Rekluse Racing RadiusCX 4.0 Auto Clutch Kit for Triumph TF450 Models – RMS-0412003

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-0412003 and vendor part number RMS-0412003, is designed for select Triumph TF450 motorcycles. This complete auto clutch system combines Rekluse TorqDrive friction disk technology, the EXP 4.0 disk, and Core technology to deliver smoother engagement, stronger power transfer, improved durability, and a more connected clutch lever feel.

The EXP 4.0 system uses an upgraded base material engineered for improved strength in high-temperature environments, along with a redesigned internal wall for increased rigidity. Its updated wedge design uses built-in pins and rolling contact instead of sliding contact, reducing friction and resistance for more responsive engagement and smoother power delivery. The outer friction pads use the proprietary TorqDrive friction design to support oil flow, cooling, and consistent clutch operation.

As an auto clutch system, the RadiusCX 4.0 helps prevent stalling and allows riders to start, stop, and navigate technical terrain without constantly operating the clutch lever. Riders can run a taller gear to help the suspension work more effectively while conserving energy. The clutch lever retains normal functionality, allowing full manual override of the auto-clutch operation whenever desired. The TorqDrive clutch pack is also designed to provide extended clutch life and require less adjustment over time.

This Rekluse Racing clutch kit fits 2025 Triumph TF450RC, 2025 Triumph TF450E, 2025 Triumph TF450X, 2026 Triumph TF450X, 2026 Triumph TF450RC, and 2026 Triumph TF450C models. Verify motorcycle model and year before installation.
