MX helmets, 509 or F4?

[adubs916]

In the market for a new lid and like the 509 Carbon C2 and the F4. Anyone have opinions on them? I currently have a MX style so I know what to expect as far as how they should preform, just looking for input on quality, likes or gripes. Also am looking for a "neck gaiter" that attaches to the bottom of the helmet and not around my neck to prevent wind from coming up and hitting me in the chin/mouth. thanks for any advice

I run a 509 evolution, with 509 sinisters an goggle fan an love the set up. Light an not much wind coming through mine an I stand up 90 percent of the time

509 goggles seal up perfect with the 509 helmet. Im running the polarized aviators and love the combo

I just got this one and it is awesome. It is my 1st snow x helmet ever. The breathvox is soft material and does not pinch my face. It is the lightest helmet on the market and I used Scott goggles with it an no air leakage only through the vents.

It even has an integral camera mount that does not stick up when no camera attached.


The MotorFist Dominator Helmet is unlike any other helmet on the market today. The dominator is the only helmet in the snowmobile industry to feature the Patented Composite Fusion Plusâ„¢ technology. composite fusion Plusâ„¢ technology incorporates unique pyramids of different foam densities inside the helmet shell, providing rigidity where needed for protection and softer materials next to your noggin'. This patented pyramid design along with the fusion of the protective foam to the shell is the solution to optimize shock absorption, spread energy, and control the deceleration created by an impact. In other words, don't leave home without it! And that's just the safety part - it also only weighs 1250 grams! Lighter than most carbon fiber helmets, you will experience less fatigue without breaking the bank!

Features:
•New matte black with tonal Motorfist logos
•PRANA™ FRP fiberglass shell with COMPOSITE FUSION™ plus construction
•Dual density CONTEGO™ EPS liner
•Weighs just 1250g
•Integrated airflow system
•Antibacterial, removable, washable liner
•"Pop-Out System" breakaway visor design
•Meets or exceeds AMA, FIM, CCS, WERA racing standards
•Safety certifications include ECE22.05, DOT (FMVSS 218)
•Includes premium helmet storage/travel bag
•Includes breath box
•Includes adhesive free helmet camera mounts

Airoh Aviator from Airoh America. At 950 grams, I would argue that it is the lightest helmet on the market today. ECE22.5 rated (the only rating requiring random sample testing from each production run ... not just a one time thing). Great ventilation - almost too cold ... you will not overheat in this helmet. I run with Smith Optics fuel googles and they completely fill the face opening. No sealing issues whatsoever.

Hjc make a great helmet and has much more experience than 509 does in making helmets.

X2
Fly Racing is much nicer than 509 and a lot more bang for the buck. Still running 509 sinister x5 goggles with it though and they fit and seal great. Love my 509 goggles but the fly helmets are a nicer product for the money. I run a flat black F2 carbon solid

From Airoh's website:

WEIGHT: FROM 980 G.
SIZES: XS (53-54) - S (55-56) - M (57-58) - L (59-60) - XL (61)


Their extra small helmet weighs 980g.

Normal human sized helmets will be heavier.

It's still very light though

You're splitting hairs between the 509 C2, MF Dominator, and the other sub 1100g helmets on the market today.

The EPS liner (foam) is a big part of the safety factor which is where I believe MF has an advantage. I personally use both the MF helmet and the C2 and like both. The 509 Sinister X5 seals perfectly inside/against the 509 cheek pads which goes a long way to keeping your face warm.

The other thing to consider is that both 509 and MF specifically engineered their helmets for cold weather (venting) while HJC and pretty much everyone else simply takes their dirt bike helmet (which are designed for MAX AIRFLOW!) and installs a breath box in it... they vent too much and run much cooler than necessary.

Hjc make a great helmet and has much more experience than 509 does in making helmets.

509 partners with one of the largest helmet manufacturers in the world to build their helmets.. they do not own the helmet factory... much like many brands out there.

Yes, afx makes 509 helmets. Afx is not known to make world class helmets.

The afx helmet is really no different in design from the other sno x helmets as far as air flow. I've been wearing MX helmets on sleds for so long I cannot remember, 15-20 years of trail use. Every one of these have been MX helmets with breath boxes added at most. I wear my MX helmets even when it's cooler than most will go out snowmobiling. I can recall several -25 degree without wind chill days, and I've never been cold.

509s marketing dept has done a good job, as people assume its made specifically for snowmobile use.

How are you staying warm in an MX helmet at temps that low? Certainly there has to be small cracks that bitter cold air is entering bare skin. Right around 10 degrees is the cutoff for me. What is the trick to wearing the MX helmet in very cold weather?

The label in my 509 Helmet says made by Tong Ho Hsing which is also known as THH. If you look at the THH website it looks the same as the TX-23.

Maybe AFX doesn't make their own helmets either.

Well thanks for all the feedback. Seems like many strong opinions, one way or the other. Just like anything, you hope to be satisfied with the product when you plan on using it for many years. That Airho looks really cool, and also expensive.
After researching many brands I decided to go with the Scorpion VX-34. They seem to be pretty well respected especially in the superbike and moto x world, and their price point works for me. I'll report any disappointments if any arise.
