Buying a replacement shield for an AGV is not really a question about your helmet’s name. It is a question about which fitment group your helmet belongs to. AGV has reused the same shield across several models for years, which is why the visors that fit AGV helmets are best understood as seven shared-shield groups rather than as twenty separate part numbers.
Get the group right and you have a wide choice of tints, an auto-tinting option and an anti-fog insert. Get it wrong and you have a shield that looks almost correct, seats badly, and whistles at motorway speed. This guide ranks the seven groups by how much they actually cover.
The short answer
- The broadest group is the K1 family — one shield covers the K1, K1 S, K3 SV, K5 and K5 S, and all three shield types are stocked for it.
- The race group is next — Corsa R, Corsa RR, Pista GP R, Pista GP RR and Race 3 share a shield.
- The generation trap is the K3. The New K3 introduced in 2023 does not take the older K3 shield, and this is the single most common ordering mistake on the marque.
- Ranking criterion: how many AGV models one shield part covers, then how many of the three shield types — replacement visor, photochromic visor, anti-fog insert — are stocked for that group.
- Nothing here is ranked on price, ratings or popularity. Those are either not comparable across groups or not something we hold honest data on.
How we ranked the visors that fit AGV helmets
Every row below was taken from the live product listings on this site, checked on the day of writing. The primary measure is fitment breadth: how many distinct AGV models a single shield part is listed as covering. That measure is useful to a buyer because a broad group means more tint choice, easier replacement later, and a better chance the same shield carries over to your next helmet.
The second measure is depth. Each group is scored on how many of the three shield types exist for it.
A replacement visor is the shield itself in a fixed tint. A photochromic visor darkens in daylight and clears again in low light. An anti-fog insert is a second inner lens that fits inside a prepared shield to stop condensation forming.
Where two groups cover the same number of models, the group with more separate listings on the site ranks higher, because that is a direct measure of how much tint and format choice you actually have. You can check any of this yourself from the category of visors that fit AGV helmets, and if your model is not named below, the visor finder tool will match it.
Two things are deliberately absent from the table. There is no price column, because listings here are variable products with a range rather than one number, and the store presents several currencies. There is no road-legal column either, for a reason set out in full further down: legality is decided by the marking on the individual shield, not by a category it sits in.
The seven AGV fitment groups compared
| Rank | Fitment group | AGV models covered | Models | Replacement visor | Photochromic | Anti-fog insert |
|---|---|---|---|---|---|---|
| 1 | K1 family | K1, K1 S, K3 SV, K5, K5 S | 5 | Yes | Yes | Yes |
| 2 | Corsa R race group | Corsa R, Corsa RR, Pista GP R, Pista GP RR, Race 3 | 5 | Yes | Yes | Yes |
| 3 | Compact ST touring group | Compact ST, GT4, K1, K1 S, K3 SV | 5 | Yes | Yes | Yes |
| 4 | Pista and Race group | Pista GP R, Pista GP RR, Race 2, Race 3 | 4 | Shared with group 2 | Yes | Yes |
| 5 | New K3 group | New K3 (2023 on), K3, K4 | 3 | Yes | Yes | Yes |
| 6 | K6 group | K6, K6 S | 2 | Yes | Yes | Yes |
| 7 | K5 Jet and K5 Plus | K5 Jet, K5 Plus | 2 | Yes | No | Universal only |
Read the table by row, not by column. A high rank means the group is well served, not that the helmet is better. A K6 owner is not worse off than a K1 owner just because the K6 shield covers fewer models — it simply means the part is more specific to that helmet.
1. The K1 family: K1, K1 S, K3 SV, K5 and K5 S
This is the broadest fitment group on the marque and the one with the most choice behind it. A single shield is listed as fitting the K1, K1 S, K3 SV, K5 S and K5, which covers the two highest-demand AGV families we see. If you own any of these five, you are in the best-supplied position of any AGV rider.
The replacement visor for the K1, K3 SV and K5 carries the widest tint spread in the group. The stocked options run from clear through a light smoke to a set of mirrored finishes: silver, gold, ice blue, deep blue, deep red, deep purple, rose red and a rainbow. That is the full range in one listing, which is why this group ranks first on depth as well as breadth.
Photochromic is available for the same group as a separate listing, and so is an anti-fog insert. The insert versions are worth a second look because several of them are cross-brand parts — the same insert is listed as fitting an Arai RX-7X, an HJC RPHA-11 or a Shoei NXR alongside the AGV models. If you keep a second helmet in the garage, one insert may serve both.
The thing to check before ordering is the K5 versus K5 S versus K5 Jet distinction. The K5 and K5 S sit inside this group. The K5 Jet is an open-face helmet and does not, which is covered in group seven. The name similarity is doing a lot of damage here, so read the shell rather than the badge.
2. The Corsa R race group: Corsa R, Corsa RR, Pista GP R, Pista GP RR and Race 3
The race group is the second-broadest and, for a track-focused rider, the most useful to understand. One shield is listed across the Corsa R, Corsa RR, Pista GP R and Pista GP RR, with several listings extending the same part to the Race 3. These are AGV’s competition shells and they have shared shield geometry across generations more consistently than the road range.
