The REKLUSE Radiusx 4.0 Clutch is an updated expanding friction disk assembly designed for compatible Beta motorcycle clutch systems. Its base material is updated for improved strength in high-temperature environments, while redesigned internal wall bases provide greater strength and rigidity to help deliver a more connected lever feel for the rider.
The outside of the EXP disk uses friction pads that match 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 use rolling contact with built-in pins, reducing friction and resistance compared with sliding contact for smoother engagement, a more responsive feel and more direct power delivery.
Updated engagement curve designs are intended to better match modern motorcycle engine characteristics. The clutch also provides more tuning options through varying wedge weights and EXP springs. The REKLUSE Radiusx 4.0 Clutch has distributor part number RMS-8302023 and fits the 2011, 2012, 2013 and 2014 Beta 400 RR; 2011, 2012, 2013 and 2014 Beta 450 RR; 2016 Beta 390 RR; 2016 Beta 430 RR-Race Edition; 2014 Beta 400 RS; and 2015 Beta 430 RR.
