The visors that fit KYT helmets are not one part per helmet. They fall into seven shared-shield fitment groups, and inside a group a single replacement shield covers every shell in it. Work out which group your lid belongs to and the buying decision stops being a guess.
This guide ranks those seven groups by fitment breadth — how many other KYT shells share the same shield, so how many helmets in your garage one purchase can cover. Every figure below was read off our live catalogue listings for each model group. There are no ratings here and no sales figures, because ranking a shield on anything other than what it physically fits would be inventing a number.
The short answer
- The NF-R group is the widest. Its shield is listed as fitting five other KYT shells — the NF, NX, NXR, NX-F and GP — so it is the group most likely to cover two helmets at once.
- The TT Course group has the most choice. Nine listings, and a single replacement listing carrying fifteen separate tint options, which is the widest tint range on the brand.
- The R2R group has the most auto-tinting options. Two photochromic listings between them offer four options, more than any other group here.
- Breadth and tint choice pull in opposite directions. The three widest-fitting groups — NF-R, NXR and NX — carry no photochromic listing at all. The four narrower groups all do.
- Every one of the seven groups has a pin-style anti-fog insert listed. That is the one column where the groups do not differ, so it should not decide your choice.
Why one shield covers several KYT shells
A visor is not held on by the shape of the helmet. It is held on by the side mechanism — the ratchet plate, the pivot boss and the catch that the shield’s hooks drop into. Two helmets built around the same mechanism take the same shield even when the shells look nothing alike and sit in different price brackets.
That is why fitment groups exist and why they cut across a manufacturer’s own model naming. The NF-R and the NXR are marketed as different helmets to different riders. They use the same shield, so on our catalogue they sit in the same group and a single listing names both.
It also explains the failure mode. A shield that is close but not right will mount, and it will even close — but it sits proud at the top edge or fails to seat on the seal, and the first motorway run tells you about it in wind noise and a draught across the eyes. The Highway Code is direct about the consequence: rule 84 warns that scratched or poorly fitting eye protectors can limit your view when riding, particularly in bright sunshine and the hours of darkness. Fitment is a vision question, not a cosmetic one.
So the group matters more than the model name. If you know the group, you can buy across it with confidence; if you only know the model name, you are relying on a listing to mention your exact shell. Our visor fitment dataset records the shared-shield groups across every brand we carry, and the KYT category hub is where all fifteen KYT model groups are listed.
Visors That Fit KYT Helmets: The Seven Fitment Groups Compared
Read the table on the third column first. That is the ranking criterion — the number of other KYT shells listed as sharing the same shield. The last two columns are what the group actually offers you once you are in it.
| # | Fitment group | Other KYT shells sharing the shield | Listings in the group | Tint options on the widest listing | Photochromic listed | Pin-style insert listed |
|---|---|---|---|---|---|---|
| 1 | NF-R | 5 — NF, NX, NXR, NX-F, GP | 9 | 9 | No | Yes |
| 2 | NXR | 4 — NF-R, NX, NF, GP | 6 | 10 | No | Yes |
| 3 | NX | 3 — NF-R, NXR, NF | 5 | 8 | No | Yes |
| 4 | TT Course | 2 — TT Revo, TTC | 9 | 15 | Yes | Yes |
| 5 | GP | 2 — NF-R, NXR | 4 | 10 | Yes | Yes |
| 6 | R2R | 1 — R2R PRO | 5 | 9 | Yes | Yes |
| 7 | TT Revo | 1 — TT Course | 5 | 12 | Yes | Yes |
Groups four and five are tied on breadth at two shells each, and TT Course takes the higher place on listing count. Groups six and seven are tied at one shell each, and R2R takes the higher place because it carries two photochromic listings rather than one.
1. NF-R — the widest fitment group on the brand
The NF-R is the group everything else in the KYT sport range hangs off. Across our listings its shield is named as fitting the NF, the NX, the NXR, the NX-F and the GP — five other shells, more than any other group here. If you own two KYT lids, this is the group with the best chance of covering both from one purchase.
Nine listings sit in the group. The broadest is a replacement shield listed for the NF, NF-R, NX and NXR together, carrying eight tint options that run from clear through silver and black to the deep iridium finishes. A second listing covering the NF-R, NX and NXR adds seven more, weighted towards the iridium end. A third pairs the NF-R with the NX-F across nine options, and a fourth covers the NF-R and NX.
What the group does not have is a photochromic listing. Nothing in the NF-R family auto-tints, and that is the price of its breadth — the shells that share this shield are the ones our range covers with fixed tints only. If auto-tinting is the feature you actually want, the honest answer is that you are looking at the wrong group, and the photochromic visor range will show you which fitments do have one.
Anti-fog is well covered. Three separate pin-style inserts name the NF-R, including one shared with the GP and NXR and one shared with the NX-F. Browse the group at KYT NF-R visors and inserts.
