Rekluse Racing RadiusCX 4.0 Auto Clutch Kit, RMS-8912003, Triumph TF450

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, manufacturer part number RMS-8912003 and vendor part number RMS-8912003, combines Rekluse TorqDrive friction disk technology, EXP 4.0 automatic clutch technology, and Core components for improved engagement, power transfer, lever feel, and durability. Designed for riders seeking consistent clutch performance in demanding conditions, this kit helps reduce stalling while maintaining full manual control through the clutch lever.

The EXP 4.0 clutch base uses an upgraded material engineered for improved strength in high-temperature environments. Its redesigned internal wall increases rigidity and contributes to a more connected lever feel. The updated friction pads use Rekluse’s proprietary TorqDrive friction design, helping align oil-flow characteristics with the surrounding clutch pack to support cooling and consistent operation. Built-in pins allow the revised wedges to use rolling contact instead of sliding contact, reducing friction and resistance for smoother engagement, quicker response, and stronger power delivery.

The RadiusCX 4.0 is engineered to fit select Triumph TF450 models, including the 2025 Triumph TF450E, 2025 Triumph TF450X, 2026 Triumph TF450X, and 2026 Triumph TF450C. It helps riders start and stop without constantly operating the clutch lever, run a taller gear when appropriate, improve traction and control, and navigate technical terrain with greater confidence. The TorqDrive clutch pack is designed to provide extended clutch life and reduced adjustment requirements over time while retaining the ability to fully override the automatic function with normal lever operation.
