The Shoei RJ Platinum offers excellent true-to-size fit and finish. A top notch, Snell and DOT approved, open face helmet that can't be beat. Dennis Kirk is THE place to get this helmet, you know right from the start if your size and color selection is in stock, unlike many of the other on-line stores who just order it and typically results in several extra days for delivery.
This helmet is compatible with intercom and communication system with generous ear pocket space.
I've owned and used a wide range of helmets from various manufacturers and this is THE best...don't sell yourself short or compromise your safety...Shoei is certainly a winner and a world class product.
I had been searching all over for a half helmet to replace my old HJC. None of the new ones fit my oversized coconut; they may have said "large size" but were all too narrow or sat on top of the head. So after looking this over I made the leap to an open face - took a little getting used to after years of half helmets, but the RJ is very comfortable, and lightweight for its size. I wear a 7 1/2 hat normally and the XL helmet size fits me just fine.
I usually wear a full face helmet, but when it gets really hot out I like more air movement. I bought this helmet because I didn't want to compromise safety. It's both DOT and Snell Certified. It is also the most comfortable helmet I've ever owned.
