The HJC RPHA ST collection now consists of replacement parts for the discontinued helmet platform rather than complete helmets. Current products include HJ-20ST outer visors, a matching gear-plate set, the HJ-L1 internal sun visor and a size-specific comfort liner. Part numbers matter because several HJC shields have similar names but different mounting geometry.
Choose clear for the broadest range of light conditions or dark smoke for suitable daylight use, subject to current UK road-use requirements. HJC's compatibility table lists HJ-20ST for the RPHA ST; it is different from HJ-20, HJ-20M and HJ-20P.
The gear plates form part of the outer visor mechanism and are listed for the RPHA ST and FG-ST. HJ-L1 is the separate internal sun visor that HJC lists for the RPHA ST and RPHA 70.
Interior padding must match the original helmet size and attachment layout. Check the label inside the helmet, not merely the apparent thickness of the old liner, which may have compressed over time.
A replacement liner or visor can restore a serviceable component, but it does not renew an aged or impact-damaged shell. Inspect the helmet and follow HJC's care and replacement guidance.
The collection separates outer visors, mechanism parts, internal shielding and comfort padding with model codes in the product titles. That makes it easier to replace the correct component without treating every RPHA part as interchangeable. Browse helmet spares and accessories if you need another HJC model or part type.

No. Match the liner to the helmet model and labelled size.
