The Stilo ST5 CMR Karting Helmet benefits from the latest technology some of which are the same as the other ST5 helmets in the range. With looks that are almost identical our top of the range ST5 Zero helmets as used in Formula 1 by Valtteri Bottas.

The ST5 CMR is also being used by young British kart racer of the year, Harry Thompson in both his Red Bull UK and European 2018 programmes, and Taylor Barnard in his European exploits.

Manufactured in a Kevlar carbon construction, it's not only lightweight but very strong. Stilo's ethos for motorsport helmets: safety, comfort and functionality are paramount and from a company that is only produced motorsport helmets you can guarantee that there is no compromise in what they do.

The Stilo ST5 CMR has an improved interior giving an excellent fit with extreme levels of comfort due to its dual density interior foam lining - once worn you'll never change back. The ST5 CMR helmet has to be used before you truly appreciate the levels of comfort. The tried and tested, the smooth black lining has a proven durability and a finish that looks great which is why it is in the ST5 CMR Karting helmet. 

The Stilo ST5 helmet range has a visor design with a central visor locking system, a feature that will really benefit karters. This new symmetrical visor offers excellent vision and the centrally located locking system has dual opening positions allowing adjustment for the visor to be slightly open for extra airflow, this preferred by some karters in damp conditions or left completely sealed. More importantly in both of these positions, the visor is locked and will never fly open.

The Stilo ST5 CMR comes with a 3mm thick FIA F1 standard visor - adding a dramatic improvement in safety. Available in a large range of different finishes and tints, we also have coloured iridium options that have been added for a totally bespoke finish. In addition, a double glazed option is available for racing in wet and cold conditions to prevent misting up issues.

There are also a full range of spoilers available for any aerodynamic adjustment that may be needed, but also giving the helmet a great look.

Available in gloss white or radical matt black exterior finish, the ST5 CMR is homologated to the very latest Snell CMR 2016 standard.

This model is the latest specification Stilo ST5 CMR which has the redesigned interior lining.


This is a new product for 2023, therefore stocks are beginning to arrive in the UK in the early part of the season. If you have a specific date you require this helmet for, please contact our sales team when purchasing, and we will be happy to advise.

Helmet Fit

Stilo Helmet Sizes

Stilo helmets are available in different shell sizes within the range of full face and open face helmets. ST5 helmets (full face) come in two shell sizes: small and large. The small shell covers all sizes from 54 (XS) to 59 (L). The large shell is size 60 (L+) to 64 (XXXL) The only exceptions to this are the ST5 CMR junior karting helmet which is only available in a new reduced size (narrower) small shell from 54 (XS) to 59 (L).

In Venti WRC, WRX and Trophy (open face) models, Stilo have developed a third (medium) shell size to keep mass and weight as minimal as possible for the most popular of sizes, 59 and 61. So now, for this range, 54 (XS) to 58 (L) are in a small shell, 59 (L) and 61 (XL) are in the new medium shell and 63 (XXL) and 64 (XXXL) are in the large size shell. Another development from Stilo in the new Venti range is that for the first time, Carbon, 8860 and Zero models are all available in the largest size shell, something not previously available in the outgoing models and this is also a size that other open face helmet brands do not offer.

Stilo Venti and ST5 helmets generally are a little tighter fitting than some other brands, so do bear this in mind when choosing your helmet size and speak with us if you need some help on this.

With the new Stilo Sport range of clubman open face helmets, there are two shell sizes, XS-M are covered by the small shell size and L & XL are covered by the large shell. One point to note is that the internal linings of the Stilo Sport range are a different fit to the WRC helmets, and the fit is a little more relaxed and are more true to size.

How To Measure Your Head

At Nicky Grist Motorsports we understand the importance of a well fitting helmet. Get it right and you are on a fast track to optimum performance, but get it wrong and you’ll suffer distractions and discomfort that can put your safety at risk.

The key thing to remember is not to simply take the circumference measurement and buy a helmet based on that size. We need to look at the width and length of your head also, as that does affect the helmet size you need.

To measure your head as accurately as possible and to help us provide you with the optimum fit, please measure as shown below and make a note of your sizing to send to us. Always wear a balaclava when taking head measurement for a helmet as the extra 2-3mm does make a difference to the circumference measurement and it also presses your ears nice and close to your head.

Head Circumference

1. Circumference

Measure around your head with a tape measure. This must be above the ear and while you are wearing a hood (if you use one).

2. Length

Using callipers or similar device, measure the front to back of your head. This needs to be the furthest away points.

3. Width

Again use a tool of fabricated device to measure the width of your head at the widest points.



These are quite a specific tool and we appreciate that not everyone will have a set lying around. If you are stuck, you might be able to fabricate something, but please get in touch and we can advise you further.
