In this article we talk about the lightest dirt bike helmets on the market today.


Long motos and long single track riding really take a toll on your neck and shoulders, we all wear helmets because it’s safe and we want to protect the ole brain in case of a quick exit.

Now, what if we could ditch that old heavy and crusty helmet that we have had for 20 years with a new lightweight SAFER motocross helmet?

We are talking…

The Lightest Motocross Helmet

The Lightest Enduro Helmet

The Lightest Trail Riding Helmet

Why do you need a light motocross helmet?

To alleviate all that pressure on your neck and head.


If you are like me and have a few half-numb fingers so you went to see the doc and the first thing he asks if you have landed on your head a few times…

Sound familiar?

I have a pinched nerve in my neck that has scar tissue wrapped around it from too many head and neck impacts.

This has resulted in half numb fingers and a feeling of a needle slowly being shoved deep into my neck, which starts to show up around an hour into riding.

My 6D helmet, Fly Racing Helmet, Answer Racing helmet, and Fox Racing helmet would put too much weight on my neck and head resulting in a pinched nerve.

This sucked.

All the motocross helmets I had were too heavy.

I thought it was a fitness thing, and did lots of shoulder and neck strengthening and also stretches.

While this helped it did not take nerve pinching away.

So, had the bright idea….

What if I could find a lighter motocross helmet?




I first went to downhill mountain bike helmets. Hell, these guys hurdle themselves down some pretty gnarly terrain (Red Bull Rampage) at speeds I cannot comprehend.

While there were tons of REALLY tempting options I decided to stick with the ECE, DOT, and SNELL rated lightweight motocross helmets.

Most of the lightweight motocross helmets listed below weigh under 3lbs. Now some of these are for the medium-sized helmets so judge accordingly.


Who makes the lightest motocross or dirt bike helmet?

Personally, I have the KLIM F3 Carbon Helmet because it’s super light and not as expensive as the other helmets. The Airoh Aviator 2.2 is REALLY light but it’s an old model which means that it’s being replaced with the Airoh 3.0 helmet which is not as light.


I would love to try the Fly Racing Carbon Prime motocross helmet as I have liked the Fly Racing helmets that I have had in the past.
