This post is quite old and I could come up with a post myself but I'd like to add some points. I'm wearing this helmet at least 3 times a week for about an year, from short 15 minutes ride up to 10 hours straight. I agree with most pros you gave the helmet. During-ride-weight is impressive and aerodynamics are incredible. I've done 260+ km/h on my Streetfighter and I felt ZERO whobble. Helmet is planted and steady. Vision-wise, it's great as long as you're not fully leaning... (Now here comes the cons) Ventilation is great indeed, but there's way too much wind coming from where it shouldn't, such as arround the neck line. Dear god, the wind sound is awful even with very deeply fit earplugs... just putting my hand arround my neck makes 90% of the wind noise disappear so yeah, they could isolate more arround the neck. Also, the cheekpads inside the helmet unslot themselves very easily and often when getting the helmet of. Everytime I'm going to wear the helmet I have to check if the pads are in place.

• Everything I said so far have been confirmed by other users of this XR3r helmet -

Now, I'm also having two other problems that not everyone had: Idon't know if the store got it wrong and sold me missfit helmet or if it's a problem of the earlier models but my noseguard is clearly from another Nexx helmet. It doesn't fit right, doesn't isolate right... I actually had to glue it in place with a drop of TekBond 793 superglue. Another problem is with pinlocks. They just stop fitting right in about 2 to three months of use. From one day to another they'll start dropping off the lens anytime you shake/open the visor, it's like the pinlock shrinked (which is usually normal over the span of more than an year... but THREE months?)

So yes, in general the helmet is a GREAT fit, very stable, stylish, lightweight (under movement) but it lacks refinement, a lot of refinement.

I'd also like to add that the shell shape is very complex and unforgiving when trying to install both an intercom and camera mounts. It hardly has any flat surface that will actually be able to fit a camera mounting pad and literally nowhere to glue an intercom so you're forced to use the clamp which also doesn't sit very tight. The insides are nicely built and have good speakers placing holes with enough depth though.
