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.\n\u003cp\u003eThe Rekluse RadiusCX 4.0 auto clutch combines EXP 4.0, TorqDrive friction disk, and Core technology to deliver smoother engagement, stronger power transfer, and improved rider control. Designed for demanding off-road use, this clutch system helps reduce stalling and allows riders to start, stop, and navigate technical terrain with less need to operate the clutch lever.\u003c\/p\u003e\u003cp\u003eThe EXP 4.0 base uses an upgraded material for improved strength in high-temperature environments, while the redesigned internal wall increases rigidity and contributes to 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, faster response, and more consistent power delivery. Rekluse friction pad technology also helps optimize oil flow through the clutch pack, supporting cooling performance and reliable operation.\u003c\/p\u003e\u003cp\u003eThe TorqDrive clutch pack provides increased power transfer compared with the original equipment clutch and is engineered for extended clutch life with less adjustment over time. Riders retain full use of the clutch lever and can override the automatic clutch function whenever needed. The RadiusCX 4.0 is an advanced auto clutch solution for riders seeking improved traction, confidence, and control in challenging conditions.\u003c\/p\u003e\u003cp\u003eManufacturer: Rekluse Racing.
