INVENTORY Five Reasons It’s Time To Replace Your Helmet…and What to Buy Next.In partnership with You should replace your helmet every five years, and sometimes sooner. Here are some ways to determine when — and how — to buy a new lid.

There are several reasons to wear a motorcycle helmet, and just as many to keep in mind when it’s time to replace one. And if you’re in the market for something new, Revzilla is currently offering some enticing deals from several brands in multiple categories.

Why Wear A Helmet?

For the simple reason that your brain matters to you and your loved ones. With so many choices in so many styles in so many colors and shapes, “it’s uncomfortable,” “it’s too hot,” or “it’s uncool,” are no longer valid reasons to avoid the number one thing that could save your life in the event of an accident. It’s never been easier to buy something that provides comfort, protection, and looks great no matter what you ride. Plus, on a hot day, a properly vented helmet can actually keep your head cooler than a helmet-less one. 

Do I Really Need To Replace My Helmet Every Five Years Or So? Why?

All helmets come with a manufacturer’s stamp, typically on a sticker placed on the inner shell. Reasons for replacing the helmet include: 

1. You Dropped It

Repeated dropping can damage the inner EPS (expanded polystyrene) lining of your helmet. It may not be visible on the exterior, but damaging the EPS can compromise the helmet’s ability to protect you. If the helmet has been impacted in an accident, you should replace it immediately.

2. It’s Outdated

Every year there are noticeable improvements as helmet technology evolves. After five years of wearing the same helmet, you will be amazed at the new features that a new one can offer, like stronger materials, lighter weight, better optics, and a quieter interior.

3. It’s Seen Some Foul Weather

Rain/moisture and extended sun exposure are the main reasons helmets degrade. If you commute daily in all weather, replacing your helmet regularly is recommended.

4. You Ride in Extreme Climates

Riding in extreme heat, humidity, or extreme cold cause the expansion and contraction of materials which can affect your helmet’s lifespan.

5. It’s Been Hit with Road Debris

Cleaners, fuel, high speed road debris, and other commonly encountered materials can degrade your helmet.

Where Do I Begin? And How Much Should I Spend?

As for a budget, an old adage still holds true: if you have a $10 head, buy a $10 helmet. For those who value their heads — and everything literally and figuratively attached to it — we’ve compiled a list of excellent choices below to help you decide. 

How Do I Measure My Head?

Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, repeat for good measure and use the largest measurement (usually in centimeters). Revzilla has also made the work easier for you by listing which helmets fit best for each head shape. If you don’t know your head shape, simply ask a friend to take a picture of your head from above (it’s for a good cause) and reference the chart shown here. And don’t forget to flatten your hair down as much as possible as not to obscure your domes natural curves.

01 Schuberth C4 Pro Merak

This modular helmet is extensively tested and aerodynamically optimized for both stability at speed and low weight to minimize fatigue on long tours.

An exacting amount of resin and heat are added under high pressure, yielding a shell of superior strength that is no thicker in any one area than it needs to be.