2. NXR — the same shield, one shell fewer
The NXR sits inside the NF-R family rather than beside it. Its shield is listed as shared with the NF-R, NX, NF and GP — four other shells — and every one of those relationships comes through a listing that names the NXR explicitly rather than through inference.
Six listings cover it. Two are the wide NF-R family shields already described. The third is the bridge listing that ties the GP, NF-R and NXR together, and it is the single most useful item in this part of the range: ten tint options, including clear, silver, black, the rainbow finish and four iridium variants. That one listing is why the GP appears in this group’s fitment list at all.
The practical read is that an NXR owner shops the NF-R shelf. There is no meaningful NXR-only inventory to hunt for, and treating the two as one group will find you more stock and more tints than searching the model name alone. That is exactly the behaviour the shared-shield structure is supposed to produce.
Like the rest of the family, the NXR has no photochromic option in our range, and two pin-style inserts name it directly. If you have never fitted one, our guide to fitting a pin-style anti-fog insert covers the tensioning step that most people get wrong first time. The group is listed at KYT NXR visors and inserts.
3. NX — the family’s entry point
The NX shares its shield with the NF-R, NXR and NF: three other shells. It is a narrower reach than the two groups above it, and the reason is simply that fewer listings name the NX than name the NF-R.
Five listings cover it, and four of them are shields already met higher up the table. The one that is specific to this end of the family pairs the NX with the NF-R across eight tint options, including clear, silver and a deep black smoke as well as the iridium finishes. In practice an NX owner has the same shelf available as an NF-R owner, minus the NX-F pairing.
This is the group where checking the listing text genuinely matters. Because the NX sits at the edge of the family, some listings name it and some stop at the NF-R and NXR, and the ones that stop short are not a fitment you should assume your way into. Read the model list on the listing rather than trusting the family relationship, and if it is not named, treat it as not confirmed.
No photochromic listing exists for the NX, and two pin-style inserts name it. For a wider view of which helmet makers have insert coverage and which do not, see our comparison of anti-fog insert fitment across eight helmet makers. The group is at KYT NX visors and inserts.
4. TT Course — the most choice in the range
The TT Course shares its shield with the TT Revo and the TTC — two other shells, which puts it fourth on breadth. On every other measure it is the strongest group here, and for most riders it will be the more useful one to be in.
Nine listings cover it, matching the NF-R group on volume. One of them is the widest single listing on the brand: a replacement shield with fifteen tint options, spanning clear, a clear green, four separate iridium finishes, gold, purple, two blacks and a deep rose blue. A second listing shared with the TT Revo adds eleven more options, and a third shared with the TTC adds twelve.
It also has a photochromic listing, in three finishes. That is the feature the whole NF-R family lacks, and it is the reason a TT Course owner has a genuinely different set of choices from an NF-R owner despite both groups carrying nine listings. If you are weighing an auto-tinting shield against a second fixed-tint one, our comparison of photochromic against tinted visors works through when each makes sense.
Anti-fog coverage is the deepest of any group: five pin-style inserts name the TT Course, one of them shared with the HJC C70. Browse it at KYT TT Course visors and inserts.
5. GP — the bridge into the NF-R family
The GP is an unusual entry because it belongs to two places at once. It has its own listings, and it is also named on the bridge shield that covers the NF-R and NXR — so it reaches two other shells while sitting outside the family’s core.
Four listings cover it, the smallest count in this table. Two are GP-specific: a replacement shield in ten tint options and a photochromic listing. The other two are the shared GP, NF-R and NXR items — a replacement shield in ten options and a pin-style insert — and they are what stop this group from being a dead end.
The practical consequence is worth stating plainly. A GP owner should search both the GP shelf and the NF-R shelf, because half the inventory that fits the helmet is filed under a different model name. Searching only the model name is how a rider concludes we do not stock anything for their helmet when in fact four listings do.
The GP does have a photochromic option, unlike the NF-R and NXR it shares a shield with — a quirk of which listings exist rather than a difference in the mechanism. Before buying one, our guide to checking photochromic visor fitment is worth two minutes. The group is at KYT GP visors and inserts.
6. R2R — narrow fitment, the most auto-tinting options
The R2R reaches one other KYT shell, the R2R PRO, which puts it near the bottom on the ranking criterion. Judge it on that alone and you would pass it over, which would be a mistake, because it leads the brand on the feature most riders ask about.
Five listings cover it, and two of them are photochromic: one for the R2R in a clear and a blue finish, and one shared with the R2R PRO in a clear and a red. Four auto-tinting options in a single group is more than the TT Course, the TT Revo and the GP carry individually, and it is the only group here with more than one photochromic listing.
The fixed-tint listing is also the odd one out in the range. Alongside the usual black, silver and iridium finishes it carries an anti-blue lens and a brightening lens — two options that appear nowhere else in the KYT groups. The R2R is also the one shell here that reaches outside the brand: a multi-fit replacement shield names it alongside the AGV K6 and the MT V-14, so a rider with two different makes of helmet may be covered by one part.
