Customer Reviews for Arai Tour X4 - Diamond Black

Arai Tour X4 - Diamond Black
February 16, 2020

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.

Great buy

Fit and finish are second to none. The expression fits like a glove should be fits like a Arai Tour X4! OK bit of a mouthful but a 200 mile non-stop ride without niggling discomfort like you would get with a lesser lid makes the price tag worth it. Visor is a god send on the low in the sky sunny days and plenty of adjustable ventilation, the black sparkle paint is just darn smart!

Great value

Having returned to motorcycling after 3 years I was happy to find Arai helmets were in fit and finish as good as ever. 500 quid for a coloured one made this black one top value. I would never call it plain black as the paint has a deep lustre and sparkle to it.

Best helmet ever

I bought this for a BMW off road skills course I was doing and also for a hot weather helmet for a later holiday. The helmet is amazing. I have a Schuberth C3 Pro and this is better than that. It feels quieter somehow. The ventilation on this is second to none, especially the unique visor vents. They really help keep you cool. The visor is ultra quiet as well, no buffeting or vibration. This is a quality lid and the one I go to every time.

X4-for Xtreme Xcellence.

Over the past 40 odd years I have owned lots of different makes and colours of helmets. This is by far the best looking Arai I have owned. It fits really well and looks fantastic. In diamond black with an amazing shine with glitter effect. Even though I have rated it as high as I have, there is 1 small fault. The holes inside from the vents concentrate the air to that point on your scalp and becomes very sore. The way round this was to stick a strip of duck tape over the holes on the inside of the helmet. Very easy to do. Problem solved. Another great feature is the peak removal. Arai supply the side plates to keep the visor in place. Looks great with or without. Hardly any buffering with the peak attached. A superb helmet. The best I have ever owned. Well worth the price.