The replacement visor for the Corsa R and Pista GP R is the anchor listing. Tint availability splits across two listing variants in this group: one carries iridium, smoke and clear, and a second carries smoke, clear and gold. If a specific mirrored finish matters to you, open both listings rather than assuming the first one you land on is the whole range.
Photochromic and anti-fog insert versions both exist for this group, so it scores the full three shield types. For a helmet that spends time on track and time on the road, the photochromic option removes the need to carry a spare shield in a rucksack, which is a genuine practical gain rather than a marketing one.
Two existing guides go deeper on the individual shells. If you are on a standard Corsa there is a dedicated Corsa fitment guide, and the R variant has its own Corsa R fitment guide. The Corsa and the Corsa R are not the same shield, which is exactly why they have separate pages.
3. The Compact ST touring group: Compact ST, GT4, K1 and K1 S
The Compact ST is a flip-front helmet, and its shield group quietly overlaps the K1 family. Listings put the Compact ST together with the GT4, K1 S, K1 and K3 SV, which makes this the third five-model group. The overlap is real rather than a cataloguing accident, and it means a Compact ST owner has more options than the model’s relatively low profile would suggest.
The replacement visor for the Compact ST and K1 carries iridium, smoke and clear finishes. A photochromic version is listed for the same grouping, and there are two anti-fog insert listings, one grouped with the GT4 and one grouped with the K3 SV.
Flip-front helmets have a specific fogging problem worth naming here. The chin bar traps warm breath against the shield at a standstill, so a helmet that is clear at speed can mist the moment you stop at a junction. That is an airflow issue rather than a shield-quality issue, and an insert addresses it more reliably than swapping tint does.
There is a dedicated Compact ST fitment guide if you want the model-specific detail. One caution on ordering: some photochromic listings in this group also name the ILM 902, a different manufacturer’s helmet. That is a genuine shared fitment and not an error, but check the model list on the listing rather than the listing title.
4. The Pista and Race group: Pista GP R, Pista GP RR, Race 2 and Race 3
This group sits slightly inside the race group above and is worth separating because its photochromic and insert options are listed on their own. Four models are covered: Pista GP R, Pista GP RR, Race 2 and Race 3. The replacement shield itself is shared with group two, which is why the table shows it as shared rather than counting it twice.
The photochromic visor for the Pista GP R and Race 2 is the widest listing in this group, naming all four models. A matching anti-fog insert covers the same set, and there are narrower listings covering just the Pista GP R and Pista GP RR pairing.
Race 2 owners should read this group carefully. The Race 2 appears in the Pista listings but not in every Corsa R listing, so it is one of the models where the group boundary genuinely matters. Checking the named model list before ordering takes a few seconds and avoids the most common return on this marque.
A photochromic shield is a reasonable default for this group specifically, because these are helmets that get used across a wide range of light. A track session that starts under cloud and finishes in low sun is exactly the case an auto-tinting shield handles well. You can compare the full range on the photochromic visors page.
5. The New K3 group: New K3, K3 and K4
This is the group where most ordering mistakes happen, and it earns its place in the list for that reason rather than for its breadth. AGV replaced the K3 with a new K3 in 2023, and the two do not share a shield. Ordering the wrong generation is the single most common fitment error we see described on this marque.
The listings are separated deliberately. There is a replacement visor for the New K3 with its own photochromic and insert versions, and separate older K3 listings alongside a K3 and K4 insert. If your helmet is a 2023 or later purchase, you almost certainly need the New K3 parts.
How do you tell them apart without a receipt? The New K3 has a redesigned shield mechanism and a different vent arrangement on the chin bar. If you are unsure, the safest check is the shield removal action itself: compare it against the images on both listings before ordering, and if the mechanism does not match, stop and check rather than forcing anything.
All three shield types exist for the New K3, so once you have identified the right generation you are well served. The K4 shares an insert with the older K3, which is a useful piece of knowledge if you own both. This group is a good argument for keeping the model year written somewhere inside the helmet.
6. The K6 group: K6 and K6 S
The K6 covers only two models, the K6 and the K6 S, but it makes up for narrow breadth with complete depth and one unusual listing. All three shield types are stocked, and the group has a clean, unambiguous fitment with none of the generation confusion that affects the K3.
The replacement visor for the K6 and K6 S carries iridium, smoke and clear finishes. There is also a multi-brand shield listed as fitting the K6 alongside a KYT R2R and an MT V-14, which is genuinely useful if you run different helmets across the year. Several K6 anti-fog inserts are cross-brand in the same way, naming the Arai RX-7X and HJC C70.
The K6 is a lightweight road helmet that sees a lot of commuting use, and that shapes what is worth buying for it. A clear shield plus an anti-fog insert handles the year-round commute better than any tint choice does, because the limiting factor on a dark wet morning is condensation rather than glare.
The K6 S distinction is minor for fitment purposes since both are covered by the same listings, so this is one group where you do not need to identify your exact variant. That is worth stating plainly because the naming elsewhere on the marque is unforgiving. Browse the range of visors that fit the AGV K6.
