Motorcycle visor fitment dataset: verified shared-shield groups and helmet model index

Replacement visors are sold by helmet model, but helmets are not sold under one name. The same shell is often marketed under a different model name in the UK and in the United States, and several different helmets from one manufacturer frequently take a single shield. Anyone trying to work out which visor fits their helmet has to reconstruct that mapping from scattered retailer listings.

This page publishes the mapping in one place, in two tables: the helmet groups that are verified to share one replacement shield, and an index of every helmet model the ClearLine catalogue covers with the aftermarket visor types listed for it. Both tables are generated from named data files, and every figure below is counted from those files rather than stated from memory.

Scope: Great Britain. Compiled 2026-08-10.

What the dataset contains

• 15 verified shared-shield groups, covering 43 helmet model names between them. 15 of those groups record both a UK and European name and a United States name for the helmets in the group.
• 429 helmet models across 27 brands, derived from 620 product listings.
• Which aftermarket visor types are listed for each model: replacement visors (304 listings), photochromic visors (160) and anti-fog inserts (156).
• 13 shield part codes, separated out from helmet model names so that a search for a part code does not return a helmet.

Method

Helmet model names were extracted from the fitment list attached to each of the 620 product listings and classified against a brand index. A token that begins with a known brand name is treated as a helmet model. A token that matches a known shield part code is treated as a part, not a helmet. Anything that is neither is left unclassified and excluded rather than guessed; 1 token was excluded on that basis when this page was compiled.

The shared-shield groups come from a separate map in which each group was researched against manufacturer parts documentation and independent retailer fitment lists, and then subjected to a deliberate attempt to refute it. Only groups that survived that attempt are marked verified, and only verified groups appear in the first table below. Each group carries the manufacturer’s own shield code and a confidence rating recorded during that research.

What the dataset deliberately does not claim

The obvious way to build a fitment table is to say that any two helmets named in the same product listing must take the same visor. That method is wrong, and our own data measures how wrong.

• 316 listings excluded from co-fitment. Anti-fog and photochromic listings say nothing about visor interchangeability, because an insert fits over or replaces a visor across many unrelated helmets. A single anti-fog listing in this catalogue spans eight brands.
• 18 listings contradict the verified data outright. These are replacement-visor listings whose own model list spans two groups that the verified map records as taking different shields. Deriving co-fitment from listings would therefore publish fitment claims that our better data refutes, so it is not done here.
• 9 listings name models from more than one brand. These are unverified supplier compatibility claims and are never presented as shared fitment.
• No “also fits” column. The second table is a coverage index, not a fitment index. The only cross-model fitment stated anywhere on this page is the verified-group column, which comes from the shared-shield map and from nothing else. Of the 429 models indexed, 43 currently sit in a verified group; the rest are marked not verified, which means research has not been completed, not that they are incompatible.

The verified groups published today cover two manufacturers. That is a limit of the research completed so far rather than a statement about the other brands in the index, and the table will be extended as further groups are verified.

Table 1: verified shared-shield groups

Read the grouping criterion carefully, because it is narrower than it looks. A group here means one thing only: the models listed take the same replacement shield. It does not mean the helmets are the same helmet. Two patterns are mixed together in the table and the research notes distinguish them. In some groups the names genuinely are one helmet sold in different markets. In others — the Shoei RYD and RF-SR, the Arai Signet-X and QV-Pro, the Arai Regent-X and Profile-V, the Arai Quantic and Contour-X — the members are documented as distinct helmets, with different shells or different market tiers, that happen to share one shield. The “also sold as” column should be read as the regional names recorded for a group, not as proof that every member is the same helmet, and nothing here should be taken to mean that two helmets in one group have the same fit, shape or sizing.

Fitment is not legality

Whether a visor fits a helmet and whether it may be used on the road are two different questions, and nothing in the tables above answers the second one. Neither table records approval markings, and no row should be read as saying that a visor is permitted for road use. The wording ClearLine uses on its product pages is reproduced here in full so that this page states the position no more strongly than the catalogue does:

Whether a visor may be used on the road depends on the approval marking it carries — a BS 4110 grade with an approved certification mark, or an ECE 22.05 approval — not on its tint. We cannot confirm the marking on an individual item, so we do not offer these as authorised for road use; check the marking on the visor you receive and your local law. Mirrored, iridium and dark-smoke finishes transmit too little light to be legal for road use in the UK and are intended for off-road, track and closed-course daytime use.

This page is scoped to Great Britain and is general information, not legal advice.

Names and affiliation

Helmet model names and shield part codes are the marks of their respective manufacturers. They appear here only to identify which helmet a visor fits, which is the ordinary and necessary way to describe aftermarket fitment. ClearLine is an independent aftermarket seller and is not affiliated with, endorsed by or authorised by any helmet manufacturer named on this page.

Corrections are welcome. If a group here is wrong, or a helmet you can document as sharing a shield is missing, the correction will be researched and the table updated with the source recorded.
