I've been doing as much research as possible for the last 4+ months on helmets. I wanted a full-face helmet that has the best airflow while maintaining a "Sport Touring-style" helmet. I preferred to have a drop-down sun visor. Colors didn't really matter, so as long as it wasn't white, hi-viz (they fade fast!), or any of those teenage-like/sports bike rider/themed graphics. I hoped for something "quiet" but again, doing research, even the best reviewers were reminding me that you're on a motorcycle and there really isn't a "quiet" motorcycle helmet, only "quiet-er" helmet!
I have a few helmets already of different brands and styles. I didn't want to break the bank either as some of my best helmets are the Bilt brand (Cycle Gear) helmets and they're extremely well-priced.
So, after searching and searching the best one I found for what I was looking for was the HJC RPHA-70 ST. I already have 2 HJC's from years ago when I bought my 2003 Volusia. They aren't bad helmets but they're full faced and very noisy. (Plus very outdated at this point)
Anyway, these helmets go for $360-$380 for the standard, single-color helmets. So I rode down to my dealer in Tampa. They only had the RPHA's in the Grandal style, which is $400+. After speaking with my parts guy (he always takes care of me!) I told him I wanted the RPHA but just didn't want to pay the extra $$$ for a funky painted helmet. Since he didn't have any solid colors in stock he said he'd sell me the Grandal for the solid color price and give me a 10% discount. I said, "Box it up!".
I settled on the black and white HJC RPHA-0 ST Grandal. Final cost after taxes - $375.00
(Yeah, I cought some bugs on the way home!)
This is the most expensive helmet I've ever owned/bought. But let me tell you, on the ride home it was awesome! I had all the vents open and could immediately feel on my face where the vents were blowing. This helmet has 6 intakes and 2 exhaust vents. It comes with a Pin lock lens and a really thick helmet bag. It also has a velcro-attaching chin skirt for the cooler days. There are reflecting pads attached to the bottom. When you hold this helmet up and look at it from behind it's really noticeable. Also a unique feature is the underneath of the ear pads is a material that helps to catch the helmet from sliding off your seat should you set it there. (Something I never thought of!)
Also noticed immediately...the weight! Man, this thing is light!
All in all, my wallet's definitely lighter (at least for my tastes!) but I'm liking this helmet. I was nice and cooled on the ride home, given that I'm in 90 degree heat here in Tampa, FL. The air flow is great and the noise was actually quiet-"er" than any of the current helmets I own. I like that you can either lock the visor down or keep it open a tad bit to allow more air in.
