What's this?

Arai Signet-Q Pro Tour Helmet

The Signet-Q Pro-Tour takes all the favorite features of the RX-Q and Signet-Q helmets to create a whole new series based on Arai's many innovations, including the radical new Pro Shade System which operates as both a peak and as a sun shade. The Pro Shade System is a small peak that is locked in position. Unlocking is easy; just pull the Pro Shade System forward, then it can be flipped down with a flick of the hand to act as an effective sun-visor. 

On the outside, the Arai Signet-Q Pro-Tour Helmet looks very similar to it's namesake, the Signet-Q, but features several innovations on both the inside and outside. A longer shell shape on the Arai Signet-Q Helmet gives 5mm more space front to back allowing for a larger number of heads to fit comfortably. The shape of the Arai Signet-Q Pro-Tour Helmet releases forehead pressures and eliminate hot spots for a more comfortable fit every time.  This shape works best for riders with a long oval headshape.

Additional Features of the Arai Signet-Q Helmet

  • Pro Shade System for dual sun-blocking capabilities
  • Eco-Pure Liner is anti-microbial
  • Ear pockets have been redesigned to better accept communication speakers for a more comfortable fit
  • Both the top vent set and side exhaust cowls are direct carryovers from the RX-Q Helmet
  • Brow vent ducting redirects to flow air across the temples

  • Elongated shell adds 5mm from front to back
  • Long-Oval shape helps prevent “Hot-Spot”
  • Multi-Density Single piece EPS liner
  • Removable, replaceable, washable interior
  • Dry-Cool Surface material for rapid displacement of heat and moisture away from your head and into the ventilation airflow for added comfort while riding and a quick dry between rides
  • 5mm peel-away temple pads adds another level of customization, giving the helmet interior a little extra width when needed
  • Enhanced for customizable micro fitment interior without the need to purchase extra interior components
  • FCS (Facial Contour Support) cheek pad design
  • Innovative and exclusive spring support adds just the right amount of pressure when needed while being worn

Arai Signet-Q Pro-Tour Helmet 4.8 5 363 363
Exceptionally Comfortable! I purchased this helmet to replace an 8 year old Arai Profile. I ride almost every day so comfort is important. When searching for the replacement I was open to other brands, I just wanted a flat black helmet that would look good with a dark smoke visor. I had first purchased an AGV AX-8 Evo Naked for the looks. That helmet fit horribly and I ended up returning it within the hour I opened the box (thanks Revzilla!) and buying this Signet-Q Pro Tour; mostly because it has the long-oval shape that I needed. The Signet-Q provides a VERY comfortable fit. My first ride with it was about 8 hours and I had no issues with fit or comfort. My head circumference measures 58.5, so I went with a large and it fits nice and snug. With the helmet, I also purchased a dark smoke pinlock visor along with a regular SAI dark smoke face shield. The SAI face shield looks much better on the helmet. The only problem is that when removing the pinlock face shield, the Pro Shade comes off with it as it is attached to the face shield. The black frost helmet has the 'murdered-out' look to include minimal decals and all of the decals are black. I am very happy with the purchase and Revzilla had the best price that I could find.

