A very nice, versatile helmet.
Been looking for a helmet to replace an HJC FS-15 Carbon, which was getting a bit old in the tooth, but was a great helmet, as far as I'm concerned (except for the cheap plastic on the vents#. I've also owned a Nolan N102 and a Akuma GhostRider full-face helmet in the past. I was tempted by the N43, but when I heard the N44 was coming out, I decided to wait and try it out. For reference, I'm currently riding a Tiger 800 w/ a Madstad windscreen, and have had the helmet for about 2 weeks / 300 miles. Overall, I'm pretty happy with it, but do have a few nitpicks.
Out of the box, the M-sized helmet #same size as my HJC# fit well. There is a bit more material around the ear pockets, which is weird at first, but not really uncomfortable. The fit and finish are much improved over my N102, and I like the graphics #which, of course, are a personal preference#. The chin guard does feel a bit close to my lips/chin, but not it's not that much closer than my other full-face helmets. If you have a more pronounced chin or jaw, I can see it being an issue for you, though.
The giant shield is great #mostly...#! Visibility is awesome, but it does tend to fog up easily in cooler weather without the Pinlock in. With the Pinlock, there's a huge area of non-fogged shield to look through, but at night there's a bit more glare off of lights. When inserting the Pinlock, be careful, though... I had one of the pins pop out and go flying off, so I had to call Nolan USA and get a replacement #they were great and sent me some new pins free of charge, btw!#. The sun shield, which I sort of considered a novelty, seems to work OK and comes down far enough, IMO, to not be distracting. One thing about the shield, though, is that there's no 'half-way' stop. If you want to scratch your nose while on the bike, if you don't push it all the way up #a relatively long throw with this shield# to where it is no longer protecting your eyes, it will drop down on your hand as you reach under.
Like on my Nolan N201, I do like the ratcheting chin strap, though the one on the N44 is narrower. Others have said this style strap feels like they're being garroted, but no problem as far as rubbing my neck for me.
On the bike, the helmet feels well balanced and the weight isn't noticeable #comparing to my carbon fiber FS-15#. The chin guard, because of the way it angles down a bit, tends to bump my shoulders when turning my head and catch on my jacket, but with the peripheral view I don't need to turn my head quite as much. Hopefully, I'll develop a 'technique' to minimize this.
Sound - I was hoping this helmet would be quieter than my current helmet, though I wasn't holding my breath. I would say it's about the same as my FS-15, though the tone of the wind noise is a bit deeper. There's a slight gap in the padding at the base of the neck in the back that seems to let in a lot of noise. Noise is also worse on the left side, possibly from a gadget I have mounted on my handlebars, but with my FS-15, I never noticed a difference from left to right. I guess I'll be continuing to wear plugs on anything longer than a short ride.
Ventilation - This is something I'm pretty disappointed with so far, as I was hoping for something better given all the big scoops on the helmet. The chin vent on the shield lets in a minimal amount of air, and I think it's pretty useless with the vent position of the shield letting in a good amount of air. The top vents don't seem to work much at all #maybe a bit as I tilt my head down?#, though hopefully that will improve as I break in the padding. I'll experiment more with the vents in conjunction with my windscreen in the spring. There is also a lot of air coming through the chin curtain, which may be OK in warmer weather, but I wish the material of the curtain was more solid now in the cooler months. A balaclava would probably solve this and the gap at the base of the neck mentioned earlier, though I didn't usually wear one with my other helmets unless it was really cold. BTW, out of all my helmets, I think my Akuma GhostRider vented the best.
I haven't tried mounting my SENA headset yet, but there are small 'pockets' carved-out of the foam liner under the padding for speakers. I don't know if the SENA speakers will fit, though... The clamp base might not work, though, and I will probably need to use the stick-on base option. I plan on using the wired mic, as I don't ever really plan on removing the chin guard and just wearing this as a FF helmet.
So basically, I was hoping for a 'better' helmet than my FS-15 in at least some ways. Though I'm generally happy with the N44, what I think I got was just a 'different' helmet. It's not any quieter, it doesn't #so far# seem to have better ventilation, but the view out the shield is definitely better, and the color is much more visible.