7. K5 Jet and K5 Plus: the narrow group
Seventh place goes to the K5 Jet and K5 Plus, and the honest summary is that these are the least-served AGV shells in the range. Each has its own replacement visor for the K5 Jet and a separate K5 Plus listing, both carrying iridium, smoke and clear finishes. Neither has a photochromic option of its own.
The K5 Jet is an open-face helmet, which is the whole reason it sits outside the main K5 grouping despite the shared name. Its shield covers a different aperture and mounts differently. Anyone who has ordered a K5 shield for a K5 Jet has learned this the expensive way, and it is the second most common mistake after the K3 generation split.
For anti-fog on these shells, there is a universal insert listed for AGV helmets rather than a model-specific part. A universal insert is a reasonable fallback but it is a compromise: it is cut to fit a range of apertures rather than one, so seating is less precise than a part cut for a single shield. Check the aperture measurement before ordering.
The GT2 and GT4 sit adjacent to this group and are better served, appearing in photochromic and insert listings alongside the K1. If you own a GT2 or GT4, look at group three rather than this one. That is a case where the model badge is genuinely misleading about which shield you need.
What to check before you order
Four checks remove almost every fitment error on this marque. First, identify the generation, not just the model name — the K3 split in 2023 is the clearest case but it is not the only one. Second, read the full model list on the listing rather than the listing title, because the titles are truncated and the full list is where the answer lives.
Third, separate the shell name from the shield group. The K5 and the K5 Jet share a badge and not a shield, and the Corsa and Corsa R are likewise different parts. Fourth, decide what you are solving for before you choose a tint, because the tint that suits a bright July afternoon is the wrong choice for a dark commute.
If fogging is the actual problem, an insert will do more than any tint change. Our guide to stopping a helmet visor fogging ranks the available fixes, and the Pinlock-compatible anti-fog insert range covers the parts themselves. Pinlock is a third-party trademark and the inserts listed here are compatible parts rather than Pinlock-branded ones.

Tint, marking and UK road use
This section is why the comparison table has no road-legal column. In Great Britain the legal question is decided by the marking on the individual eye protector, not by the tint name, the colour, or the category a listing sits in. The Motor Cycles (Eye Protectors) Regulations 1999 prescribe grades in British Standard BS 4110 and require the protector to carry an approved certification mark of an approved body.
BS 4110 is the visor standard. It is a different standard from the one that applies to the helmet shell, and the two are frequently conflated in forum advice. We do not verify the marking on individual items, so no listing on this site is described as approved, certified or road legal.
One thing can be said plainly. Iridium and mirrored finishes transmit too little light to be legal for road use in the UK, day or night, and no softening of that with a daytime-only qualifier is accurate. Those finishes are sold for track and off-road use. The published guide to iridium and mirrored visor legality covers the detail, and the tinted visor rules for the UK cover the broader tint question.
The Highway Code adds a maintenance expectation on top of the legal test. Rule 83 of the Highway Code asks riders to check before each journey that the helmet visor is clean and in good condition, and rule 84 notes that scratched or poorly fitting eye protectors can limit your view, particularly in bright sunshine and in darkness. A scratched clear shield is a real hazard even though no marking rule addresses it. Browse clear visors or iridium visors according to where the helmet is actually used.
Frequently asked questions
Does one visor fit all AGV helmets?
No. AGV uses several distinct shield geometries across its range, and they are not interchangeable. The seven groups above are the practical map: within a group a shield swaps freely, and between groups it does not. The broadest single group covers five models, which is the closest thing to a universal fit across the range that exists.
Will an AGV K3 visor fit the New K3?
No, and this is the most common ordering error on the marque. AGV introduced a redesigned K3 in 2023 with a different shield and mechanism. The older K3 shield will not seat correctly on the newer shell. Check the model year or compare the shield mechanism against the listing images before ordering.
Can I fit an anti-fog insert to any replacement visor?
Only to a shield that is prepared for one. An insert seats against pins set into the shield, so a shield without those pins cannot take one. Most current replacement shields in the groups above are prepared, but the listing will say so. Never drill, trim or heat a shield to make an insert fit — that compromises a piece of protective equipment.
Are photochromic visors a good choice for UK riding?
They suit variable light well, which describes most UK riding. A photochromic shield darkens as ultraviolet light increases and clears again as it falls, so one shield covers a ride that starts in cloud and ends in sun. The transition is not instant, and the shield will not darken fully behind a car windscreen, so it is a convenience rather than a replacement for judgement about conditions.
How do I find the right visor if my AGV model is not listed?
Use the visor finder, which matches a helmet model to the shields that fit it, or open the AGV category and read the model list on each listing. If your helmet is a variant with a suffix such as S, Plus or Jet, treat that suffix as significant rather than decorative, because on this marque it usually indicates a different shield.
Choosing from here
The seven groups above are stable, but individual listings change as stock moves, so treat the model lists on the listings themselves as the final word. Start from your fitment group rather than your model name and the choice becomes much smaller and much clearer.
If you know your group, browse the full range of visors for AGV helmets and filter by tint. If you are not certain which group your helmet sits in, the visor finder is the faster route and will not let you order across a group boundary.
