REKLUSE RADIUS X 4.

Updated EXP (Expanding Friction Disk) Kit
Updated base material to provide better resistance in high-temperature environments, essential for creating thermal clutch systems.
Redesigned internal wall bases for increased strength and rigidity, resulting in a more connected lever feel for the rider.
On the outside of the EXP disk, the friction pads now match the exclusive friction design found on Rekluse TorqDrive clutch disks. This design helps adapt oil flow characteristics to the clutch pack below, promoting improved cooling capacity and consistent operation.
EXP 4.0 wedges have been enhanced to now use rolling contact with integrated pins.
Rolling contact versus slipping creates less friction and resistance, offering smoother engagement and a more responsive feel, creating overall stronger power delivery.
More direct power delivery, improved durability, and rider-focused functionality.
Updated engagement curve designs to better match the characteristics of modern motorcycle engines.
More tuning options with different wedge weights and EXP springs.
