Rekluse RadiusX 4.0 Clutch Assembly for Suzuki RM-Z 450 (RMS-8306070)

Upgrade your Suzuki RM-Z 450 with the Rekluse RadiusX 4.0 Clutch Assembly, part number RMS-8306070. This updated EXP assembly is engineered to deliver more direct power transfer, smoother engagement, and improved durability for demanding off-road and motocross riding. Its revised construction is designed to withstand the elevated temperatures generated by high-performance clutch systems while providing a more connected lever feel and consistent operation.
The EXP disk features redesigned internal wall bases for increased strength and rigidity. Its external friction pads use Rekluse’s proprietary friction design found on TorqDrive clutch plates, helping match oil-flow characteristics within the clutch pack below. This promotes improved cooling capability and helps maintain predictable clutch performance during extended or high-heat operation. The result is rider-focused functionality with responsive control and dependable power delivery.
Rekluse EXP 4.0 wedges now use rolling contact with integrated pins instead of sliding contact. This design reduces friction and resistance within the assembly, supporting smoother engagement and a more responsive feel when applying power. Updated engagement-curve designs are optimized for modern motorcycle engine characteristics, helping the clutch deliver strong, controlled performance across a broad range of riding conditions.
