The Rekluse RadiusX 4.0 Clutch is an updated expanding friction disk assembly designed for clutch systems that generate significant heat. Its revised base material provides improved strength in high-temperature environments, while redesigned internal wall bases increase strength and rigidity for a more connected lever feel.
The outer EXP disk uses friction pads based on Rekluse’s proprietary TorqDrive clutch plate design. This construction is intended to match oil-flow characteristics within the clutch pack, 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 are intended to better match modern motorcycle engine characteristics. The assembly also provides tuning options through varying wedge weights and EXP springs. Distributor part number: RMS-8308001. Manufacturer part number: RMS-8308001. Vehicle fitment includes the 2018 Sherco 250 SE-SD Six Days, 2019 Sherco 250 SC, 2018 Sherco 300 SE-SD Six Days, 2019 Sherco 300 SE-R Racing, 2018 Sherco 300 SE-R, 2019 Sherco 300 SCF, 2018 Sherco 250 SE-R, 2019 Sherco 250 SE-R Racing and 2019 Sherco 300 SE Factory.
