Rekluse clutch system RadiusX 4.0 (DDS)

• Rekluse EXP 4.0 Auto Technology Benefits
• Referring to Rekluse's 'auto clutch' systems is much more simply stated than achieved. Auto clutch technology has been meticulously engineered, tested and developed through several generations in the engines of many different brands and types of motorcycles. But what are the benefits of running an auto clutch in the first place?
• Benefits of an Auto Clutch and How it Works. Swing a leg over a motorcycle equipped with a Rekluse auto clutch system – whether it be a RadiusX or RadiusCX – roll on the throttle and you'll notice you can start and stop without the clutch lever. The automatic engagement and disengagement of the clutch is based on engine RPM, allowing the EXP disk to do on its own what you'd normally do by pulling in the lever. This eliminates stalling and improves rider control, maximising traction and confidence to navigate challenging terrain. Plus, riders can run a gear taller, allowing the suspension and chassis to settle and work better.
• The EXP disc is the magic ingredient behind the functionality and benefits of Rekluse auto clutches. About 10 years ago, Rekluse introduced an innovatively redesigned version of its revolutionary auto clutch technology with EXP 3.0. The years of racing, testing and development since have led to Rekluse's most refined auto clutch experience yet: EXP 4.0. Rekluse engineers went through every aspect of the EXP auto clutch disc design to achieve three major goals: more direct power delivery, improved durability and rider-focused functionality.
• How can you upgrade your Rekluse 3.0 auto clutch to 4.0? If your bike is already equipped with a Rekluse auto clutch system using EXP 3.0 – whether RadiusX, RadiusCX or Core EXP 3.0 – there's a quick and convenient option for you. Depending on your system, you can choose an EXP 4.0 assembly on its own, or an EXP 4.0 assembly plus a fresh clutch pack complete with drive plates, TorqDrive friction disks and basket sleeves (for applicable models).
• The upgrade is simple! Backwards compatibility with Rekluse 3.0 systems is drop-in ready: simply replace your EXP 3.0 disc with your new EXP 4.0 disc and you're ready to enjoy all the advantages of the latest-generation auto clutch.
• What changed from EXP 3.0 to EXP 4.0? First, the base material used for EXP 4.0 has been updated to provide better strength at high temperatures, critical given the heat clutch systems create. Next, the internal wall of the EXP 4.0 bases was redesigned for strength and rigidity, which translates into 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 of Rekluse TorqDrive clutch plates. This friction pad design matches the oil flow characteristics of the clutch pack beneath, promoting improved cooling and consistent operation.
• The 'wedges' are a critical component of 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 use rolling contact with built-in pins. Rolling instead of sliding creates less friction and resistance, providing smoother engagement and a more responsive feel, and stronger power delivery overall.
• More direct power delivery, improved durability and rider-focused functionality
• Upgraded base material providing improved strength at high temperatures
• Revised base design improving strength and rigidity, translating to a more connected lever feel
• Improved wedge design with pins allows rolling instead of sliding to expand the disk, creating a more responsive feel and smoother engagement
• TorqDrive friction pad design matches revised oil flow characteristics
• Engagement curve designs updated to better match modern motorcycle engine characteristics
• More tuning options with varying wedge weights and EXP springs
