Troy Lee Designs SE4 Motocross Helmet

The high-end and high-quality Troy Lee Designs SE4 Motocross Helmet is relatively expensive. You get what you pay for, and here you get maximum protection.

Who is This Product For?

The Troy Lee Designs SE4 Motocross Helmet is designed for motorsport enthusiasts willing to spend a good chunk of change for maximum head protection. This is a high-end helmet for anyone who puts safety first when riding motocross.

What’s Included?

When you purchase the Troy Lee Designs SE4 Motocross Helmet, you get a high-quality helmet with an SE4 Polyacrylite build, along with a MIPS brain protection system, contoured interior pads, a high-quality ventilation system, and a quick-release buckle system for EMS.

Overview of Features

When it comes down to it, the Troy Lee Designs SE4 Motocross Helmet has to be one of the best and safest motocross helmets around.

The most important thing to note is that it meets or exceeds DOT FMVSS 218 standards, ECE 22.05 standards, and AS/NZS 1698 standards. It has been certified through extensive testing.

One reason this r helmet is so highly rated for maximum protection is the SE4 Polyacrylite construction.

Without getting too scientific, this is a unique type of plastic, one of the most durable and impact-absorbing plastics out there. Compared to standard ABS plastic helmets, this is much better and offers more protection because of the solid shell.

Something worth mentioning is that although the Troy Lee Designs SE4 Motocross Helmet is as durable as it gets, it is also very lightweight, weighing just over 1,400 grams; it should be reasonably comfortable.

To help keep you as safe as possible, the Troy Lee Designs SE4 Motocross Helmet comes with MIPS. MIPS is a unique brain protection system that reduces rotational force to the head and the brain, for those who don’t know.

In layman’s terms, it stops your head and brain from absorbing too much rotational force. This can help prevent a litany of injuries, including concussions, brain and neck damage, and spinal injury. This is a fantastic feature, and you would wonder why all motocross helmets don’t have it.

Next, the Troy Lee Designs SE4 Motocross Helmet features an expanded polypropylene chin bar that is designed in a way so that if you fall on your face, your chin is safe and your teeth won’t get knocked out; this is something that happens quite often in motorsports when riders don’t have a good chin bar.

One of the coolest features here is the quick release system. There is an adjustable buckle so you can get a secure fit, but all helmets have this.

The neat part is that the quick-release system allows emergency responders to quickly and easily take the helmet off if you require immediate medical attention.

The Troy Lee Designs SE4 Motocross Helmet has 3D molded anatomically and ergonomically correct cheek pads that absorb impact and keep you comfortable.

The other cool part about this helmet is that it comes with an advanced ventilation system that features 10 air intake holes that force sweaty and hot air through 6 outtake holes in the rear.


In terms of getting the most out of the Troy Lee Designs SE4 Motocross Helmet, all you need to know is that there are 6 available sizes, and you need the right one.

Protection depends on a secure fit. To determine whether you need the XS, S, M, L, XL, or XXL, refer to the sizing chart.
