What a helmets does
The helmet is the one piece of kit that is regulated, checked at scrutineering and, in an accident, the one doing the work. For UK karting under Motorsport UK the helmet must carry an accepted standard on its label, and for younger drivers the list is shorter and there is a weight limit.
A standard is a test the helmet passed — impact, penetration, retention — and the label inside proves it. Karting has its own standards because karts have no seatbelts and young drivers have lighter necks: the Snell-FIA CMR and CMS youth standards cap weight, while the Snell K series and FIA 8878-2024 cover adult karting. A shell and liner absorb one serious impact by deforming; after that the protection is spent even when nothing shows.
How to choose
1 · The standard for the driver's age
The rule follows calendar age, not the class.
How to judge it: Under 15, and all Cadet and Bambino drivers: only Snell-FIA CMR2007, CMS2007, CMR2016 or CMS2016, and the helmet must weigh no more than 1550g — it can be weighed at any time during an event. From the 15th birthday the list opens to Snell K2015, K2020, K2025 and FIA 8878-2024. A CMR2016 or CMS2016 helmet is accepted at any age, which is why it is the safe buy for a family. Car-racing standards FIA 8859 and 8860 are not accepted for karting, and motorcycle standards never are.
2 · Fit
A helmet that moves on the head does not protect the head.
How to judge it: Measure the head 2 cm above the eyebrows and just above the ears, twice, and use the larger figure against the maker's own chart. On: no rocking, even pressure with no hot spots, chin strap snug with at most one finger's clearance, cheek pads pressing lightly, and with the strap fastened the helmet must not roll backwards when the head tilts forward. Any failure on rocking, cheek pads or that roll test is the wrong size — do not try to break it in.
3 · Date and condition
Only one accepted standard currently expires, but condition and impact history retire a helmet regardless.
How to judge it: Read the label inside the shell, usually under the lining at the back or on the strap: standard, maker, serial. Of the nine standards Motorsport UK accepts in 2026, only Snell SA2015 has a date, 31 December 2026. Makers put working life at five to ten years from manufacture. Any impact at all ends it.
Compatibility. Full-face only, with the maker's own visor. The accepted list is Motorsport UK's, so a helmet legal elsewhere may not be legal here; the label decides, and the scrutineer can remove the sticker and impound a helmet with more than superficial damage.
Types, and the trade-offs
| Type | For | Against | Best for |
|---|---|---|---|
| Youth CMR / CMS | Legal at every age, light by rule. | Smaller shell range; the older 2007 versions are not valid internationally. | Cadets, Bambinos, anyone under 15, and families who want one helmet that stays legal. |
| Adult Snell K | Designed for karting, open-ended validity. | Not permitted under 15. | Drivers from their 15th birthday. |
| Adult FIA 8878-2024 | FIA-recognised for international karting. | Premium pricing. | Adults racing internationally. |
- CMR / CMS
- Snell-FIA youth karting standards with a weight cap, so a child's neck is not loaded by a heavy shell.
- Matters when: Any driver under 15, and every Cadet or Bambino. CMR2016 shells run up to a 59 cm head.
- Snell K2025 / K2020 / K2015
- The current adult karting standards; no expiry date set.
- Matters when: From the 15th birthday onward.
- FIA 8878-2024
- The FIA's own karting standard, accepted alongside Snell K.
- Matters when: Adult drivers who also race abroad; CMR2007 and CMS2007 are not recognised internationally.
- Weight
- Shell material decides it: composite and carbon shells are lighter than fibreglass.
- Matters when: Under-15s must be at or below 1550g; everyone benefits over a long day.

What this covers
This is a snapshot of kart helmets as listed by UK kart shops on 2026-11-01. PitHunt indexed 578 listings from 10 shops, covering 534 distinct part numbers. Of those, 27 are stocked by more than one shop, which is where a price comparison means something: the same manufacturer part number, different tills.
Prices are the shops' own listed prices in their own currency, captured by PitHunt's weekly scan. They are not quotes, they move, and the cheapest shop for one part is not the cheapest for every part. Each one links to the shop's own page so you can check before you buy.
The price range
Taking the cheapest listing for each part number, a tenth of them cost £20.00 or less, the middle of the range sits at £247.95, and a tenth cost £998.00 or more. The spread is wide because the category mixes small hardware with complete components, so the useful comparison is always like for like — the same part number across shops.
The widest gaps for the same part
The comparison ranks part numbers by the difference between shops in money, among parts listed at £10.00 or more — a big percentage on a tiny part is arithmetic, not a saving.
The largest gap in money is on Bell GTX3 Carbon Helmet: £956.52 at ZipNorth against £1,307.00 at the dearest of its two shops — £350.48, or 37%, for the same part number. The full list is in the comparison table above, ranked the same way.
A gap like that is not a judgement on either shop. Listed prices reflect stock bought at different times, different suppliers, and whether a shop is clearing a line. What it tells you is simply that for this part number, on this date, checking a second shop was worth the minute it took.
Which shops were cheapest most often
Across the 27 part numbers stocked by more than one shop, KKC Kart Components had the lowest listed price for 20 of them, followed by ZipNorth with 5. That is a count of wins, not a verdict: a shop that is cheapest on the parts you actually need matters more than one that is cheapest on average.
The honest way to use this is the boring way. Find your exact part number, look at every shop that lists it, and let the number decide. Name the part, and PitHunt lines every shop up cheapest-first.
Before you buy — the checklist
Buying used, check
- ☐PitHunt does not list second-hand helmets, following eBay, for the reason above: buy new, or a certified ex-demo direct from the manufacturer.
- ☐On any helmet, new or not: label present and legible with standard and serial; liner padding springs back; no cracks, no delamination, no scuffs that go through the paint.
Mistakes to avoid
- ✕Buying by class rather than by birthday — an X30 Junior aged 12 to 14 is on the under-15 list; the day they turn 15, mid-season, the adult list opens.
- ✕Buying a size up for growing room; a loose helmet fails the roll test and the protection with it.
- ✕Buying a used helmet. Its impact history cannot be verified, so it cannot be relied on for competition — and one knock that left no mark has already spent it.
Questions
›Does a helmet expire?
Only if its standard is withdrawn from the accepted list — in 2026 that is Snell SA2015 after 31 December. Otherwise the limit is condition: makers suggest five to ten years, and any impact at all retires it.
›My child is 14 and racing Junior — which standard?
CMR2016 or CMS2016 (or the 2007 versions), under 1550g. The adult list opens on the 15th birthday, not when the class changes.
›Can I use my car-racing helmet for karting?
No. FIA 8859 and 8860 car standards are not accepted for Motorsport UK karting at any age.
›Where do these prices come from?
From the shops' own websites, collected by PitHunt's weekly scan of UK kart retailers. Each figure is the price the shop listed on the date above, in the shop's own currency, before delivery.
›Why would the same part cost more at one shop?
Stock bought at different times, different supplier terms, and clearance decisions. None of that is visible from the price alone, which is why comparing the same part number across shops is the only fair comparison.
