So I was looking at the HJC RPS-10 helmet and from the reviews I've read about it, it's a really nice helmet. One thing I heard is that it is designed to ride in the tuck position, well riding a Harley I don't ride in a tuck position so I was wondering if any will it affect the way the helmet is designed to work or does it not really matter? Air flow?
 
At 40 mph I doubt that any aerodynamic traits of the helmet will come into play. so buy with the confidence that you will never go fast enough for the helmet to make an impact in airflow dynamics. enjoy your new helmet..

M-e-o-o-o-w.


All helmets are different, in different positions. The more vents, wings and do-das, the more they change depending on your head position. Get a simple full-face thing and be happy that it will hold your brains in one place to be found later.
 
I find that taking a karate type stance, knees slightly bent, a mild forward list aids in the tuck. I then simultanously stuff the bat and ball team to the back whilst popping to attention as if an officer has just entered the room. This tuck however, aids in Drag. Cheers.
 
Do your other Harley friends know you're trying to get a full face helmet..? :laughing
 
I'm sure my shoei x-11 is more aggressively designed than the HJC and I never tuck; you'll be fine.
 
maybe it has a little more to do with how far the back of the helmet contours around the back of the neck area and how far down that area of the helmet goes? I have an X-11 and a Corsair and the corsair fits a bit tighter around the back of the neck and you feel that constriction a bit more when you try to contort your your neck to look up from an aggressive tuck... also the visor upper opening is higher up on the shoei and that helps with unobstructed vision while looking "up" from the tuck...

Sounds good bradah! Yeah the Shoei hurts my head, just don't fit me right!

Ok thanks for the advice bradah, I'm just looking for a light weight helmet and the Shoei is a no go, haven't yet tried the Arai yet I hear they are pretty loud. I like a couple other helmets like the Kali Naza and the Bell RS-1 guess I just have to find the one that fits the best.

The shoei qwest is designed for more sitting upright riding. Nice helmet btw.

I think this might be a helmet that would suit you better than the RPS-10, but I do recommend just buying whatever feels best on your noggin.

+1 on the Qwest - just got one last week - dark grey matte. Really like it - fits me well, and good control of airflow - vents open I can feel cool air on my head; vents closed, very little air inside.

Works great for me on my Road King. :thumbup

I own an RPS-10. I've owned Arai's, Suomy's and Shoei's. I can honestly say the RPS-10 is the best helmet of all of the above, for racing.

It is not a good "street" helmet. The venting isn't really adequate unless you're in a tuck, it's a little more confining than a regular Shoei or street based Arai, and it's not as quiet.

The price point is there, the protection is there, the comfort is better than all of the above, but I wouldn't wear one as a street helmet. It was designed by HJC and Ben Spies as a race helmet and that's what it's great at.

No
Here is why and you answered your own question
I don't ride in a tuck position

if the Helmet was designed to spec as a ofr racing Tuc means your chin is on the gas tank or your in a far more aggressive stance on the bike, leaned in, head closer to the bike not sitting up like on a Harley. Open your Harley up lean in and down "TUC" then you may see the difference.

TUC is a form of becoming as small as you possibly can on your bike, reducing the drag and increasing slip stream. Dirt Trackers do it, Road Racers do it, Hell even the person on the High Way I see most everyday like he is on the banks of Daytona. me my belly gets in the way, justget a helmet that meets and or exceeds all DOT/SNELL and so on and your comfortable with.
 
If the RPS-10 fits you well, consider the FS-15. It's the outgoing model, and preceded the RPS-10 as the top-line HJC helmet. The fit is identical, but the venting is better and it's a slightly more street-worthy helmet. Mine "wants" to be tilted forward a smidgen more than AC-12 I just replaced, but it's a perfectly good street helmet with no race pretenses.
