Here is my review of the Nolan N-102 I posted on another forum...(warning, review not Nolan N102 friendly)
(Most of this applies to wearing the helmet on a sport bike)
Nolan N-102 review after 12,000 miles
Summary: If you're sensitive to weight, price and noise, you will want to look elsewhere.
Helmet Fit and Comfort: This helmet is obviously built for large round heads. The helmet fit my head for the most part but the foam over the forehead area was to tight and caused pressure that would give me a headache similar to a sinus headache after wearing it for 2+ hours. I fixed this by attacking the foam with 80 grit paper to make more room for my “Neanderthal man” like forehead but the weight of the helmet still gives me a headache after a long days ride. The latch for the chin bar closes properly 8 out of 10 times. Sometime the chin bar comes down and has a vague feel to it so you have to re-open it and shut it again. I expected more from Nolan, after all my el cheapo Sysmax did not have this problem.
Air Flow: As with most helmets the airflow inside just isn’t enough on hot days and way to much on cold days. Not sure what can be done about this but “helmet vents” are somewhat of a joke in my opinion anyway. They do nothing more than cause a lot of noise.
Visor: I really do like the visor, the armor coating on the lexan really does a great job preventing scratches. The one thing I DO not like is the latching system. It doesn’t seem to have a “positive” shut so at times when riding a question if the visor is all the way down or not. Mostly because of all the air leaks (more on this later).
Sun Shield and Nolan Fog Resistant System: The sun shield is a great addition and could be useful on any helmet in my opinion. Being able to flip it down on sunny days and up on cloudy or night riding is a big plus! Now the “Nolan Fog Resistant System” is something I didn’t clue into when I first purchased the helmet. When a manufacturer includes an accessory with this name a signal flare should go up. This helmet will fog over in the blink of an eye on days where NOHTING should fog over. Its one of the many complaints I have about this helmet. I did try the NFRS and it works “OK” but I think having to apply this Band-Aid (all the time because it will fog on a 90 degree clear summer day) to this poorly designed helmet is a big minus!
Retention Strap: While it seemed cool at first I have grown to hate the retention strap. Its HUGE and in cold weather when your jacket is zipped all the way up and or you have a neck gator on this thing turns into something similar to baseball jamming you in the adams apple. Give me a strap with D rings over this thing any day!!
Noise and Aerodynamics: Oh my god, time for the review to go south! How noisy is this helmet? Well I think not wearing a helmet at all would be quieter! Honestly why would Nolan release a helmet this loud when its supposed to be setup to integrate a blue-tooth module for communications? I am sure glad I didn’t buy the whole shebang when I first purchased the helmet or I could really be upset. This is absolutely the loudest helmet I have ever placed on my head and the sad thing is the main reason I purchased it was to install the blue tooth for phone and intercom applications. This would be nearly impossible for anyone to use unless they find themselves behind a big windshield. On a sport bike? Forget about it, you are not going to be able to hear the speakers. I am sure the noise is a direct relation to the amount of airleaks this helmet has. Honestly it is so bad you have to wear glasses under the shield because at 80mph there are odd blast of wind that hit you in the eyes and eventually dry your eyes out or worse yet blow foreign matter into your eyes.
Aerodynamically this helmet is great unless you have a passenger. For some odd reason once you add another helmet within a few feet aft of the Nolan it starts to bob and weave all over the place. You start to feel like you’re a prize fighter trying to dodge the opponent’s jabs.
Weight and Price: I consider myself a fairly burly guy and didn’t think an extra few ounces would make much of a difference. Holy cow was I wrong, the extra weight really starts to “weigh” on your at the 2 hour mark. I will never make this mistake again, weight is important! At a $279.00 MSRP I feel this helmet is over priced by about $200. In fact I am pretty sure I wouldn’t buy another one for $50 so take that for what its worth.
Conclusions: Well it’s a pretty helmet but other than that I wouldn’t wish this thing on anyone. Would I recommend to a friend? No, would I buy another one? Hell NO! The purchase of this helmet as been the largest waste of money to date on motorcycling gear.