Excellent design I purchased the Signet-Q 4 months ago and have worn it commuting and all day rides since then. It fits my oval head perfectly with no hot spots and ALL of the features of the helmet work exactly as designed. It is one of very few products that I've purchased that I am not at least a little disappointed with. I read that another reviewer had trouble with the tinted visor not staying up. After you raise the external, tinted visor you have to push it rearward and it locks into position. When you want to lower it you have to pull the tinted visor forward out of its detents then slide it down. The only time mine has come down was before I knew I had to snap it back into its detents. Ventilation is as described. It is easy to get a comfortable gentle breeze through the helmet when it is hot (I've ridden from 55 to 104 degrees.) and to close the vents and lower the chin guard while riding in cooler weather. Removal and reinstallation of the cheek pieces is a little tricky the first time, but easy to do if you repeat it a few times. (I watched an online video.) I've removed and washed all of the internals several times. If it fits your head, the Signet-Q is a first rate product. August 27, 2016
Wife is Happy...Great Customer Service!! My wife and I both ordered a Signet Q Pro, hers a medium that fit perfect, mine was an extra large and I couldnt close my mouth (fish lips)...just tooooo small....I measured myself again and found me to be a 2X Large....I called the next day and Brittany was awesome..apologized and sent me an email for the return...since it was my first they waived the return shipping of $7.95. I trie to order it in a 2XL but they didnt have the same Black to match the wife's Signet so I did some research and went with the Defiant Pro Cruise, that was on a Thursday and tracking says it will be here on Monday...GREAT Customer Service all round and look forward to purchasing more in the future...$1200.00 for two helemts and wife didnt blink an eye... 16 HD Ultra Limited August 21, 2016
Great helmet, comfortable, light. The fit of the ARAI is great, but that's subjective. The build quality of the interior is great. It was a good fit for me out of the box, but if I wanted to tinker and add/remove foam layer for real or perceived improvements, there were a lot of options. The ARAI is lighter than my previous helmet (which had a polycarbonate shell). I have a naked bike and at speed the signet-q is well balanced with no buffeting. Mounting a sena 3s was ok, but it was slightly difficult to route the cables on the ARAI. The speakers end up very close to my ears, if they were a millimeter thicker they'd bother me. I always use earplugs, but appreciate low noise level anyway, especially when listening to podcasts. The ARAI is much quieter yet better vented than other helmets I've had. Mounting the pinlock shield took some trial and error, but the next time it will be easier. Taking the shield off is not as easy as with other helmets, but I don't do it regularly so I don't mind. I wear glasses and the ARAI is perfect for that. I considered a competitor helmet because the fit for my head was comparable with the Signet-q, but my glasses did not stay where I wanted - deal breaker. The brow vents are cheap and hard to operate with gloves on at speed, it feels like they'll break off at some point. Weird, considering the overall quality of the other helmet parts. August 30, 2016
Finally a helmet that fits I have a long oval head. Frankly I never knew I did utilize I was talking to a local dealer that sold Arai. The Signet Q fit my head so well. I had a neotec and while it was a good helmet I never use the modular feature and so that was wasted. This Arai is super comfortable, quiet and I finally have a helmet that fits my head really well. Great customer service by Revzilla as always. July 8, 2016
SPecial size for narrow heads No one makes a helmet that fits someone with a long oval head like the Signet-Q from Arai. The fit and finish of this helmet is beyond any other manufacturer. I've had HJC, Bell, Nolan and nameless brands and none of them fit a long oval shaped head. Finally, excellent finish, great graphics and replaceable pads for when your sweat just permeates the originals and they have to be replaced. Different tinted wind screens and durable designed movable parts. Great helmet August 19, 2016
Worth Every Penny! I've owned several brands of helmets and this is the absolute best. The Signet-Q model is designed for riders with long-oval shaped heads and the comfort is outstanding. Very quiet, great airflow and wide field of vision. The brow vents in the face shield flow air right where you need it on hot days. Super lightweight and the Diamond white finish is awesome. Arai helmets may be a little expensive but you get what you pay for in terms of safety and features. August 16, 2016
I have finally found a helmet that fits I am already an Arai customer for life. This is a beautiful, high quality helmet. The details and small design features are great and tells me that this company actually cares if they make a great helmet. The airflow is amazing and is engineered into the helmet, unlike most helmets that just have a holes drilled into them. TRUST THE SIZE CHART. I was skeptical but I measured and ordered an XL and it fits perfectly. My last helmet is a Schuberth and it is a 3X, so I was expecting to return for a larger helmet. Aria knows what they're doing. I also have used modulars for 6 years and I have gone back to a solid helmet. No regrets. The modular is overrated for features and adds weight and expense. Love this helmet. August 16, 2016
