Description
If you’re running a Yamaha and demand clutch engagement that matches your riding precision, the REKLUSE RadiusX 4.0 delivers the direct power transfer and thermal durability that separates competitive performance from the rest. The redesigned EXP assembly eliminates parasitic friction losses while maintaining consistent operation even under sustained high-heat conditions—critical when every millisecond of throttle response matters. You get a smoother, more responsive engagement curve that works with modern engine characteristics, not against them.
