The Moto-9 Carbon Flex is Bell’s top of the line off-road helmet, representing the best Bell has to offer in comfort and performance while also incorporating injury prevention technology that’s on the leading edge. This safety tech comes by way of their progressive 3 layer EPS system.
With 3 layers of EPS as opposed to the standard 2 layers, the Carbon Flex can better compensate for low, medium, and high levels of impact by having an EPS layer designed for each. There’s also a limited "slip zone" built into the liner which means impact forces that hit the helmet at an angle will be better distributed throughout the helmet’s energy absorbing materials.
This makes the Carbon Flex one of the most protective helmets available, but it’s also one of the most comfortable because the lightweight carbon fiber shell keeps your neck from fatiguing, the soft interior liner disperses all potential pressure points, and the ventilation scheme is just as solid as the standard Moto-9, even with the additional impact foam layer.
Progressive layering – A first-of-its kind, three-layer impact liner designed to manage energy from three potential impact scenarios: low, mid and high-speed.
Adaptive fit – Segmented construction, automatically conforming to a rider’s head for a better fit and more predictable energy management.
Rotational energy management – A "slip zone" within the impact liner allows for subtle movement between the inner layers and works to reduce rotational energy transfer from angular impacts.
Exclusive Magnefusion™ Emergency Removal System (MERS) cheek-pads.
New and Improved Exclusive Magnefusion™ magnetic strap keeper.
Industry-leading Five-year warranty.
Snell M2015, ECE, and DOT approved.
Ventilation – With the new segmented and flexible liner in the Moto-9 Flex, Bell was able to add to the proven Velocity Flow Ventilation system to make an even cooler helmet.

Hands down one of the best if not the best helmet on the market. The BELL MOTO-9 CARBON FLEX has some pretty awesome features to it aka the magnetic check-pads & D-ring clip (the D-ring magnet can be annoying when putting/taking-off the helmet) but it is great when it's on the tab that it's supposed to be so it's not annoying while ridding. It's got a built in roost-guard on the chin bar or front of the helmet the eye port is pretty big, big enough to fit the -PROSPECT- goggles from "Scott". All around comfortable helmet it's 100% spot on the money as far as true to size i mean my head measured just about 21-22 niches when measured from the largest portion of the back to about an inch from the eyebrow & size small fit me perfectly (S55 cm-56 cm21 5/8" - 22"6 7/8" - 7"). i absolutely love the FLEX's unique "A first-of-its-kind, three-layer impact liner" witch is meant to save your brain when in a crash the 3 layer are different densities to manage low medium & high impacts while having a slip plan in between each of the layers in other words it's BELL'S version of the "MIPS" & to top all of the cool things i got an unbelievable good deal on my helmet i know even at full msrp* that this helmet your money is well spent & it's worth every last cent you spend. overall 5 stars on this helmet thank you Rocky Mountain ATV*MC
Awesome ft. Bought a large. My head measures 58cm just above the brows. I have a funky knob on the back of my head which the liner compensates for. I notice more goggle fogging on humid rides than my old 6d, but the fit is better. Best of all, I have a $20.00 credit due to a price drop. Rocky Mountain is #1.
By far the most beautiful helmet I have ever worn. It’s just a little tight for my head but I think I’ll get used to that quickly. I got this carbon Flex moto 9 at 1/2 price. The helmet feels like a new pair of socks, absolutely love it. You better buy them up if they are still out there for the price I got, do not miss out.
great helmet. RM pricing was insane on this item. The moto 9 carbon flex fits great and is better than my previous helmets especially for the way it is weighted. I feel like they nailed the fitment perfect and it does not have you feeling like the helmet is weighted funny or that your nose is too close to the beak. great product. top notch
Great protection and love the air flow I get with this helmet. I ride a cruiser in Florida so the air flow is a must and I get plenty with this helmet. The big plus is I have a full helmet but not the closed in feeling I get with most road full face helmets.
This helmet fits me so well. The opening is a little snug, but once it’s on, it fits like a glove. Very comfortable and I almost forget that I am wearing a helmet. I'm a large in Shoei, Fox, and other Bell helmets and Large in this helmet was perfect for me.
The most comfortable, best protecting helmet IMO. My previous was a 6D. I always felt safe, but it wasn't the most comfortable. I had one pretty good smack on the ground so I figured I would go back and try a Bell. Just love it
Not the best for big heads but great quality and comfort
I have this helmet in the carbon black and had some issues initially with sizing but realized I had to go from a fox Xl to a bell 2xl. I find my face is relatively close to the beak as well but that seems to just be the design. I purchased this helmet as a spare as I initially had wanted this color combination so I really can't say anything bad about the helmet.
My review is based on the fit,comfort as I have not had a chance to actually wear it on a ride. I have owned 3 different Bell helmets in the past (2 Moto 5’s and a Moto 9) and loved them all. This carbon flex helmet appears to have much more padding than my previous Bell helmets. I will be able to give better reviews after a few rides and after I break it in. Judging by the performance of my previous Bell helmets, I’m sure I won’t be disappointed. Also I got a great deal on this helmet, 52% off.
Awesome helmet, this is the most comfortable, and best venting helmet I have ever owned. My last helmet was a fox V3, my only complaint would be the cheek pads are really tight, I bought smaller pads for $ 19.95, and now it fits perfect, if its tight when you get it, try pulling the cheek pads out and trying it on before you send it back.
I bought this helmet when it was on sale as a Christmas gift to myself, and I'm super happy that I did. It's amazingly comfortable, looks great, and protects my head great as well. I would recommend this to anyone that wants a helmet that will protect their head well.
Very impressed with how light it is and how much air circulation and has and is very comfortable!
I have been looking for a new helmet for a while it is been along time since I wore a Bell. When I tried the Bell helmet on it was amazing it was so much lighter than my Fox V3. I’ve only One time with it and it is amazing super comfortable. I wear eyeglasses when I ride it is the easiest helmet I’ve ever had to put my glasses on. Make sure you try one on before you buy I wear a medium but I needed a large. Looking for my next outing which will be on 1/5/19 our annual New Year’s ride. Thanks RM. MATT
ALL THE HELMETS I HAVE OWNED ARE IN SIZE SMALL I HAVE A 22 1/8 SIZE HEAD AND MEASURED FROM THE EYE BROWS. THIS HELMET IS A LITTLE TO SMALL AND HARD TO SLIP ON REALLY GETS MY EARS. I ALSO FEEL LIKE THE HELMET JUST MITE NEED TO BRAKE IN I HAVEN'T IT FOR MORE THEN A DAY OR GONE ON A RIDE WITH IT. OVER ALL THE HELMET IT SUPER LIGHT AND BELL HAS ALWAYS MADE GREAT HELMETS
