How to Choose The Right Size Motorcycle Helmet
Today, we're going to talk about helmet fit and selecting the right size helmet. First off, It's really important that a helmet fits properly so it can do its job. Its primary job is to manage energy in an impact. It's an energy management system. If the helmets too big, it's not going to be able to do that effectively. Another byproduct of having an ill-fitting helmet, one that's too large, is it's going to be a lot noisier than a helmet that fits properly. The reason for that is it's just not going to seal right around the neckroll area. So you're going to have a lot more road noise.
The first thing you need to do when you're getting ready to order a brand new helmet, is take a measurement. The best way to do it is with a cloth tape. Not everyone is going to have this at home. If you don't have this, a cloth sewing tape is going to be a great way to go. Truth be told a lot of people probably don't have that. Most people when we have a tape measure, your tape measure looks a lot like this. Wrapping this around your head it's not really going to work. What you can do, is you can use a string, a shoelace, right. Mark it, stretch it out, compare it against the tape measure. And get your measurement because it's really important that the measurement is accurate. We're going to show you where the tape should be and how to do it in just a minute. But do it more than once until you find the biggest measurement.
Next up is head shape. We have essentially three different head forms that we've identified. The first and most common, especially here in North America, is going to be the intermediate oval head shape. What we have there is, it is slightly Longer front-to-back, than it is side-to-side. The next head shape is going to be long oval. Long oval is longer, front to back, and a little narrower side to side than what we see with the intermediate oval. The last one, and this one's really not as common, is going to be the round oval. Where the head shape is noticeably rounder than the first two that we talked about. Head shape without a doubt influences the way that a helmet fits. If you know you're round oval or extremely long oval, give us a call. Shoot us an email. We're going to help point you in the right direction to help get you a good comfortable safe fitting helmet.
We're to go ahead and go just above the eyebrows. Remember the goal is to get the measurement at the biggest possible point. Got him dead at 56 cm. One of the things you want to avoid doing is in the back, don't let the tape dip excessively low or excessively high. You want to try and keep it fairly level, don't go to either of the extremes. We're going to go ahead and going to do this again. Just make sure we've got a good accurate measurement. There I've got him just a little bit over 56. And there again pretty much right at 56 cm. Using the Bell Helmet size chart, size small is 55 through 56 cm Size medium is 57 through 58 cm. For Josh, based on his head shape and the measurements that we achieved I would recommend for Josh a size small.
What I want to talk about right now is the right way to put a motorcycle helmet on. Remember too, the way your head is shaped, you have to get the smallest part of the helmet here. The opening over the thickest part of your head which is going to be just above the eyebrows. The easiest way to do that Is you grab both retention straps like this and spread it apart a little bit. It's going to spread the cheek pads apart you tip it and you pull it down like so, over the top of your head. You can clearly see that it took a little bit of effort in order for Josh to get that on. And that right there really is the key. You don't want to have any real focused pressure points. Now there's a couple things we want to do to verify the fit of the helmet. We want to see if we're able to lift it off. The last thing that we want to do is the roll off test. You grab it at the back, and we're going to try and roll this helmet right off the top of his head.
