Lots of manufacturers produce helmets like the Schuberth J2. Basically, it’s an open-face helmet with a large, full-height, lift-up visor. I believe they are known in some circles as 'cruiser' helmets. And indeed they do seem popular with the Harley crowd.
We already do the Shoei J-Cruise 3, which is probably as good as one of these helmets gets, especially as we can use the new Shoei PFS (Personal Fit System) to get it to fit perfectly, but I think most manufacturers will have a helmet like this in their range. But if this is the style of helmet that you have decided that you want to ride in then the Schuberth J2 has a little trick up its sleeve that none of the others do.
And that is a removable chin bar. But here's the thing. Schuberth tells us that in terms of its strength in the various ECE 22-06 tests the chin bar meets the standard that would allow it to be classified as a full-face helmet. But for one thing! The chin bar does not meet the minimum requirements in terms of height.
The J2 has the same type of shell that is used on all of Schuberth's ECE 22-06 helmets. It’s constructed using their patented Direct Fibre Processing Technology that sees carbon fibre being used to reinforce other organic fibres.
The helmet features the Anti-Roll-Off System (AROS) that has been a feature of all Schuberth helmets for many years. It adds an additional element of reassurance that your helmet will never come off in an accident.
Schuberth claims that the J2 achieves an 88db rating at 100 kph on a naked bike. The company has endowed the J2 with a tighter neck roll, as in the C5 and their other helmets, in order to make the helmet quieter. And this will help, obviously, but the very large space between the bottom edge of the visor and the cheek pads is the weak point. Air is going to enter the helmet here, and air at speed, when it reaches the ears, is noise!
The company also talks about its ridged ‘Turbulators’ that run along the top of the visor. These are meant to reduce wind turbulence, and once again should serve to make the J2 quieter.
But we shouldn't get carried away. Schuberth has claimed the J2 is quieter than its competitors. And this might be the case, but the J2 is still going to be a noisy helmet. Let us compare Schuberth's 88 decibel rating for the J2 with the 85 decibels of the C5, for example. Now that increase does not sound like much, but decibels are measured using a logarithmic scale. So the three decibel increase actually indicates a doubling in the sound intensity, meaning that the safe 'exposure time' is halved.
It is suggested that exposure to sounds above 85 decibels can lead to hearing loss. At 85 decibels it is suggested that the safe exposure time is eight hours. At 88 decibels it comes down to four hours. In terms of understanding what this means, 85 decibels is equivalent to a noisy restaurant, a food blender, or a heavy truck. 88 decibels is what you'd experience driving a forklift truck.
We are not saying that Schuberth has not done a great job here. They probably have. And whilst 88 decibels may be great for an open-face helmet, it still constitutes a noisy helmet. And certainly suggests that if you’re going for a J2 you should wear earplugs.
There is one thing that mitigates in favour of the J2 in this respect. And that is that it will very often be worn by riders of cruiser-style bikes with large screens. And if that's the case then noise may indeed be less of an issue.
It is widely accepted that the mark of a properly premium helmet brand is at least three shell sizes. That's what you get with every Shoei helmet and with every Arai. With three shell sizes you have a better chance of getting a perfect fit, and you help avoid some of those instances where a helmet can look like an over-sized bowling ball on your head.
Like all Schuberths and all Shark helmets, the J2 only comes in two shell sizes. Now don't misunderstand us, the J2 will fit a lot of people. All the inner surfaces feel plush, and if your head fits, the J2 will be a very comfortable helmet to ride in. But two shell sizes is not the gold standard.
