For a motorcycle ride to be enjoyable the interior of the helmet needs to be comfortable. And for a budget helmet to be comfortable, the fitting of the helmet needs to be picture perfect. Or you might end up with a helmet that you don’t want to use for a second time.
The interior of this particular helmet seemed pretty nice and good enough for an entry-level helmet at least. If you get your perfect sized one, you can use this helmet without any discomfort. However, don’t expect it to be as good as the premium Arai XD4 though, that’s a top-notch helmet.
For the sizing of this ILM 606v helmet, this helmet comes from Small (55-56 cm) to XX-Large (63-64 cm) sizes. One good thing about the ILM company is they are actually responsive to the customer’s request. So, if you somehow end up with an unfit helmet, they will send additional pads, which will hopefully solve the problem.
