The REKLUSE RadiusX 4.0 Clutch is an updated expanding friction disk assembly designed for select KTM motorcycles. Its base material is updated for improved strength in high-temperature clutch environments, while redesigned internal wall bases improve strength and rigidity for a more connected lever feel.
The outside of the EXP disk uses friction pads matching the proprietary friction design found on REKLUSE TorqDrive clutch plates. This design matches oil-flow characteristics in the clutch pack beneath, promoting improved cooling capability and consistent operation. EXP 4.0 wedges now use rolling contact with built-in pins, reducing friction and resistance compared with sliding contact for smoother engagement, a more responsive feel and stronger power delivery.
Updated engagement curve designs better match modern motorcycle engine characteristics. The system also provides more tuning options through varying wedge weights and EXP springs. Distributor part number: RMS-8313032. Manufacturer part number: RMS-8313032. Vehicle fitment includes the 2010 KTM 450 XC-W, 2009 KTM 530 EXC Six Days, 2011 KTM 450 EXC, 2010 KTM 450 EXC Champions Edition, 2010 KTM 450 XC-W Six Days, 2009 KTM 400 EXC Racing 4-Stroke, 2008 KTM 450 EXC-R, 2009 KTM 450 XC-W, 2011 KTM 450 XC-W and 2011 KTM 400 EXC Racing 4-Stroke.
