The Rekluse RadiusX 4.0 Clutch is an updated expanding friction disk assembly designed for Husaberg and KTM applications. Manufacturer part number RMS-8313038, this clutch assembly features a strengthened base material developed to perform in the high-temperature environments created by clutch systems.
Redesigned internal wall bases provide increased strength and rigidity to help deliver a more connected lever feel for the rider. The outside of the EXP disk uses friction pads based on Rekluse's proprietary TorqDrive clutch plate design, matching oil flow characteristics in the clutch pack beneath to promote improved cooling capability and consistent operation.
EXP 4.0 wedges use rolling contact with built-in pins. Compared with sliding contact, the rolling-pin design reduces friction and resistance for smoother engagement and a more responsive feel. The updated engagement curve is designed to better match modern motorcycle engine characteristics, supporting more direct power delivery, improved durability and rider-focused functionality. The system also offers tuning options through varying wedge weights and EXP springs.
