just bringing this back up.....OP how do you now rate the Touratech one since you will have bedded it in ?
I like it. The biggest downside is that it presses against my forehead which I begin to notice after about 90 minutes with it on. After about 2 hours this becomes unbearable so I find I have to stop and take the helmet off for five minutes or so then start over. I've only used it in the ADV configuration (peak and visor) and the peak does not get grabbed by wind blast at motorway speeds with the screen on my LC fully up (it's OK with the screen down too but I have to have a slightly downwards tilt of my head to stop the peak getting grabbed). With the screen up, I can only feel the peak get grabbed when I look over my shoulder at these speeds. For lower speeds it's fine. I guess I'm around 5'8" if that helps.
I can also wear my glasses underneath it without and problem, they slide in and out with no problem, although the downside to this is they can move a little when on the move but I don't find this an issue (my race rep helmet holds them firmly so they don't move at all, but they're much harder to put on with the helmet on).
Ventilation - I don't really notice any incoming air from the vents on the top of the helmet, unless I tilt my head a bit, then I can feel it blasting in. Maybe the screen deflects so well, this is why I don't notice it. The mouth vent seems OK. I wear the chin curtain as I found that it was really breezy around the lower face when I bought (plus it was colder then too).
Build quality looks good around the shell, although the chin curtain doesn't really snap in place on the provided lugs - on one side it just sort of hangs there but is secure enough. When I first got it and put in the dark visor, I was a bit disappointed about the quality of the visor mechanism. It didn't seem very robust, but I've had no issues with it and everything works as it should, so nothing to be concerned about.
Overall I'm very pleased with it, it looks the part, and has the bonus of being used in different configurations (road and dirt in addition to ADV). I really need to do some experimenting with forehead pressure, maybe by using the extra padding that came with it, as this is the biggest downside, and I've started to take a paracetamol with me now to increase my initial ride time! Any suggestion on this greatly appreciated!!! ;-) I should also ay my race rep helemt also gives me the same headache problem, but I can ride longer with that on. Maybe I just have a weird head!
I guess I've probably covered about 2000 miles in it now, not that I've been counting. I hope that helps :-D
