RadiusCX 4.0 (DDS)
Overview
RadiusCX is the complete package of auto clutch functionality, improved power delivery, and upgraded durability. RadiusCX kits include Rekluse’s next-generation EXP 4.0 auto clutch disk, billet aluminum inner hub and pressure plate Core components, TorqDrive friction disk technology, plus a clutch cover top it off. TorqDrive disks and EXP 4.0 provide stronger power delivery and a more reliable, responsive clutch modulation. Rekluse’s billet Core components help keep the clutch cooler and resist wear with improved oil flow and hard anodized coatings, plus provide an improved, consistent lever feel.
What Changes were made with EXP 4.0 from EXP 3.0?
First, 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 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 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.
Not only is engagement smoother and more responsive, but the engagement curves of EXP 4.0 have been designed to better match the engine characteristics of modern motorcycles. Improved tuning options play a role in this as well, as riders now have the option to set up their EXP 4.0 with a combination of light, medium and heavy wedge weights in addition to having multiple EXP disk spring options as they did with 3.0. This creates much more potential for riders to optimize their clutch and engine characteristics based on riding conditions. However, if you’re a rider that likes load-up and go, EXP 4.0 comes with recommended settings out of the box.
