Need to buy a new helmet in the next month or so. Totally torn between a modular like a Schuberth C3 (waiting for the Pro to come out) and a dual sport Arai XD4. Modular Pro's: Handy flip up the face part for talking while stopping, riding at lower speeds, etc. Purportedly a very quiet helmet Very nicely integrated bluetooth and internal antenna Internal flip down sun shield Pin lock visor included Con's: Questionably not as safe as a full face No visor for shading in early morning/late day sun Venting/air flow Price Dual sport Pro's: Wide eye aperture for visibility Excellent venting Visor for sun protection Cons: Noisier Colder to wear in bad weather Have to pay extra for a pinlock screen Wind grabbing visor when head checking Resonance in dirty air Am I missing anything? This will be my only helmet. I tend not to ride when it's truly cold and nasty out, so if I get caught out in weather, it'll be by accident. It gets very hot here in the summer, venting is important. I'll be doing some off road riding, but the majority of my riding will be on road, at city street type speeds with some highway cruising. I'm leaning toward the XD4, but I'm concerned about the buffeting and wind grabbing the visor, as well as how much noiser it is vs the Schuberth. Anyone have both helmets and could comment on them?
