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 system is designed to enhance performance and rider control for select Suzuki models, including the RMZ450 and RMX450Z. Built with an upgraded base material, this clutch offers improved strength and durability, especially in high-temperature environments common during aggressive riding. The redesigned internal walls of the EXP 4.0 base provide increased rigidity, resulting in a more connected and responsive lever feel that translates into better control and confidence on the trail or track.
The external friction pads now feature a proprietary design matching Rekluse's TorqDrive clutch plates, which optimizes oil flow for improved cooling and consistent operation. The innovative wedge design utilizes rolling contact with built-in pins, vastly reducing friction—by up to 98%—which promotes smoother engagement and a more immediate power transfer. This enhancement ensures that the clutch responds seamlessly to rider input, providing a smoother, more predictable experience.
The RadiusCX 4.0 integrates advanced TorqDrive friction disk technology along with core innovations to deliver superior hook-up, durability, and lever feedback. This auto clutch system eliminates stalling, allowing for smoother starts and stops without clutch lever engagement, while still enabling full manual control when desired. Riders can run taller gears, improving suspension performance and saving energy over long rides. The system also extends clutch life and reduces the need for frequent adjustments, making it ideal for aggressive riding conditions.
With features tailored for modern engines, the RadiusCX 4.0 provides a direct power delivery, improved durability, and rider-focused functionality. Its upgraded design translates into more responsive engagement, better heat management, and overall enhanced performance. Whether navigating challenging terrain or seeking more precise control, the Rekluse RadiusCX 4.0 Clutch system offers a significant upgrade for Suzuki RMZ450 and RMX450Z riders seeking reliability and advanced technology.
