3. Installation and Setup

Installation of the Rekluse RadiusCX Auto Clutch requires mechanical proficiency. It is recommended that installation be performed by a qualified technician. Refer to the detailed installation guide provided with your product for specific steps and torque specifications. General steps include:

4. Operating Instructions

The Rekluse RadiusCX Auto Clutch provides automatic clutch engagement and disengagement, allowing the rider to focus on throttle, braking, and steering. While the clutch operates automatically, the clutch lever remains functional for manual override and fine control.

• Starting the Engine: The engine can be started in any gear without pulling the clutch lever, as the auto clutch will be disengaged at idle RPM.
• Riding: As engine RPM increases, the auto clutch engages smoothly, transferring power to the rear wheel. The clutch will disengage automatically when RPM drops, preventing stalls.
• Manual Clutch Lever Use: The clutch lever can still be used for aggressive starts, shifting, or to override the auto function for specific riding techniques. The optimized pressure plate design ensures a consistent lever feel.
• Stopping: The auto clutch will disengage as the motorcycle comes to a stop, allowing the engine to remain running without needing to pull the clutch lever or shift to neutral.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Rekluse RadiusCX Auto Clutch. Adhere to the following guidelines:

• Oil Changes: Follow your motorcycle manufacturer's recommendations for oil change intervals. Use high-quality motorcycle-specific engine oil. The Core components are designed for improved oil flow.
• Clutch Adjustment: Periodically check and adjust clutch lever free play according to the Rekluse manual. While TorqDrive friction disks provide longer clutch life with less adjustment, occasional checks are still necessary.
• Component Inspection: During routine maintenance, inspect clutch components for wear, particularly the friction disks, steel plates, and EXP disk. Replace any worn components as necessary.
• Basket Sleeves: The Rekluse basket sleeves are designed to prevent wear, but it is good practice to inspect the clutch basket for any signs of notching during major services.
