Spare Part - HJC RPHA 71 Base Plate - HJ-40

The HJC HJ-40 Gear (Base) Plate Set is the genuine replacement visor mechanism plate set for the HJC RPHA 71 helmet. The base plates are what the visor pivots on, so they take constant use every time you open, close or crack the shield — over time they can wear, become stiff or get damaged in a drop.

This is a straightforward spare part for RPHA 71 owners who want to restore the original visor action rather than replace an otherwise good helmet. Fitting genuine HJC components keeps the visor working with the shell and seal as the manufacturer intended.

Please confirm your helmet model before ordering — this set is listed for the RPHA 71.

Check your helmet model before fitting — this set is listed for the RPHA 71 and may not suit other HJC shells.
Fit in line with the instructions supplied with your helmet; make sure the plate seats fully and any fasteners are firm without over-tightening into the plastic.
After fitting, cycle the visor through its full range and confirm it holds each position and closes flush against the seal before you ride.
Keep the plate and visor track free of grit, dust and road grime — build-up is the usual cause of stiff or noisy visor movement.
Clean with a soft cloth and mild soapy water only; avoid petrol, solvents and strong household cleaners, which can weaken helmet plastics.
Avoid oil-based lubricants on the mechanism; if movement feels tight, clean it rather than forcing the visor.
Replace the plates if they are cracked, distorted, or the visor no longer holds position — do not ride with a loose or partially secured visor.
Store spare plates in their packaging, out of direct sunlight and away from heat sources.