One pin-style insert names the R2R. If clear vision in cold weather is the priority, the clear visor range and the group at KYT R2R visors and inserts are the two places to look.
7. TT Revo — the TT Course shelf, seen from the other side
The TT Revo shares its shield with the TT Course and nothing else, which places it seventh on breadth. That single relationship, though, is a relationship with the deepest group in the table, so the reach understates what is available.
Five listings cover it. A TT Revo replacement shield carries twelve tint options — clear, silver, rainbow, two revo silvers and golds, a rose red and a pink gold among them — and the shared TT Course listing adds eleven more. Between them a TT Revo owner has more fixed-tint choice than an NX or NXR owner, despite sitting lower on the ranking.
There is a photochromic listing for the TT Revo, in a single finish. It is the thinnest auto-tinting option in the range, so if a specific photochromic colour matters to you, check it is in stock before committing rather than assuming the choice that the TT Course or R2R groups offer.
Two pin-style inserts name the TT Revo, one of them the shared TT Course item. The group is at KYT TT Revo visors and inserts.
How to choose, and what to check first
Start with the mechanism, not the catalogue. Take the existing shield off the helmet and look at the hook pattern and the ratchet plate, then compare that to the photographs on the listing. A shield that matches the mechanism will seat; one that does not will sit proud however carefully you fit it.
Then decide which of the two columns you are actually shopping on. If you own more than one KYT lid, breadth is worth more than tint choice — being in the NF-R group means one spare shield covers both helmets and you carry one part, not two. If you own one helmet, breadth is worth nothing to you and the TT Course, R2R and TT Revo groups will give you more to choose from.
Be careful about assuming your way across a family. The NF-R, NX and NXR share a shield, but individual listings stop at different points in that list, and a listing that does not name your shell is not a fitment we have confirmed. The model list on the listing is the fitment statement; the family relationship is only a hint about where to look.
Tint, and where you actually ride
The tint columns above are the most tempting part of the table and the part most likely to lead you into a shield you cannot use on the road. The KYT groups are weighted heavily towards iridium and revo finishes — in the NF-R family those finishes make up the majority of the options on every listing — so it is easy to end up with a garage full of shields that are all track items.
The usual answer is to run two: one clear or lightly tinted shield for road and commuting, and one darker shield for track days and bright summer riding. Swapping takes a couple of minutes once you have done it once, and it costs less than compromising on either end. It is also why the breadth column matters more than it first appears — a wide group means both of those shields are available for the helmet you already own.
On tint, the constraint is legal and it is worth being blunt. Iridium, mirrored and dark-smoke finishes are never road legal in the UK, at any hour of any day, and the revo finishes that dominate the NF-R family are in that group. The legal test is the marking carried on the individual eye protector: the Motor Cycles (Eye Protectors) Regulations 1999 prescribe eye protectors by a British Standard grade together with an approved certification mark of an approved body, and they also require that a protector does not fly into fragments if fractured.
We do not verify the markings on individual items, and we make no claim that any visor we sell is approved or certified. So treat the darker finishes as track and off-road items, and keep something clear or lightly tinted for the road. Our guide to iridium and mirrored visors and UK road use goes through this properly, and the iridium range carries the same warning on every listing.
Finally, buy the insert with the shield. Every one of the seven groups has a pin-style anti-fog insert listed, they are far easier to fit to a shield that is off the helmet, and fog is the failure that ruins a winter commute rather than the one that ruins a track day.
Frequently asked questions
Will one visor fit both my KYT NF-R and my NXR?
Yes — that pairing is the core of the widest group in this guide. Two separate replacement listings name the NF-R and the NXR together, and a third names them alongside the GP. Buy from the NF-R group and one spare shield covers both helmets.
Do the TT Course and the TT Revo take the same shield?
They do. One replacement listing and one pin-style insert listing each name both shells, which is what puts them in the same fitment group. Each also has model-specific listings of its own, so it is worth searching both names to see the full range available to you.
Can I run a pin-style anti-fog insert on a photochromic visor?
It depends on whether that particular shield carries the pins, and it is not safe to assume. A photochromic shield and a fixed-tint shield in the same group are different parts, and only one of them may be drilled for an insert. Check the listing for your exact shield, and see our guide to pin-style anti-fog inserts for what to look for.
Are iridium and revo finishes road legal in the UK?
No. Those finishes transmit far too little light to be legal for road use in Great Britain, and that does not change between day and night. They are track and off-road items, and the legal test is in any case the marking on the individual eye protector rather than its colour.
How do I find out which fitment group my helmet is in?
Look up the model name on the KYT category hub, which lists all fifteen KYT model groups we carry, then open the listings under it and read the model list on each one. If your shell is named, the fitment is confirmed. If you would rather work from the helmet, our visor finder takes you from make and model to the parts that fit.
Where to start
If you know your model, go straight to the group above and read the listings under it. If you are not certain which shell you have, start at the KYT category hub and work down. Shipping is free, and orders normally take 5–10 business days to arrive, so it is worth ordering the spare shield before the weather turns rather than after.
