Significant labor in constructing a carbon shell. Arai SK6 looks like a nice lid. You really looking to replace it?
I weightened my arai sk6 painted and with spoiler and was by 1640 gramms. Was today in a shop and tried out the bell rs7 k size L stock. Weightened it there and it was by 1460. But when i put it on my head the difference was huge. Felt alot lighter than my arai. And than they had a bell gp3 carbon which weightens 1310 with hans clips and this was like having only a hat on you. It was soo light. Even the difference is very small in numbers the feeling is enormous. And i imagine on track this difference will be more extreme. In the rotax senior class whith the d2 tyres the forces where not so high it was not a big deal but now on dd2 with the d5 tyres its a different world

Nice!
Well, my Arai SK6 is for sure the most comfortable helmet Iāve ever had, but yesterday I bought a Bell RS7K size M and yes, as soon as you hold it, you can tell it is lighter than the Arai, however my Arai helmet is size XL and the Bell helmet is size M, and they both fit perfectly, I donāt know if the sticker inside my Arai helmet is wrong and even if it says size XL, itās a size M as well? Although looking at both of them, the Arai looks bigger, at least on the outside.
I didnāt get to try the GP3 Carbon, looks great, but a friend of mine has a Carbon helmet, not the GP3, and the other day I was holding it and it was so light it felt like I was holding a balloon, I thought it was a toy, so I tried it and itās an unusual feeling, coz you donāt feel anything on your head, itās so light.
In any case, the Arai is still more comfortable than the Bell, not a lot more but enough that can feel it, nothing wrong with the Bell, feels good as well.
I guess if you drive a lot, especially if you drive nonstop for a long while, then it pays off to have a Carbon helmet, otherwise a regular helmet is more than fine, Iāve never had neck problems or anything that made think about buying a lighter helmet, of course I can understand the F1 drivers with those high G forces.
Mojo D5ās are awesome!
We gave here tracks with fast sweeping corners where you reach upto 2,5 g. And after half a day you feel your neck.

So, outside of simply design, construction does come into play when it comes to protection. Most carbon helmets will dissipate more of the impact and usually they will be mixed inner liner with Kevlar that has significantly better anti-intrusion properties then most other materials.

So finally got my Rs7 k the yellow painted version. It surprised how light it is. I got it in 59 and it weighs only 1420 grams.
Interestingly, I did 3 hours of racing with a āheavyā helmet because I had an external power supply attatched to the helmet, adding several ounces. I was expecting a neck workout from this but actually, was not able to feel a difference. That being said, lighter is probably better.
any updated thoughts on what super light helmets people like in here?
I have an old neck injury so light helmet really helps on our bumpy tracks. Agreed that even 100g which seems small is actually meaningful and you can feel it when you wear different helmets.
I tried a Bell RS7K carbon which is crazy light and fit great but the visor opening was tiny felt like driving looking through mail slot. Then I got a Bell M8 carbon for a season, and it was āokā but the way the visor attaches is total garbage and they strip because the threads are so low quality which is unacceptable for a $1,300+ helmet, if you change visors all the time I donāt see how you donāt end up with issues. The Bell rs7 had same visor system issues.
Sadly my carbon M8 got left on the side of the road accidentally when unpacking kid stuff out of the trunk on drive homeā¦
perfect helmet recipe for me goes:
- light as heck and carbon
- NOT a Bell
- quality system for swapping visors that wonāt break/strip like Bell
- visor opening is not super tiny
- max price $2,500
Any feedback or reviews on Stilo carbon helmets? seems like it checks the boxes and I like the way the visor can be driven just barely open but still latched down
Stilos are nice too and are very light. The eyeport is small though so try one on if thatās a concern. The nice thing is they offer a fairly reasonably priced carbon helmet which no other manufacturers really do other than Bell.

Have you tried zamp carbon fiber? Im still looking up on the weight. But its not breaking the bank for sure.
ok so just a quick update after ordering tons and tons of helmets, the carbon stilo ST5 in a size XL shell weighs 3.2lbs and the same helmet in composite weighs 3.6lbs, so you save almost half a pound by paying for the big premium for the carbon helmet. The large shell is 2.88lbs so my X large shell is noticeably heavier but I have a big head apparently. stilo st5 fits shape of my head perfectly also super cumfy. lot more expensive than Bell carbon helmets but feels obviously nicer more expensive product as well.
I found the stilo ST5 visor opening to feel wider than rs7 but I donāt have them side by side at the moment, Iād say they are about the same vertically. ST5 is smaller opening than M8 but maybe Iām just getting used to more serious race helmets but the ST5 seems fine to me so thatās the helmet Iām going with.
