HJC FG-X Grand Duke Helmet 4.5 5 4 4
Great impression so far! I haven't had a chance to ride yet, it's winter here in MI, but my first impression is that this will be a great helmet. It's lighter than my old HJC and fits better too. Revzilla shipping and service was great as well! February 2, 2016
great helmet....airflow excellent I bought this at the Philly store. I was sized up properly by the owner? who really knew what he was doing. I was riding dual sport in the pinelands with my street helmet and cooking in it. The fit is excellent. I take a large and the large fit perfectly. Airflow is excellent and my head stays cool despite the high temps I rode in. Quality of the helmet is excellent. I like the fact that the helmet is DOT and Snell certified, as not all moto helmets are. The helmet quality is top notch too. For the money, great helmet. Great store too with excellent, knowledgeable service. June 22, 2015
High end at low price My head fit only shoei quest and this one. The helmet is made of fiberglass, very light. The air flow is present and not loud. No bizzare air turbulance. The cushion is very present and hold the head tight. The look is very sleeper in black mat. With a decent pair of google, you have a 500$ equivalent setup. May 1, 2015
Great value Execelent bang for the buck here. This helmet looks great, is very comfortable, and is very good quality. Not the lightest helmet out there but very competittive. You will probably have to spend another $100 to get any lighter. Im very happy with the weight of this one. The size seems to be slightly large so if your head measures close to in between sizes, maybe try the smaller one. October 20, 2014
