Best helmet

Great helmet. The field of vision is superb, multi vents which have a great air flow coming in. There's hardly any wind buffering on motorways or fast roads and you feel safe with it. Top top lid but what do you expect from arai.

Very nice helmet

Had a Biltwell Gringo and bought the Arai for me to use, while the Gringo became the passenger's. Feel much, much safer. Comfort wise, not that much of a difference. The only difference is in regards to cooling - quantum leap difference. The padding is better, but not that much better. The weight is higher. The sound insulation is quite bad for a helmet this expensive. Pinlock does it's job during the day, but I see loads of reflections at night time, which sucks.

Great fit

This is my second Tour X4, after Tour X3. Great visibility and perfect fit for me, all day comfort, literally, worn for overnight National Rally - 18hrs+, comfy all day and also day in day out when touring. Didn't even consider anything else when previous one needed replacing due to age and miles. Also quick delivery and good communications from Sportsbikeshop

Great value & excellent quality

Bought as a second helmet and the fit of Arai is perfect for my head shape. Same size selected as a previous Arai purchase a long time ago. Excellent features and speedy service. Recent 150 mile on road / off road trip confirmed the quality

Great helmet for winter

Bought this as a second helmet for winter. It is so comfortable with a wind stopper neck warmer underneath. I ride a sports bike and removed the peak for road riding. Top quality helmet as you would expect from Arai. Great service from SPORTSBIKESHOP as it arrived within 24 hours and had a free Pinlock insert included.
