling performance and stable operation.

The RadiusCX 4.0 retains normal clutch-lever operation, allowing the rider to override the auto-clutch function whenever desired. It can help improve traction, rider control, and confidence while allowing use of a taller gear to reduce rider fatigue and let the suspension work more effectively. The TorqDrive clutch pack is designed to provide increased service life and require fewer adjustments over time.
