Product Overview
This high-quality Original Clutch Variator Plate Ramp is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2021-2024) models.
The clutch variator plate ramp sits behind the movable drive face and provides the angled contact surfaces that guide the roller weights as they move outward under centrifugal force. The ramp profile directly determines how the movable face responds at different engine speeds, controlling the rate and progression of belt ratio change through the CVT. A worn, warped, or damaged ramp plate causes irregular roller movement, leading to hesitant acceleration, belt slipping, and inconsistent power delivery. This original replacement restores the correct ramp geometry, ensuring accurate and responsive ratio changes throughout the rev range of your Honda PCX125.

Complete Part Guide
A worn or notched ramp plate prevents the variator from expanding correctly, leading to flat spots in power delivery and reduced top speed during North London commutes. Restoring the CVT efficiency on your Honda PCX125 2021-2024 requires the high-tolerance fit of this original Clutch Variator Plate Ramp (22131-K1Z-N20). Stored at Part Hive's London warehouse, complete your order before the 1 PM cutoff for guaranteed same-day UK dispatch.
We frequently find 2021-2024 Honda PCX-125 models where the transmission feels "sluggish" or exhibits a jerky take-off. Upon checking, we find that it's caused by burrs or uneven wear on the variator ramp plate. On the Honda PCX-125, the 22131-K1Z-N20 plate is a high-stress part, and once the surface becomes pitted from old roller weight dust, the rollers can no longer slide freely. This results in the engine "hunting" for the right RPM and places extra strain on the drive belt. This original Honda PCX-125 part ensures the sliding pieces move without friction, helping prevent the premature shredding of variator sliders and rollers common with low-grade aftermarket drivetrain parts.
